Brightness slider activates on TTGO-LoRa32-V2.1 with serial Puttty connection.

[thomslik]

Anytime TTGO-LoRa32-V2.1 is connected with a serial connection with Putty or the Python API, the brightness slider activates and repeatedly cycles from low to high. Attempting to edit the screen by pulling the GPIO0 low to ground does nothing. Ending the Putty or Python session returns the unit to normal operation.

This may not be an appropriate issue, as TTGO-LoRa32-V2 is listed as supported, but no mention of V2.1. If so, sorry , Please ignore and close.

I guess the issue can be closed https://meshtastic.discourse.group/t/alpha-tester-thread-please-try-device-code-0-7-11/298/179?u=ahvzy2g ?

This is a totally unrelated issue. It has nothing to do with the T-Beams. It seems to be caused by different pin outs between the TTGO-LoRa32-V2.1 and V2.0 and only occurs with a serial connection.

could you verify that this is the version you have https://github.com/LilyGO/TTGO-LoRa32-V2.1 , I will try to add support for it.

oh yes good point. slider going up endlessly means the GPIO assignment for the button on the lora32-v2.1 is wrong.

@thomslik please test #274 and let me know if it works

Yes. That is the version I have.

Sorry for my ignorance, but where do I find the bin to try?
I tried to build from your issue 274 branch, using the build instructions. But got an Error: Unknown environment names 'ttgo-lora32-v2-1-16'. Valid names are....... with only the two old versions of ttgo-lora32 included in the list.

[thomslik]

Updated earlier reply, to include tried to build.

[aHVzY2g]

@thomslik I will send you a bin asap

[aHVzY2g]

Here you go I have two separate bin files. Please test both an tell me if they work. Before each flash use the esp download tool to erase the flash of your board.

Thanks. Both versions still do the same. The unit appears to be working fine until the serial connection. Then the same problem with the brightness slider.
