adl_pwrdwnSubscribe

This function allows the application to get control over the Power Down service.

adl_pwrdwnUnsubscribe

This function allows the application to unsubscribe from the Power Down service.

adl_pwrdwnAllowed

This function allows the application to allow the 32Khz mode Open AT service.

adl_pwrdwnForbidden

This function allows the application to forbid the 32Khz mode Open AT service.

adl_atCmdCreate

When using this function to change the UART settings by giving AT+IPR or AT+ICF command, the response will not be received on terminal even if the parameter rspflag is set as TRUE.

adl_fcmSubscribe

When this function is used for USB port then PORT services must be subscribed. When the USB cable is unplugged, the FCM service automatically gets unsubscribed and correspondingly the FCM control event handler is notified by the ADL_FCM_EVENT_FLOW_CLOSED event.

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.

60293

When AT+IPR and AT+ICF commands are issued through an Embedded Application using the adl_atCmdCreate API and if the rspflag parameter is set as FALSE, the settings are not reflected on physical UART. UART settings to be set are reflected only after any AT command is issued through an external application.

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.

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.

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.

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.

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.

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

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 "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.

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.
