Client for POC devices?

[rubeycubey]

Context

There are numerous walkie talkie-like devices coming out of China that seem to operate over LTE Cat-M using cheap IoT SIM plans to provide essentially global walkie talkie coverage. Some appear to be based on the Zello platform while others seem to based on the Global-PTT platform. The devices seem to be based on Linux/Android. Search AliExpress for '4G walkie talkie ' to see examples of the devices.

A mumble client that works on these would seem to be a great opportunity for cheap, open source hand-held comms.

I'm afraid I don't know much else about the devices yet but have ordered a couple to test.

Edit: found a video of a guy who seems to have hacked one of the devices:

If you can get Qt (or compile Qt) for such a device, the official Mumble client should be able to run on it (it probably needs to be specifically compiled for this platform though).

However, I assume that the dimensions of these devices are closer to a phone so our desktop client probably doesn't offer the best UX there.

If they are running Android, installing Mumla is likely a better option.

We use mumla for android and mumble for pc/ios - radiolink is made with talkkonnect thats also a nice option ;) compared to zello etc. so a poc device solution is possible just make sure they have a tochscreen because some poc radio have wred mapping of keyes.
