The issue is here:
ofonod[2536]: Aux: > AT+CGREG=?\r
ofonod[2536]: Aux: < \r\nOK\r\n
ofonod[2536]: GPRS not supported on this device
The correct response to this query according to 27.007 is of the
following form:
+CREG=?
+CREG: (list of supported <n>s)
Since the hardware simply returns 'OK' (which is not valid according to
the spec) we do not know what modes (1 vs 2) of CREG it supports. Hence
we have no idea how to drive this hardware. This can be fixed via a
driver quirk, but we need to know whether e.g. AT+CGREG=2 works...
ofonod[2536]: src/gprs.c:gprs_remove() atom: 0x8f935e0
ofonod[2536]: Aux: > AT+CREG=?\r
ofonod[2536]: Aux: < \r\nOK\r\n
ofonod[2536]: Unable to initialize Network Registration
Same issue as above... The response to +CREG=? is not valid.
Regards,
-Denis
