ofonod: < AT+CPIN?
ofonod: drivers/atmodem/sim.c:at_cpin_cb() crsm_pin_cb: READY
ofonod: < AT+CPINR
ofonod: < AT+CRSM=192,28590,0,0,255
ofonod:Querying remaining pin retries failed
ofonod: < AT+CRSM=192,28589,0,0,255
Once this happens(ofono stop after AT+CRSM), I can only list the modem
with the feature "sim"
It is hard to tell from your log what is going on. Is your oFono
modified in some way? The AT command logging should print commands
sent, echo (if any) and command responses. I'm not seeing that here.
Do you get a response to the last CRSM command sent? If not, then
likely the modem crashed. The two CRSM commands you see above are
querying EFad and EFphase. Right after there should be some more EFs
being read followed by reading of the IMSI (+CIMI)
Here is my question,
1, why does it happen randomly?
2, what does "Querying remaining pin retries failed" mean?
is showing up even when the ofono is working fine.
It just means that the sim atom driver does not implement this
functionality. It should probably be changed from a warning to a debug
3, sometimes all the module had been loaded, but the connection
Impossible to tell without a log.
