Open AT OS 6.35 Release note

May 04, 2012 - Author: Sierra Wireless - Version 6.35 - 3611 Views

1. New Features

This section lists the features added from the previous Open AT® OS 6.34.

OS Clock: Offers system clock interface in ADL.

Open USB Interface: Ability to create your own USB composite thanks to existing Sierra Wireless USB interface (ACM interface) and other customized USB interfaces.

One Shot External Interrupt: The external interrupt is triggered in ADL only at the first occurrence, preventing it to generate multiple interrupt request in case of not acknowledging it immediately.

3. Known Restrictions

ID Description (What / When) Impacted Domain Impacted Sub Domain
55785 When DTR signal control is enabled by AT&D2, OK response is not received for call disconnection when the call is dropped using DTR signal. This incorrect behavior is seen when any embedded application is running in the background. AT OTHER
55998 When an embedded application release credit one by one by using the adl_fcmReleaseCredits() API, credit are not release and at a moment the transfer could be stop like the sender never received the resume indication sent by the FCM when credits are released. DEVICE FCM
56898 While using Open UART Interface, Parity is always returned as UART_PARITY_NONE when user tries to get the current line coding settings even if parity is set to UART_PARITY_ODD or UART_PARITY_EVEN. When parity is set other than UART_PAR_NONE_CAP then it should return the correct value whenever user is extracting the line coding settings. DEVICE OTHER
61027
A reset occurs when an embedded application makes use of realloc() function to reallocate the memory block
OTHER OTHER
60323
In all mono tasks ADL sample, the "adl_main" API is used as the sample entry point. This API is indicated as deprecated in the ADL User Guide. In all ADL samples, the task definition table should be used (like in the multitask ADL samples).
OTHER OTHER
57629 When API adl_osaSendResponse() returns ADL_RET_ERR_PARAM, many times on successive calls to the API adl_osaSendResponse() ADL_RET_ERR_BAD_STATE is returned even when all the parameters are correct. ATR or APDU responses could not be post back to the Firmware successfully after this. OK response should be received when API adl_osaSendResponse() is called with correct parameters. OTHER OTHER
57032 If a command with type ADL_CMD_TYPE_PARA is subscribed by using the adl_atCmdSubscribe() API, the handler provided is also called while issuing the test command i.e. "AT+<xxxx>=?". Command handler should be called after confirming that '?' is not given after '='. OTHER OTHER
56598 On issuing a pre subscribed command from an Embedded application, through the 'adl_atCmdSendExt()' API, an OK and ERROR is received alternatively, i.e. the command is sent to the command handler and the firmware alternatively. Ideally, the command should always be sent to the command handler and OK should be received. OTHER OTHER
55995 When we issue commands "AT+READ" and "AT+WRITE" using embedded sample application “external storage I2C”, OK response is received even though no external I2C device is connected. OTHER OTHER
53324 When Using %I64 format specifier for displaying u64/s64 variable through API adl_atSendresponse() in TARGET mode it always prints only "%I64d" instead of the value of the variable. Workaround: use %lld instead of %I64 OTHER OTHER
56908 When user sends the AT+CPIN command through the embedded application using the adl_atCmdSend() of command service API without providing the Notification identifier, the sim state in the ADL is not updated and it remains in the Wait state. The SIM related services like Call, GPRS become unavailable through the Open AT ®. Whereas in the ideal scenario, the sim state should be updated appropriately. SIM OTHER

4. Interface Modifications

This section lists the interfaces that have been modified from Open AT® OS 6.34
API Comment
Open UART (sUartSettings_t structure) Before using "UART3" with the Open UART interface, the USB function CDC ACM has to be opened first using the Open USB feature. Otherwise the UART3 is not available and cannot be used with Open UART.
malloc, calloc, free Some standard C library functions dealing with memory allocation (malloc, calloc, free) are now supported and can be used by Open AT applications without leading to a software crash.

53097 The Remote_terminal sample application provides incorrect usage of API adl_fcmSendDataExt(). DEVICE FCM 6.31
56110 When the user switches from AT mode to DATA mode using WIPSoft, sometimes CONNECT indication is received in between the data. If any application specifically checks for CONNECT after switching from OFFLINE to ONLINE, this will result in a failure. For the correction, a new ADL interface has been opened and called by WIPSoft 5.21 DEVICE FCM 6.31

The ME shall then deactivate the SIM/ME interface within 5 seconds and reject the SIM. However, ME sends a Select command instead of Status command and doesn’t deactivate the SIM. OTHER OTHER 6.31
51229 VCC voltage in 3V_5V mode is not managed correctly. OTHER OTHER 6.31
51233 SIM keeps switching on after OSA unsubscription as no power off request is sent to chipset to switch off SIM. OTHER OTHER 6.31
51441 As describe in ADL user guide "No TCU service API should be called from Low Level IRQ handler". It should be better that APIs return ADL_RET_ERROR_SERVICE_LOCKED error code. OTHER OTHER 6.31

50716 With the activation of OSA on sending APDUs, the Wireless CPU® resets with a backtrace. This is due to the SIM frame buffers not being reallocated. OTHER OTHER 6.31
52437 The Wireless CPU® reset is observed when UART Access sample application tries to Open UART2 when UART2 is not free or tries to Open UART2 in DCE mode. The application should not reset the Wireless CPU®, but instead should return ADL_RET_ERR_BAD_HDL error. OTHER OTHER 6.31
53190 The extintSubscribe () API returns -13 (i.e. ADL_RET_ERR_NOT_SUPPORTED) when the sensitivity level is set “ADL_EXTINT_SENSITIVITY_HIGH_LEVEL” or “ADL_EXTINT_SENSITIVITY_LOW_LEVEL”. Support for sensitivity level “ADL_EXTINT_SENSITIVITY_HIGH_LEVEL” or “ADL_EXTINT_SENSITIVITY_LOW_LEVEL” is not provided yet. Documentation tracker is to be raised to mention the same in the ADL User Guide. OTHER OTHER 6.31
53196 In Telemetry sample, before writing into flash, the flash handle is not subscribed (there is no usage of "adl_flhSubscribe()"), this causes problem while saving the parameter via custom command +IOSET and +TEL. OTHER OTHER 6.31
53423 The GPRS subscription fails on first usage of the ADL API adl_gprsSetupExt(). On using the API again (i.e. 2nd time) the GPRS subscription passes. OTHER OTHER 6.31
54718 If the result of adl_memGet() is not checked against NULL value, the Wireless CPU® resets when we try to write to the NULL pointer. The return value of function adl_memGet() needs to be checked against NULL in order to avoid the reset on Wireless CPU® before write operation. OTHER OTHER 6.31
55539 When USB UART is used, successful asynchronous write will return CH_STATUS_NORMAL instead of CH_STATUS_PENDING. OTHER OTHER 6.31
50010 In RTE mode, When application calls adl_regGetHWDataChunk() functions with ByteCount parameter set to null, then a WCPU reset occurs 6.30
51234 Wrong parameters during ATR command sending procedure in OSA sample.
Workaround:Data must be a pointer instead of a variable
6.30
51510 In RTE mode , adl_bus_read() is not functional.
adl_busRead() call resets Target (backtrace).
6.30
51730 51731 Wireless CPU resets when adl_bus_read() and adl_bus_write() API's are used in RTE mode. 6.30
52221 With the activation of OSA on entering the SIM PIN code, the WCPU resets with a backtrace. 6.30
52642 With the activation of OSA on removing the remote SIM before +WIND: 4 indication, the WCPU resets. 6.30
52692 When using adl_eventWait and setting a timeout of n seconds the timeout will effectively occurs after n*4 seconds 6.30
53054 When the application opens a device with Open Device services, for example an UART, and close it, there is a memory leak 6.30
53427 When the "UART_access" sample application tries to Open UART2, when it's not free or to open it in DCE mode then the WCPU resets. Application should exit gracefully and proper error handling should be implemented in the application. 6.30
53391 Using IDS services, an Open AT® application can subscribe to monitoring mechanism in order to make report to the IDS server with application data.
In the subscription, a configuration is required. When the application init is made several times, the configuration is overwritten each time in flash. Any update from the IDS server on a parameter configuration is then lost and a desynchronisation appears between the device and the IDS server. When a configuration is already present in flash for the Open AT® application parameter, the FW should not overwrite the configuration in flash
Embedded RDMS RDMS 6.30
51709 When sample application tries to Open UART2 when it's not free or to open it in DCE mode then a WCPU reset occurs. Application should return an error. 6.21
52364 Second FAX call cannot be handled due to there is no terminal response send from ATI to OAT. Due to this AT commands initiate by ADL are saved in the stack waiting for the answer of first ATA command. ATI should send a terminal response to OAT with a new flag, so that OAT can unblock the queue and the terminal response will not be displayed in the terminal. 6.21
52550 RI doesn't function for setting +WRIM=1,2,1000 (i.e. RING [bit:1]) and Open AT application is enabledANO525 6.21
52826 If application have set ASYNCHRONOUS mode for I2C or SPI bus, then there is a memory leak when application unsubscribe to the I2C or SPI bus. 6.21
53516 When sample application tries to Open UART2 when it's not free or to open it in DCE mode then a WCPU reset occurs. Application should return an error. 6.21
48936 Backtrace while FCM subscription, Outgoing data call and 30 tasks running. 6.21
53478 53454 The stack size in "adl_InitTasks_t" cannot be declared more than 64K 6.21
41865 Application is not able to subscribe to AT commands that are subscribed by ADL, ref : "Inner AT commands Configuration" paragraph in ADL Documentation. 6.20
50881 Flash operations take too long time 6.20
49697 Signal Generator example does not work.
adl_tcuStart() or adl_tcuStop() API doesn't works in low IRQ handler, as described in ADL user guide
6.20
50907 Sample Sound Demo adaptation.
There is a change in Audio service behaviour about the note definitions. Since Open AT® Software Suite v2.10 there is a change on frequency range according to note scale. For a same note scale, now frequency range is lower. So melody which has been defined in Open AT® application before Open AT® Software Suite v2.10 could be now too low in frequency, so it could not be heard.
6.20
51169 Unsubscribe the OSA is impossible when an APDU request is unanswered. 6.20
51544 RI signal is not pulsed for unsolicited response chosen with +WRIM AT command if an Open AT® application is running. 6.20
50000 When some ADL functions are called in Open UART callback functions, then a WCPU reset occurs. ADL_RET_ERR_SERVICE_LOCKED error code should be returned 6.20
49761 IDS Sample not functional with ADS or RVDS compilation. 6.11
50448 Timeout of Event is not functional. 6.11
47297 "ADL_SIM_EVENT_PIN_NO_ATTEMPT" is only received for pin code sent with adl_simSubscribe() or adl_simEnterPIN() but not with pin code sent from external. 6.10
41747 After OSA service subscription with adl_osaSubscribe() function, if the application tries to unsubscribe to the OSA service without posting back an ATR request to the Sierra Wireless firmware (after an ADL_OSA_EVENT_ATR_REQUEST or ADL_OSA_EVENT_ADPU_REQUEST event), then the unsubscription will fail, so the OSA service is never closed and it's not possible to subscribe again to it. 6.02
41829 Problem occurs when trying to activate a context with adl_gprsAct (), ADL_GPRS_EVENT_ACTIVATE_OK is not associated with the good cid number 6.02
41834 When up to 2000 A&D cells are created by an application (whatever are the cells' sizes), the adl_adGetCellList function will lead to a Wireless CPU® watchdog reset. 6.02
41836 ADL is not currently supporting the ATQ1 mode; this mode is mandatory to keep an ascendant compatibility with old external applications using only some basic AT commands. 6.02
41846 The adl_fcmUnsubscribe () API returns an incorrect value of FCM flow when called immediately after adl_fcmSubscribe() API. 6.02
41860 Even if ADL manages the ATQ command mode, there is no way for the application to internally control the current value of the quiet mode. 6.02
41863 When "ADL_TMR_TYPE_100MS” timer is subscribed, if "TimerValue"parameter is superior to "0x5E9182"value, the timer will not be set with the required value. Accordingly there is a limitation when "ADL_TMR_TYPE_100MS” timer is used. 6.02
41866 When an application subscribe to the SIM service with a correct PIN code (with adl_simSubscribe() function ), if it unsubscribes to this service and tries to subscribe it again a second time with an other SIM and PIN code , then "ADL_SIM_EVENT_PIN_ERROR” event will be raised. User cannot change the SIM card with another one which has a different PIN code. 6.02
41867 ADL SIM service is not informed that a PIN code is entered when the AT+CPIN command is sent with the adl_atCmdCreate() function. And then the other services depending on the SIM state do not work properly (SMS, CALL & GPRS services) 6.02
42575 This error happens when an unsubscribe request occurs exactly between 2 timer cycles. During this period, an unsubscribe request of the cyclic timer can be done but returns an error message. It’s because the timer is restarting. Increasing the TimerValue reduces strongly the probability of getting this error. To get an accurate time measure, the SCTU service must be used. 6.02
43589 If IRQ Low and High handlers are subscribed and DTMF detection is started with adl_audioStreamListen API, when an IRQ occurs the Wireless CPU® will reset 6.02
43775 Some special strings used in ADL can't be sent by SMS (OK, CONNECT, ERROR 6.02
44468 Open AT® application is now correctly informed of port opening. 6.02
44495 When adl_atCmdCreate API is used with ADL_PORT_NONE parameter, then AT command is sent to the Wireless CPU® on the ADL_PORT_OPEN_AT_VIRTUAL_BASE port 6.02
44783 The customer application will be informed of a call release event by toggling DTR. 6.02
45017 Starting from a too big DOTA volume size (e.g. AT+WOPEN=6,2624) adl_adRecompact starts correctly but does not generate any events. 6.02
45024 ADL badly handles the AT+WOPEN=6 mode when safe mode service is subscribed (size systematically set to 123) 6.02
45490 When a task has been interrupted by an ISR, adl_ctxGetState returns ADL_CTX_STATE_SUSPENDED instead of ADL_CTX_STATE_PREEMPTED. 6.02
46854 "+CMS ERROR: 539" will now be handled so that the reading of the current SMS is discarded (since invalid) and the SMS service is ready to process further incoming SMSs. 6.02
47156 when an application uses adl_smsSend() API to send a SMS, if the phone number parameter is a NULL string so the SMS is not sent but the SMS service enters in an invalid state. The application is not be able to send again another SMS. 6.02
41853
41854
The Signal Replica sample HTML documentation for AT+SIGNAL command is not coherent with the real command behavior. 6.02
41861 During an interrupt routine, it is impossible to use adl_extintConfig. 6.02
41868 When an application unsubscribe to a timer which have been already deleted, ADL can delete another timer handler subscribed. So this last timer handler is not notified when the timer expired. 6.02
45667 A reset occurs when a try is made to unsubscribe the bus during a read or write. 6.02
41859 The sample Sms_Automaton does not check if the starting tag and the ending tag are the same. 6.02
