[PATCH 2/2] android/handsfree: Relax AT+CMER handling

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Spec says that HF may (not should) use AT+CMER=3,0,0,1 command to
activate indicators. Since AT+CMER has additional bfr parameter that
may be send by HF we should just skip it instead of failing.

This fix connection with Jaguar XF 2009 carkit.
