Table 10. Restrictions and Additional Information

Issue ID	Description (What/When)	Impacted Domain	Impacted Sub-Domain
66697	Random value of "Context" is received when API adl_atCmdSendText() is used after API adl_atCmdSendExt().	AT	OTHER
41819	When FCM service is running with call services, commands ATA, ATD, ATH cannot be filtered using the API adl_atCmdSubscribe().	AT	OTHER
77817	When opened in WRITE mode, a file must not be accessed by any URL related API (as adl_fsMove(), adl_fsRename(), adl_fsDelete()), until it has been properly close with adl_fsClose(). Otherwise the File System can be corrupted	FLASH	OTHER
56598	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.	OTHER	OTHER
66337	Error is not returned in case an attempt is made to play or listen to an audio stream which is not supported by AirPrime.	OTHER	OTHER
75679	Error is returned and command handler is not invoked for any custom command when command is sent using the API adl_atCmdSendExt().	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
53517	Sometimes handler associated with adl_errSubscribe() function is not invoked on reception of error from OS.	OTHER	OTHER
77291	Airprime may reset due to a memory leak if adl_semSubscribe / adl_semUnsubscribe are called repeatedly.	OTHER	OAT
