Modem wakes for incoming call, but too slow to answer the call

[dchang0]

Hi, everyone--

For the first time, I've got two cellular phone lines and am able to play more with the PinePhone Pro.

I called the PPP running Mobian, and it woke properly from sleep, and the modem also woke properly, but it wakes so slowly that the incoming call has gone to voicemail without ever ringing. It does say "Missed call" on the lock screen afterward.

If the PPP is already awake, it rings and receives the call just fine, so all I need to figure out is how to get the modem to wake fast enough to receive the call.

Any tips are appreciated. I plan on updating Mobian to the latest package versions tomorrow. It's been many months since I last powered on the PPP, so whatever it is running now is old.

I also will apply any modem firmware updates if there are any newer ones.

If updating is a bad idea, please let me know.

Thanks!

i don't usually use suspend. but i tested sending sms mesaage to suspended pp pro with mobian. it waked up quickly and received sms. but modemmanager crashed afterwards. mobian is recently updated trixie.

i probably need to make further tests.

updating firmware is tricky question. do you use https://github.com/the-modem-distro/pinephone_modem_sdk or stock https://github.com/Biktorgj/quectel_eg25_recovery ?

if stock, i don't recommend 30.20x.xx.xxx series. 30.007.30.007 is the latest i would suggest.

if sdk, latest is the best, but you have to choose appropriate adsp image.

i installed this version https://github.com/Biktorgj/quectel_eg25...203.30.203 one of my pp regular without major issues. still no recommendations for 30.20x series.

Thanks for the reply. I am on bookworm now and am having a tough time updating to whatever is current. I'll get back to you on this.

As for the modem, I think I went with the latest Biktorgj firmware at the time. There is probably something much newer right now. Thanks for the tip about not going to 30.20x on stock, and I will try the Biktorgj version you recommend.
