1. New Features

This section lists the features added in this release.

  • File System: ADL now provides interface to handle a fail-safe file system operations.
  • I2C bus Reset:I2C bus can be reset using API adl_busIOCtl(). New command Option ADL_BUS_CMD_RESET_BLOC can be used for this purpose.
  • I2C bus Watchdog: The synchronous watchdog associated with I2C bus can now be configured using API adl_busIOCtl(). New command Option ADL_BUS_CMD_SET_SYNC_WATCHDOG, ADL_BUS_CMD_GET_SYNC_WATCHDOG can be used for this purpose.
  • Sleep Mode Control:DTR signal can be used to wake-up the embedded module when Open UART service is used.
  • PLMN Scan information:The ADL API of the existing Layer 3 Service has been extended to deliver Cell Allocation information of serving cell, giving frequency number of cell allocation and frequency list.

63727 TCU ADL service is not operational RTX OTHER

55998

When an embedded application releases credit one by one by using the adl_fcmReleaseCredits() API, credits are not released and at a moment the transfer could be stop like the sender never received the resume indication sent by the FCM when credits were released.

DEVICE

FCM

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

53530

If command AT&F is sent using adl_atCmdCreate(), CME/CMS Errors are not reported for further commands.

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

41818

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

OTHER

OTHER

41819 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() OTHER OTHER

4. Interface Modifications

This section lists the interfaces modifications introduced in Open AT OS 6.51.

API

Comment

adl_busIoCtlCmd_e

New values,ADL_BUS_CMD_SET_SYNC_WATCHDOG, ADL_BUS_CMD_GET_SYNC_WATCHDOG, ADL_BUS_CMD_RESET_BLOC are introduced to allow configuration of synchronous watchdog timer & for the reset of the I2C BUS.

adl_ctxState_e

Unused fields have been removed and this enumeration is simplified to hold following values only:
(ADL_CTX_STATE_ACTIVE, ADL_CTX_STATE_WAIT, ADL_CTX_STATE_READY, and ADL_CTX_STATE_SUSPENDED)

wm_l3info_Cell_SyncCellInfo_t

When the embedded application subscribes to the ADL_L3INFO_CELL channel and when the WM_L3_INFO_SYNC_CELL_INFO event occurs, the data which are returned by the firmware were updated. A new field was added in the wm_l3info_Cell_SyncCellInfo_t structure in order to return the Arfcn list of the serving cell.

adl_atCmdCreate
adl_atCmdSend
adl_atCmdSendExt

While using anyone of these API's and parameter “rsphdl” is provided as NULL, then the list of subscribed responses is ignored.

adl_tmrUnSubscribe

Return code “ADL_RET_ERR_PARAM” is returned if the TimerType is not the same as the one used while subscribing the timer.

adl_simEnterPIN

Error code “ADL_RET_ERR_BAD_STATE” will be returned from this API when a wrong PIN is provided and there is only one attempt left for SIM PIN.

adl_rtcTime_t

Valid range for structure member “WeekDay” is updated to “0-6” instead of previous “1-7”.

adl_strID_e

Enumeration is updated to make string “+CPIN2” available for use with AT string services.

When the Network forces ME to change GPRS mobile class to CC, ADL_GPRS_EVENT_NW_CLASS_CC event is not received.

GPRS

OTHER

Incorrect CID value (5) is returned by the GPRS event handler, on trying to activate PDP context on correct CID value (1-4), when an embedded application which subscribe to GPRS service is downloaded onto the module.

When an embedded application is running and a concatenated command including “+CPIN2?” is issued, response is not received for commands following “+CPIN2?” in concatenated command string. In addition to this, the command class remains locked. As a result of this +CME ERROR: 515 is received for further AT commands.
