Hardware

T-Echo

Firmware Version

2.3.4.a4c22321

Description

Double press on T-echo is assigned to two different actions:

• Toggle backlight
• Send ad-hoc ping

Relevant log output

No response

Perhaps the capacitive touch button on top would be better suited to the backlight toggle, since the double press ad-hoc ping is available on any platform with a user button

That's certainly an idea that I can look into. I do remember hearing that there are some design issues with the touch button: that it is triggered every time a LoRa packet is transmitted, but I haven't confirmed this for myself yet.

the top touch button doesnt work for me at all.

@Nikto655 Currently it doesn't do very much.

After a bit or experimentation, I think the most user friendly option is to use the touch button as a modifier.

Double press user button to send adhoc ping
Hold touch button + double press user button to toggle backlight.

This both aligns with standard meshtastic behavior, and remains somewhat familiar to T-Echo users.

I should have a pull request for this (and a few other related fixes) shortly.

@todd-herbert Can we exclude the touch button completely please. the alternate cases i design for the t-echo are not compatible with it and ive pealed it off completely since all it did before was refresh the screen. Needing the touch button over the regular user buttons severely limits future designs. Can i ask we add 4x user button push for the t-echo light. The change you are proposing would render the light with alternate cases useless.
