1. New Features.

This section lists the features added from the previous Open AT® OS 6.32.

Open SIM Access for Q26 Extreme: As well as other 2G products, the Q26 Extreme is now supporting Open SIM Access feature.

EABI compilation: Open AT® OS and plug-ins are compiled in EABI. This library format allows any Developer Studio user to compile either with latest GCC or RVDS compiler and benefit from our RVDS performances for OS and plug-ins (code size, code speed).

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

CUS41819

When FCM service is running with call and/or SIM services, commands ATA, ATD, ATH, AT+CGANS, AT+CGACT, AT+CGDATA, ATO and AT+CPIN cannot be filtered using the API adl_atCmdSubscribe().

AT

OTHER

ANO41818

Subscription to commands beginning with "ATA", "ATD" or "ATH" using the API adl_atCmdSubscribe () fails in case Call service is subscribed prior to subscribing to the commands from the embedded Application.

AT

OTHER

ANO55998

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

CUS56898

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

ANO52140

Whenever the user tries to register a new device using API adl_odRegister() and then tries to open the newly registered device, the embedded module resets.

DEVICE

OTHER

CUS57032

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

ANO57629

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

CUS56598

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

CUS55995

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

CUS53324

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

ANO49342

When GPRS service is used in other task than main task, then it doesn't work.

OTHER

OTHER

CUS56908

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.

OK response is received when trying to write in flash memory even when there is not enough flash memory left to write. In case when not enough flash memory is left to write, ADL_FLH_RET_ERR_MEM_FULL response should be received instead of OK response, while trying to write in flash memory.

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.

CUS53427

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

ANO53391

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

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

ANO52364

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.

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.

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.

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.

CUS41867

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

CUS42575

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.
