Ok we have tested with one friend so 2 people max and it didn't work in SimCox connection mode but in a server group with a hosted IP address. Except that from time to time certain radio messages could not be heard by the other person.

Here are our two logs:

Hi Mute,

The logs look like everything is working correctly.

My first thoughts are that it's something to do with the UDP port, as I see that there isn't a port forward (different internal and external ports).

I'll have a look and give the code a once over to check that it's advertising the correct connection port to other clients in SCX mode. I should have time later today.

I may also add extra info to the log showing when connections are being attempted.

You may lose the occasional voice message as the app is to mimic a VHF/UHF radio.

So I've deliberately built it to not be as clear as Skype or Discord for example.

That said..

Comms should be readable and able to be understood, just not crystal clear.

I've had a look over the code and can't see anything obvious, as to why Group mode would work but not SCX mode.

None the less, I have made some very small edits to make sure that things are doing what they should.

 I have also added to the log when the client attempts to connect to another client.

This will prove that your client is getting the correct details to connect to somebody else.

If the other clients connection details are correct in the log and you still don't connect, this would point to the connection being blocked by something. A firewall for example.

I hope that helps?

Ok thank you very much Roo, we will try as soon as possible and i call you back 😉
