Then using the n_gsm ts 27.010 uart mux, I dial:
./ngsm-rw 1 "AT+CFUN=1" # connect to network U0001+CFUN:OK ./ngsm-rw 2 "AT+CMUT=0" # unmute speaker over ch2, do this over qmi? U0001+CMUT:OK ./ngsm-rw 1 "ATD#123" # dial number U0001D:OK
And I do hear a voice talking over the speakerphone :) Sorry have not tested the mic yet..
Hehe, ok, that's fun! I don't need +CMUT=0. It gave me error but then the call worked, anyway... (I'm working with ttyUSB4).
Oh interesting. So maybe Android is doing AT+CMUT=0 for some other modems and it's not really needed? Or you have settings preserved from warm boot from Android?
No idea. But I booted from recovery, and I had to power up modem using +CFUN...
I did not have any luck with ttyUSB4 last night. Did you dial with ATD123; or ATD123? So is the semicolon really needed?
AT+CFUN=1 OK ATD800123456 NO CARRIER ATD800123456; OK
I seem to need semicolon. And yes, I tried again after the call. Still says no carrier.
Hmm. And when calling test number, the modem failed:

That one will be fun to debug, I'm afraid. (Or does the message at 495.496032 mean that we turned it off?)
