Table 7. Validated
When the command 'AT+AUDIOFILE=”recordparam”,' is used, 0
is stored as duration instead of answering +CME ERROR: 3
returns OK instead of +CME ERROR: 4.
+AUDIOFILE test command print bad gain lower limit (-178
instead of -78)
adl_audioTonePlayExt() called with duration=0 (infinite
play) doesn’t work
Command processing from ADL halts if an AT command is sent
from external application at the moment when a low priority ADL Task was also
sending a command using ADL APIs.
Cannot use adl_atCmdSendExt() API with "ATA"
string if used with InBand Modem (or any plugin that uses ADL call services)
If some badly formed AT commands are sent by application,
it could end with a heap memory corruption
adl_tcuStop() function returns incorrect remaining time
Ring indicator may not working for AT+CREG=1 when
application is running.
When AT+CREG=1 command is issued and there is a cell
switching, unsolicited +CREG indication is received when application is in
execution and Airprime is in roaming state.
ADL command processing halts if SMS is sent right at the
time when an active voice call is disconnected by the peer
Airprime reset can occur if AT+ERAGCALLCANCEL command is
issued to cancel a call when a previous command to create a call using
AT+ERAGCALL has not yet created the call (by sending ATD command) when there
is no network available.
With certain USIMs, adl_simSubscribe () does not allows to
Reset Cause given in adl_InitGetType() is not correct when
Watchdog Reset happens during execution of Customer Task (0 instead of 1)

This section presents additional information or restrictions
that must be taken into account regarding Open AT OS 6.54.3.A1. Issues are
sorted by alphabetical order of Impacted Domain
Open AT restrictions linked to Firmware part are listed in “7.54.2.A1 Firmware
Customer Release Note”, document [R-3].
Table 8. Restrictions
and Additional Information
Error is not returned in case an attempt is made
to play or listen to an audio stream which is not supported by AirPrime.
Random value of "Context" is received
when API adl_atCmdSendText() is used after API adl_atCmdSendExt().
When FCM service is running with call services,
commands ATA, ATD, ATH cannot be filtered using the API adl_atCmdSubscribe().
On issuing a pre subscribed command from an
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.
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 application.
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.
On I2C bus, NACK is not detected as an error:
adl_busread() or adl_buswrite() return OK in this case.
With adl_adSubscribe() API, it is possible to
allocate only one cell with an undefined size, any further cell allocations
with undefined size cause the AirPrime to restart.
Module may reset if FCM service is concurrently accessed
to send data block by two tasks.
"+CGEREP" command can return "OK"
instead of "+CME ERROR: 11" when SIMPIN is locked and Application
Sometimes handler associated with
adl_errSubscribe() function is not invoked on reception of error from OS.
