1. New Features

This section lists the features added from the previous Open AT® OS 6.35.

Embedded Debugging: Enables developers to speed up embedded software fine-tuning by managing application execution through suspend/resume, step-by-step, standard and conditional breakpoints, and data watch capabilities in conjunction with Developer Studio.

Note 1: library/application has to be compiled in DEBUG mode to be able to use it. Library/application compiled in RELEASE mode can’t be debugged.

Note 2: JTAG debugging is still supported for backward compatibility on WMP series.

UART Pin Interrupt: In order to offer a new wake up mechanism from the Sleep mode, ADL now allows mapping of external interrupt on some UART signals (RXD pins of UART1 and UART2, and DTR of UART1). This feature is available in beta stage.

Power Down Management: Improved power down management for Open AT application by fine tuning which software area are not allowed to enter in Sleep mode. This feature is available in beta stage.

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.

60390

The embedded module gets reset in case an embedded application using SMS service is running on it and an SMS is received with the storage memory selected for reading and receiving the SMS being different. After the reset is fixed the CMTI indication received on terminal always shows that message is stored in SIM memory even if some other memory e.g. “ME” is selected for storage.

The embedded module gets reset in case an embedded application using SMS service is running on it and an SMS is received with the storage memory selected for reading and receiving the SMS being different.

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

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

API

Comment

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.

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

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.

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.

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.
