Thanks for your comment!
I can connect to my APN using qmicli in buildroot, but I haven’t managed to make it work with vintage_net_qmi yet. Due to the fact it’s dual sim, you also need to run a couple of commands before you can use the modem. PostmarketOS has a service that does all that and I just copy pasted it in my buildroot port. It looks at the two SIM card slots, checks which one has a card inserted, then reconfigures the modem to use that one.
To support cellular in the Nerves system, it “just” means translating that service into Elixir code, most probably wrapping qmicli itself and providing a nice Elixir library to include in your firmware. I’ll try to get it done during the next weeks.
It’s my first time using scenic but here you go:
There is a drm device exposed so anything using this will work. Wpewebkit or similar should work out of the box, and since I’ve been using flutter with Nerves on some other projects, it might be a good thing to try here as well.
I’d say the very first step is to install PostmarketOS on it by following their doc on the wiki for your device.
You can install PostmarketOS in console mode (no GUI), and then you basically have Alpine Linux, so if you only aim to get an OTP app running on it, you should already be able to install OTP and Elixir on Alpine and have what you want.
To get Nerves on it requires more digging, and the first step is to get the kernel config and firmware for your device. All the work on the SOC present on this phone seems to be happening here so it seems promising. Digging into the PostmarketOS Alpine packages for your device will give you all the information you need to translate it into a buildroot port.
But first things first, make sure you can run PostmarketOS on it.
ended up a win because I got more hardware pictures.
