Making phone calls

[colin hodsdon]

I am trying to get the phone part of the PinePhone working, what I wrote here is what I tried, however I did not succeed yet and I hope you can help me with it.

I use this as a guideline:

https://megous.com/dl/tmp/modem.txt

For the mixer it is written:

1) alsamixer

- set "Line Out Source" to "Mono Differential"
- Unmute "AIF1 Slot 0 Digital DAC"
- (optional) unmute the microphone / mute loudpeaker

And I tried to do that in bash

Code:

# Enable audio
sudo modprobe snd_soc_simple_amplifier
sudo modprobe snd_soc_simple_card_utils

# Unmute audio
amixer -c 0 set 'AIF1 Slot 0 Digital DAC' unmute

# Mute speaker (audio will loop otherwise trough the speaker and mic, terrible noise!!)
amixer -c 0 set 'Line Out' mute

# Unmute the ear speaker? (not sure)
amixer -c 0 set 'Earpiece' unmute

# Open microphone
amixer -c 0 set 'Mic1' unmute

# Set volume
amixer sset 'Line Out'  0%
amixer sset 'Earpiece' 100%
amixer sset 'Mic1' 100%

# Set mono
amixer sset 'Line Out Source' 'Mono Differential'

Next is how to send AT commands to the modem?

If I run the following command I get the modem device name and information:

Code:

/usr/share/ofono/scripts/list-modems

And I want to run something like:

Code:

sudo echo "AT+QTTS=2,\"Welcome to use the module of QUECTEL" > /quectelqmi_0

But /quectelqmi_0 needs do be a device file and it is not I guess.

Who want to help me out here?

Thank you in advance!

I found two lines on another part of the forums that seem to work for me as far as the modem goes.
sudo /usr/share/ofono/scripts/enable-modem
sudo /usr/share/ofono/scripts/online-modem

After you type each and hit enter, you will see a message about the modem, and after the second line you should see the network symbol show up in the notifications bar (assuming you have a SIM card in place.)

Made my first call today, found a carrier that works for the PinePhone (TracPhone, using the ATT SIM card), got the SIM activated, used the two script lines to enable the modem, and had the network symbol show up in the notification bar.  Successfully called my Verizon phone from my PinePhone.  Only problem is that the PinePhone has no sound, so I cannot receive calls.  But Texting works!

Script lines for enabling the modem.  (Lucas posted these elsewhere in the forums.)
sudo /usr/share/ofono/scripts/enable-modem
sudo /usr/share/ofono/scripts/online-modem
