[RT3S GPS] PTT Latch

[IU4TEG]

Hi, thank you for everything you do on this free project.
I use a Retevis RT3S GPS, latest "Release Candidate 2 Version 2024 08 03" onboard.

I noticed that when i set Ptt Latch option in the radio menu to On it doesn't work. Ptt button operates normally. Tried also to reflash but no success, I suppose I had the same trouble with one or two previous betas, but initially it worked fine, one touch for tx on and one again for tx off...

Am I doing something wrong or is an issue?
I was just curious, it's not an essential feature for me.

I also noticed that the green led stopped working, I suppose it is a cold soldering issue in this case, because also in DFU mode the led doesn't blink (only red blinks).

73 and many thanks.
Fabio.

Just tested the PTT latch on UV380 and its working fine.

PTT latch requires a TOT to work.

F1RMB you're right.
I read the whole manual months ago and didn't remember it.
My fault, I apologize.
