Hi,
Does ofono have a way to handle lacking OK/error messages? I seems like
my modem (Quectel M95) is buggy when it comes to unsolicited indications
and (as far as I have seen) SIM commands:
> AT+CRSM=178,28614,3,4,8
< +CRSM: 144,0,"FFFFFFFFFFFFFFFF"
< OK
> AT+CRSM=178,28614,4,4,8
< Call Ready
< +CREG: 5,"0119","04EA"
The "Call Ready" indication causes a lacking "OK" from the preceding
"AT+CRSM" command. This has happened with other CRSM commands, and can
also be caused by an unsolicited +CREG indication.
I guess one way handle it, is to to glue op the URC listeners to peek
into the AT command queue and check if a command is pending for
OK/errors, and retry it if so.
But that could cause unexpected side effects depending on the retried
command...
