I watch oFono chat with EM770W modem. If I restart ofonod after plugging
in the SIM card. We have:
ofonod[7871]: Pcui:< \r\n^SYSINFO:1,0,1,5,255,,4\r\n\r\nOK\r\n
ofonod[7871]: Pcui:> AT+CGMI\r
ofonod[7871]: Pcui:< \r\nhuawei\r\n\r\nOK\r\n
ofonod[7871]: Pcui:> AT+CGMM\r
ofonod[7871]: Pcui:< \r\nEM770W\r\n\r\nOK\r\n
ofonod[7871]: Pcui:> AT+CGMR\r
ofonod[7871]: Pcui:< \r\n11.126.08.01.00\r\n\r\nOK\r\n
ofonod[7871]: Pcui:> AT+CGSN\r
ofonod[7871]: Pcui:< \r\n357030020291346\r\n\r\nOK\r\n
ofonod[7871]: Pcui:< \r\n^BOOT:20291346,0,0,0,20\r\n
ofonod[7897]: Pcui:< \r\n^RSSI:15\r\n\r\n^SRVST:1\r\n
ofonod[7897]: Pcui:< \r\n^MODE:5,4\r\n
However, if I powered on modem with SIM card inserted, I have:
ofonod[7960]: Pcui:> AT+CGSN\r
ofonod[7960]: Pcui:< \r\n357030020291346\r\n\r\nOK\r\n
ofonod[7960]: Pcui:< \r\n^RSSI:1\r\n
ofonod[7960]: Pcui:< \r\n^BOOT:20291346,0,0,0,20\r\n
ofonod[7960]: Pcui:< \r\n^MODE:3,3\r\n\r\n^SIMST:1\r\n
ofonod[7960]: Pcui:> AT+CRSM=176,28590,0,0,1\r
ofonod[7960]: Pcui:< \r\n^SRVST:2\r\n\r\n^MODE:3,3\r\n
ofonod[7960]: Pcui:< \r\n+CRSM: 144,0,"03"\r\n\r\nOK\r\n
ofonod[7960]: drivers/atmodem/sim.c:at_crsm_read_cb() crsm_read_cb: 90, 00, 1
ofonod[7960]: Pcui:> AT+CPIN?\r
ofonod[7960]: Pcui:< \r\n+CPIN: READY\r\n\r\nOK\r\n
ofonod[7960]: drivers/atmodem/sim.c:at_cpin_cb() crsm_pin_cb: READY
So looks like Huawei modem doesn't send us ^SIMST unsolicited
notification in the first case.
