Orange PI 2G IOT GSM modem port in Ubuntu

drazvan

Hello,

Has anyone been able to talk to the GSM/GPRS modem on the 2G IOT from Ubuntu? I see 3 serial ports (ttyS0 (console), ttyS1 and ttyS2) but none of them respond to any AT commands. Does the modem need to be enabled via GPIO somehow?

Thank you,
Razvan

See http://surfero.blogspot.com.es/2 ... a-orange-pi-2g.html (in Spanish) for how to make it work with wvdial. It worked fine for me.

Try to cahnge this : Init2 = AT + CGDCONT = 1, "IP", "wap.tracfone", "", 0,0  ---> Init2 = AT+CGDCONT=1,"IP","wap.tracfone","", 0,0
simply remove spaces. I've received error 58 when wvdial send not supported/syntax correct AT command.
