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=3D2 works... ofonod[2536]: src/gprs.c:gprs_remove() atom: 0x8f935e0 ofonod[2536]: Aux: > AT+CREG=3D?\r ofonod[2536]: Aux: < \r\nOK\r\n ofonod[2536]: Unable to initialize Network Registration Same issue as above... The response to +CREG=3D? is not valid. Regards, -Denis --===============6593633752187303905==--
