Howto address Buttons on V1.2 ESP32 Lora Modul Ipex GPS-NEO-M8N SX1278 433MHz and devel20240316-B17-full.bin?

[georgjorge]

The board has three buttons: RST, GPIO 38 and Power. No matter how I set Button input and Button 2 input the only reaction I get is via Button Power to scan from one display to the next. I am not able to get the reaction described under the Control Menu. That means there is no way to get the frequency screen by medium keypress.
Any idea?

This should work but has never been tested.
The V1.2 (assume this is aT-Beam Board) uses a different PMU chip, and the power button is handled via the PMU chip.
I will have a look later this week.

Yes, it is a T-Beam Board V1.2 ESP32 Lora Modul.

I compiled the devel20240419 and on my TTGO-T-Beam T22 V1.1 and when set the screen saver I am not able to wake up the display using any button, the screen remain blank. Left comment on the topic in Issues.

What time out do you use? It is working fine for me, but you have to use a screen saver time out larger than 1 second (otherwise it will remain blank, as the display is updated only once per second, so if you have something like "1" or "11" in the config, this is 0 or 1 seconds, so it will not work).

[dl9rdz]

Maybe to explain better: config value:
1 => display is always off
2 => display is always off if no signal is received
and then e.g.
51 => display goes off after 5 seconds

The buttons seem to work as intended also on the T-Beam V1.2
(https://github.com/dl9rdz/rdz_ttgo_sonde/wiki/Interactive-control)

In the default configuration, the power button (the one of the left) is used as button 2 - which means that only a short keypress has an assigned function, the medium keypress is detected correctly (but in the standard screens config no action is associated with button 2 medium keypress).
The middle button - button 1 - works as described in the interactive control, allowing you to switch to WiFi scan, spectrum display, next frequency, and back to frequency scan.
