Internal GPS not working in EdgeTX 2.11.1

Open ojoojoo opened this issue 7 months ago • 9 comments

Is there an existing issue for this problem?

  • [x] I have searched the existing issues

What part of EdgeTX is the focus of this bug?

Transmitter firmware

Current Behavior

I connected a M8Q-5883 M8 GPS on the AUX1 port of my Radiomaster TX16S after I configured the GPS in Ucenter on NMEA output only and the UART1 on 9600-8-N-1. Under OPTS: I have internalgps. I enabled the GPS in the transmitter under hardware and started the Internal GPS widget. I don't see any discovery's under Telemetry. I don't see the GPS communicating with the transmitter, RX and TX are correctly connecter (RX=>TX and TX=>RX)

Expected Behavior

I expect to read the GPS output on the screen, I get nothing at all.

Steps To Reproduce

See the text at currect behaviour.

Version

2.11.1

Oh yes this is really helpfull...

As a reminder, this is not an end user support tool, just a bug handling tool, and what you report doesn't seem to be a bug...

So what are your settings used, what type of GPS, did you test this on 2.11.1, because date says 13 apr. what are the uart settings etc. ? Just saying that it is working doesn't help anybody. It doesn't work in my setup with the settings I posted, and I don't think I did something wrong in my setup so for me it's a bug.

Tested today, (radio date and time is wrong), 2.11.1 using ublox m8n gps that was used during this feature development

Well I can confirm the GPS is working on a Radiomaster TX16S MKII EdgeTX 2.10.1, but not working on a Radiomaster TX16S MKI EdgeTX 2.11.1. The only two possibilities remain: A) The UART on the Radiomaster TX16S MKI EdgeTX 2.11.1 is defective (From factory, never used) B) There is a bug specific for the Radiomaster TX16S MKI EdgeTX 2.11.1

When I connect a FTDI adapter to the UART (AUX1) and select "Telem Mirror" I see data on my terminal, so this can mean that the UART is OK:

Mk2 and mk1 are electrically 100% identical and therefore share the same firmware

3djc avatar May 25 '25 15:05 3djc

Than the RX of the UART can be defective, I don't know how to test this quick
