'''*In order to connect to the GSM network, you need to connect a modem in the J1100 connector and insert a SIM card in J1102. Then, when powering up the board, kernel should recognise the modem and list it under construction'''/dev/ as a list of ttyUSB devices. We are using a Quectel UC20 Modem, in this case.*From userspace, we must use a serial console to communicate with the modem via AT commands:<pre>microcom -s 115200 /dev/ttyUSB2</pre>*Once the serial console is set, we can interact with the modem. In this example, we check the modem status, ask if the SIM card is activated or needs a pin code to be entered, enter the pin number and check signal level:<pre>ATOKAT+CPIN?+CPIN: SIM PIN
OK
AT+CPIN=1234
OK
 
+CPIN: READY
 
+QUSIM: 1
 
+QIND: SMS DONE
 
+QIND: PB DONE
AT+CSQ
+CSQ: 99,99
 
OK</pre>
 
''Where '''1234''' is your SIM card's pin number.''
*+CSQ: 99,99 denotes an undetectable signal. If we use an antenna, we can get better coverage. [http://m2msupport.net/m2msupport/atcsq-signal-quality/ Here] you can find a table with the relationship between CSQ value and dBm, as well as a guide to recognise how strong a signal level is.
*You can find more Quectel UC20 compatible AT commands [http://www.soyter.pl/system/files/UC20_AT_Commands_Manual_V1.0.pdf here].
