Hello, I have noticed a difference of ofono on startup. If the PIN number is not required, the daemon never gets past CRSM query, and the remaining interfaces are not added. But if the PIN number has not been entered, things work as they should. Scenario 1: The SIM card needs the PIN number to work. ofonod[8203]: attr_cb got result: 1 ofonod[8203]: Final response: OK ofonod[8203]: Response line: SIEMENS ofonod[8203]: at_cpin_cb got result: 1 ofonod[8203]: Final response: OK ofonod[8203]: Response line: +CPIN: SIM PIN ofonod[8203]: crsm_pin_cb: SIM PIN ofonod[8203]: at_crsm_info_cb got result: 0 ofonod[8203]: Final response: ERROR ofonod[8203]: attr_cb got result: 1 ofonod[8203]: Final response: OK ofonod[8203]: Response line: MC75 ofonod[8203]: at_crsm_info_cb got result: 0 ofonod[8203]: Final response: ERROR ofonod[8203]: attr_cb got result: 1 ofonod[8203]: Final response: OK ofonod[8203]: Response line: REVISION 03.010 ofonod[8203]: at_crsm_info_cb got result: 0 ofonod[8203]: Final response: ERROR ofonod[8203]: src/voicecall.c:ecc_read_cb() 0 ofonod[8203]: attr_cb got result: 1 ofonod[8203]: Final response: OK ofonod[8203]: Response line: 35**** ofonod[8203]: at_lock_unlock_cb got result: 1 ofonod[8203]: Final response: OK ofonod[8203]: at_cpin_cb got result: 1 ofonod[8203]: Final response: OK ofonod[8203]: Response line: +CPIN: READY ofonod[8203]: crsm_pin_cb: READY Scenario 2: The daemon has been restarted (following correct SIM PIN number insertion). ofonod[16456]: attr_cb got result: 1 ofonod[16456]: Final response: OK ofonod[16456]: Response line: SIEMENS ofonod[16456]: at_cpin_cb got result: 1 ofonod[16456]: Final response: OK ofonod[16456]: Response line: +CPIN: READY ofonod[16456]: crsm_pin_cb: READY Thanks, Ryan
