1. New Features.

This section lists the features added from the previous Open AT® Firmware 7.4.

Auto quad-band: In auto quad-band mode, the Wireless CPU® automatically chooses between the 900/1800 MHz bi-band or the 850/1900 MHz bi-band according to the radio environment. This feature is now available in release stage. For more information, refer to AT+WMBS in AT commands Interface Guide.

1K-Xmodem download through USB and UART2: The new bootloader is supporting the 1K-Xmodem protocol over USB and all UARTs to download a new binary in DWL format (either bootloader, Open AT® Firmware or Open AT® applications). It also means that the M2M Studio is able to download over USB and all UARTs any binary in DWL format. This feature is still available in beta stage. For more information, refer to AT+WDWL in AT commands Interface Guide.

Wireless CPU ® default serial port is UART1 and USB: UART1 and USB serial ports are activated by default for all Wireless CPU® produced with Open AT® Firmware 7.4. This feature is now available in release stage.

3. Known restrictions

Id Description (What / When) Impacted Domain Impacted Sub Domain
ANO41916 When the Open AT application use the AT+CUSD command to send USSD strings to the network, by using the GSM 7 bit default alphabet table (defined in GSM 23.38 specs), and when the USSD string contains some extended characters like [,], {,}, ,¦, ~ and ^, that are not defined into the GSM 7 bit alphabet table, the Wireless CPU replaces each extended characters by 0x20. AT OTHER
ANO41921 When +WDIAGI indications are activated (AT+WDIAG command), some unsolicited responses are returned by the Wireless CPU during an MO data call between CONNECT and NO CARRIER responses. These indications should not be returned AT OTHER
ANO41927 A command is sent and an unsolicited response (+CREG: 2) is returned before the OK response. Normally the unsolicited response has to be returned after. AT OTHER
ANO41929 Autobauding is not able to resynchronize with the Wireless CPU after a NO CARRIER response is received after releasing an active GSM data call. This is only met if customer changes speeds between establishing and releasing the data call. AT OTHER
ANO41934 Interrogating the Call Forwarding state on a specific class (voice (AT+CCWA=1,2,1 )or data (AT+CCWA=1,2,2) or fax (AT+CCWA=1,2,4)) returns +CME ERRRO: 30. The Call Forwarding state of the required class should be returned by the Wireless CPU. Interrogating the Call Forwarding state of all classes (AT+CCWA=1,2,7) is working. AT OTHER
ANO41938 When an outgoing call is in progress (ATD command) and not yet established, +WAC command resets the ATI automaton. In this case, all AT commands sent after +WAC command and before OK response to Dial command returns the corresponding response instead of +CME ERROR: 515. The Wireless CPU should return +CME ERROR: 515. AT OTHER
ANO41947 Impossible to modify PIN1 value before receiving +WIND: 4 indication. It should be possible to modify the PIN 1 code between the moment when this code is entered (and validated) and +WIND: 4 indication AT OTHER
ANO41948 Incoming Data Call gets connected even when the IPR and the DTE-DCE data rate are different. AT OTHER
ANO41950 If the SIM contains sufficient EXT files, AT+CPBW=? can return a max phone length equal to 80 digits. But if an entry with a phone number containing between 61 and 80 digits is tried to be written, +CME ERROR: 20 is returned by the Wireless CPU®. The entry should be written (if SIM contains sufficient EXT files). AT OTHER
ANO41952 In SLOW CONNECT mode (AT+WGPRS=5,1) for PALM OS, when a GPRS session is launched, CONNECT response is sent as response instead of data response AT OTHER
ANO41954 When setting the speed of serial link to a speed lower than 9600, this speed is displayed into the CONNECT response instead of the data call connection rate. AT OTHER
ANO41957 When AT+CGDATA=<cid> is entered, GPRS session is not activated and then "NO CARRIER" returned. AT OTHER
ANO41968 When MCC Lock feature is activated and an invalid SIM is inserted, the "SIM NOT ALLOWED FOR THIS MODULE" message is not returned by the Wireless CPU® through all opened ports (physical or virtual). If only UART 1 is opened, the message is always returned through UART 1 but if several ports are opened, the message is not sent to all ports. This message should be returned by the Wireless CPU® through all opened ports. AT OTHER
ANO41969 When the MCC lock feature is activated, the SIM removal is not detected in the following procedure: 1) Insert an invalid SIM card (SIM NOT ALLOWED FOR THIS MODULE is returned by the Wireless CPU. 2) Remove the invalid SIM and insert a valid SIM 3) Enter the CHV1 code. 4) Remove the SIM. The SIM removal is not detected, +WIND: 0 is not returned by the Wireless CPU®. The SIM removal should be immediately detected and +WIND: 0 indication should be returned by the Wireless CPU®. AT OTHER
ANO44395 When the AT command parser is locked (see AT+WCMF command), if an Open AT application is downloaded and executed on the Wireless CPU, it is possible to issue AT commands. Ideally, since the AT command parser is locked, AT commands should not be allowed, even when Open AT application is under execution. AT OTHER
ANO45835 If user configures CGAUTO different from default value (3), it is impossible to answer to an incoming GSM voice call (automatic or manual) AT OTHER
ANO46467 When Wireless CPU® is in roaming and when PLMN is changed, +CREG: 5 indications are not received. AT OTHER
ANO47805 If an OAT application is started and when the user establishes a GPRS call, the +ILRR indication is returned by Wireless CPU after the call (i.e. after the NO CARRIER indication) and not before the switch in data mode (before the CONNECT indication). AT OTHER
ANO52024 As a response to "AT+WGPRS=?" command, the PDP context identifier should be in the range of 1-4 and not in the range of 0-4. AT OTHER
ANO54733 When auto answer is activated on a closed port, a reset happen when an incoming call is received. This reset should not happen on target because S0 command is working on the port on which is sent and auto answer is reset when the port is closed. Only can happen when a bad E2P corruption or when a bad E2P file is downloaded. AT OTHER
ANO54845 [Q26Extreme] After network registration, changing the SIM pin code 3 times with incorrect pin code, the unsolicited response +CREG: 0 is not shown (Network registration is enabled with AT+CREG=1 command). AT OTHER
ANO54848 [Q26Extreme]When the SIM pin is blocked and unlocked with the SIM PUK, no unsolicited responses +CREG: 2 and +CREG: 1 are received even when the network registration is enabled (AT+CREG=1,1). AT OTHER
CUS41983 In 14.4 Kbits V.110 connection (+CBST: 75,0,1), the CONNECT response is not sent as DATA but as AT intermediate response. Because of which, in 7E1 framing, the CONNECT string is not in the right format (framing issue). The CONNECT response should be correctly returned by the Wireless CPU® and in the right framing. AT OTHER
CUS45350 When the Wireless CPU is configured with AT+WBHV=0 (to send the terminal response of an outgoing call when the audio path is established), the command AT+CLCC shows active call even when a wrong number is called. AT OTHER
CUS49812 If a port, where the auto answer has been configured (ATS0), is closed, the auto answer value is reset to zero. AT OTHER
CUS54702 When a band change is made with a hot reset (see +WMBS command description), the OK response is returned by the Wireless CPU while the protocol stack is treating the band change. So when this OK response is returned by the Wireless CPU, the protocol stack is not ready to treat any request.
In this case, sending +CSQ command to the Wireless CPU just after the OK response of the band change with a hot reset does not return any response and no more AT commands can be sent to the Wireless CPU (+CME ERROR: 515 response is always return). The Wireless CPU should return an error to the +CSQ command while the band change is not terminated.		 AT OTHER
ANO40680 On deleting an entry while FDN to ADN swap is in progress, the module goes in hang state. No further AT commands can be processed in this state. AT PHONEBOOK
ANO41928 When ME phonebook is full and SIM phonebook has 127 entries, module resets immediately after entering the PIN code. AT PHONEBOOK
ANO41953 When an entry from the LND is displayed, sometimes the name field of the entry is missing AT PHONEBOOK
ANO41967 When the format used to search a phone number into a phonebook is not the same as the stored number, the AT+CPBP command does not list the matching entry. AT PHONEBOOK
ANO42185 When the flash phonebook is full with all the entries with the same name, the Wireless CPU resets when we try to delete some entries. AT PHONEBOOK
ANO41992 When the Wireless CPU is configured to display and record the SMS-STATUS-REPORT, several +CDSI indication are displayed and saved into memory for the same SMS (instead of only one per SMS). AT SMS
ANO48617 If a user send or write the SMS with DCS as default GSM and store it in ME memory, then the SMS data when read is not displayed correctly. The bytes in the user data field got changed. This problem is not reproducible when SM memory is used. AT SMS
CUS41955 SMS present in ME is not displayed correctly in PDU format when PCCP437 character set is selected. AT SMS
CUS54582 When an incoming SMS is received by the Wireless CPU and if this SMS contains a header (User Data Header), this header is displayed in text mode (see +CMGF command) even if the corresponding characters are not ASCII one. Because the Wireless does not support any SMS header, it should not be returned in SMS read response (see +CMGR and +CMGL commands) and only the SMS text (User Data) should be returned in text mode (see +CMGF command) AT SMS
ANO51793 When a get input is received with @ (i.e. 0x00) in the text string, only the characters before the @ are displayed. It is because the intermediate response can only display a null-terminated string. AT STK
CUS55408 STK application failed to send a USSD request to the network when the DCS is equal to 0x40. The Wireless CPU® shall indicate the alphabet used in the operation and shall be set to "SMS default alphabet". The language indicator shall indicate "language unspecified". (i.e. 0x0F) AT STK
ANO55287 From R7.4a, the Wireless does not return anymore +CME ERROR: 545 error when +CMUX command is sent to the Wireless CPU while a MUX session is already launched on another physical port.
Also, several MUX sessions can be launched at the same time on different physical ports.		 DEVICE CMUX
CUS53392 During I2C read, when a nack appears the SCL line can stay low DEVICE IOB
ANO49559 Using AT+W32K=1,0 and AT+CMUX AT commands to authorize Slow idle mode on enabled CMUX com port and ignoring DSR state, the Wireless CPU does not enter low power mode. DEVICE MUX
ANO56345 Working with two simultaneous data flow on the both UART in CMUX mode is difficult, the data flow are often corrupted or interrupted. DEVICE MUX
CUS56232 When CMUX configuration is set and sleep mode is enabled (AT+W32k=1), sleep mode may not be effective. On DTR drop, PSC (sleep frame) is sent, but Wireless CPU® may not have entered in sleep mode. DEVICE MUX
ANO49719 Even if the Device Services are in prohibited state (see +WDSG command), if the firmware is downloaded in the Wireless CPU using the customer or production WPK, the Device Services flash volume is allocated (one 64kB sector for a 32Mb flash and four 64kB sectors for a greater capacity flash).
Then, AT+WOPEN=6 command sets and returns the size of DOTA+DS volume and not only the size of DOTA one.		 DEVICE OTHER
CUS53820 Whenever UART2 is opened by Open AT application using ADL API at AUTO BAUD RATE, baud rate of the UART will get fixed after the first communication with hyper terminal or any other application. The baud rate will not get changed after that which will lead to an erroneous communication with different baud rates. DEVICE OTHER
ANO55620 A MUX session cannot be opened with MuxConfTool on USB port. DEVICE USB
ANO55500 The WCPU resets if a large DLE/ETX sequence is transferred using TCP/UDP socket which is created on UART bearer using WipSoft. DEVICE V24
CUS41981 When an Open AT® application is running, indicating on which unsolicited response a RI PULSE should be made using +WRIM doesn't work and RI PULSE is not working. Currently, if bit 16 of 2nd parameter of +WRIM command is activated, RI PULSE will happen for all unsolicited response when an Open AT® application is running. The behavior should be the same than when no Open AT® application is running: selecting specific unsolicited responses on which RI PULSE is made should work when an Open AT® application is running. DEVICE V24
CUS54050 The Wireless CPU crashes when the handshakes of UART2 are active (AT+IFC=2,2) and nothing is connected to UART2 (free). DEVICE V24
CUS54170 RTS signal is followed even when RTS following is disabled with AT+IFC=0,2 command. Ideally RTS signal toggling should not have any effect after AT+IFC=0,2. No Data is displayed e.g. Response for AT, when the RTS signal is set to low with AT+IFC=0,2. AT Response should be displayed as with AT+IFC=0,2 RTS signal should not impact the behavior after setting RTS to Low. DEVICE V24
ANO55836 The reverse delta is not automatically installed after an IDS update, if the new update causes watchdog resets in loop. DWL OTHER
DEV50869 During an IDS update, if the recovery mechanism has deactivated the oat application, and if there is a hard reset, an XModem download is launched instead of the update agent. DWL OTHER

ANO52244 Using IDS services, uplink and downlink bandwidths of a device are not available. However, the bandwidth calculation is always wrong and the reported values by the device should not be taken into account by the IDS server until the correction. The bandwidth calculation should be correct in order to report the correct values to the IDS server. Embedded RDMS RDMS
ANO52346 When an update package tries to be downloaded by a device using IDS services and when the user agreement for download is activated, a "+WDSI: 2" indication is returned by the device. If the application decides to launch another IDS session with the server using AT+WDSS=1,1 instead of responding to the user agreement using +WDSR command, the download is made. In this case, the response to +WDSS command should be OK, a new "+WDSI: 2" indication should be returned indicating that the user agreement for download is requested and the package should not be downloaded. Embedded RDMS RDMS
ANO52510 Using IDS services, uplink and downlink bandwidths of a device should be available. However, the bandwidth calculation is always wrong and the reported values by the device should not be taken into account by the IDS server until the correction. The bandwidth calculation should be correct in order to report the correct values to the IDs server. Embedded RDMS RDMS
ANO52636 When a manual fallback is asked with the +WDSF command whereas no install succeeded before, the manual fallback should be failed and +WDSF should be answered an error Embedded RDMS RDMS
ANO54016 Using IDS service, the Wireless CPU can send an automatic report to the IDS server when a trigger is configured for coverage. When the triggered value is reached, the value sent to the IDS server can be out of range (range = [0-100]). The value should be always in range and correct. Workaround: On server side, when an automatic report is received for coverage in case of trigger, a GET command can be requested for coverage (the value is always correct in this case). Embedded RDMS RDMS
ANO56319 [Q26Extreme]Making a connection to the IDS server using +WDSS command returns an error, when the cell capabilities are in 3G R99. The Wireless CPU® should make the connection successfully in all 3G Cell capabilities. Embedded RDMS RDMS

When a CMUX session is started on the Wireless CPU without MUX protocol establishment, the session was formerly closed after 30 seconds, from R74a it is closed only after a 5 minutes timeout.


5. Corrections & Improvements

Id Description (What / When) Impacted Domain Impacted Sub Domain Fixed in
ANO51295 The Wireless CPU® returns CONNECT XXXX for AT+CGDATA=1,1 command and produces data flow even it is not located over network. AT OTHER 7.4a
ANO52081 Wireless CPU® can reset if user wants to enter in DATA mode or exit from DATA mode on a closed port. AT OTHER 7.4a
ANO52946 If there is only one PLMN entry in the sim card, the response of command AT+CPOL? results in the infinite loop which eventually deplete all the heap resources. AT OTHER 7.4a
ANO53087 The Wireless CPU® resets when AT+CUSD command is issued large number of times to send an USSD in UCS2 format. AT OTHER 7.4a
ANO53848 When repeatedly sending blocks of data for some time with AT+CPOF sent through an application at regular intervals the Wireless CPU hangs up and does not responds to AT commands. AT OTHER 7.4a
ANO53934 The command AT+WASR=1,1,"GpioId" gives +CME ERROR: 3 instead of expected CME ERROR: 501 when the GPIO is not allocated.
Also it returns +CME ERROR: 501 instead of expected +CME ERROR: 3 when the GPIO doesn't lies in the possible range.		 AT OTHER 7.4a
ANO54124 When the SIM is removed from the SIM rack while the Wireless CPU is listing the preferred PLMN (see +CPLS and +CPOL command), a reset happens. The Wireless CPU should not reset and a specific error should be returned to AT+CPOL? command (+CME ERROR: 556) AT OTHER 7.4a
ANO54586 When the Wireless CPU® is registered on a network and camped to a cell supporting GSM and GPRS services, if the autoquadband mechanism is launched (using +WMBS command) and if a power off is requested (+CPOF, +CFUN, etc...), the Wireless CPU® launches a new registration sequence instead of making a power off. The Wireless CPU® should not register again to the network until the next start up (hot or cold restart using +CFUN command for example). This doesn't happen with a cell supporting the GSM service only (not linked to the device class) AT OTHER 7.4a
ANO54934 On issue of AT+WOPEN=2 command, the first argument was erroneous in case of firmware version B74f. For the ideal scenario, the response should be the correct version of the OS that was released with the Firmware i.e. v06.31 for FW version B74f onwards till B74l. AT OTHER 7.4a
CUS53004 Audio (Melody) is stopped when a Call Waiting indication is received for the second incoming call over an ongoing call. No melody is heard after the BEEP sound of the Call Waiting indication as the audio resource SPEAKER is now allocated to Call Waiting indication and context for audio (Melody) is lost. AT OTHER 7.4a
CUS54251 In case the Wireless CPU® is in sleep mode the customer is not able to notice the mode as sleep mode because the CTS signal does not follow the DTR signal. CTS signal should not follow the DTR signal in case of normal mode but in case of sleep mode the CTS signal should follow DTR signal. AT OTHER 7.4a
CUS54368 The Wireless CPU® provides an AT command in order to read the IMEI (see +WIMEI command), using it a large number of times (more than 1000 times) makes the Wireless CPU® reset. Ideally, the Wireless CPU® should not reset in this case. AT OTHER 7.4a
CUS54579 No +WIND: 9 and +WIND: 2 indications are received in case AT+WAC command is issued after an attempt to make a voice call with the command ATDxxxxxxxxxx; +WIND:9 and +WIND: 2 indications should be displayed as the functionality of AT+WAC command is used to abort only SMS, SS and PLMN selection related commands. AT+WAC should not have any effect on ATDxxxxxxxxx; command. AT OTHER 7.4a
ANO48610 Although, the phonebook record has not been changed, the phone book status is wrongly displayed in "+WIND 10" indication. AT PHONEBOOK 7.4a
ANO51561 ATDxxxxpxxxxxxxxxxxxxxxxxxxx; calls the number with the DTMF Sequence and this sequence is stored in the LND phonebook wrongly reserving an EXT Record as DTMF sequence (after 'p') should not be stored in the LND phonebook. When the user again dials a similar sequence, the number is not stored in the LND as the EXT record has been reserved by the LND for the previous dialed number. AT PHONEBOOK 7.4a
CUS54033 When the size of the phonebook object is set with 0xFFFF in the Wireless CPU, a watchdog reset is observed few seconds after the SIM PIN code entry (if the SIM PIN code check is enabled) or few seconds after the SIM insertion (if the SIM PIN code check is disable). AT PHONEBOOK 7.4a
CUS53678 The PDU response of the SMS STATUS REPORT is incorrect as some extra bytes are received when status report is stored in FLASH. Also when the status report is stored in the Elementary file of SIM, the response is incorrect. AT SMS 7.4a
CUS55211 If a user sends or write the SMS with DCS as default GSM and store it in ME memory where the character set selected is PCCP437, then the SMS data when read is not displayed correctly when ME memory is selected.

CUS54758 Call index in the +WIND: 5,x and +WIND: 6,x is equal to 2 even if +WIND: 6,1 response has been received for the first call and the call has been disconnected. As the first call has been disconnected successfully the call index for the second call should be 1 in +WIND: 5,x and +WIND: 6,x wind responses. The issue is reproduced when ATD for the second call is made before receiving the CC_REL_IND. GSM CC 7.4a
ANO54248 When the Wireless CPU® is registered on a cell providing only GSM service (and no GPRS/EDGE service), the autoquadband mechanism (see +WMBS command) is not correct. The Wireless CPU® will change every time the frequencies (850/1900 <-> 900/1800) even if the GSM service is available on one frequency. The Wireless CPU® should launch the autoquadband mechanism and should stop it when it's registered on cell. GSM OTHER 7.4a
