Hi Manuel!
I was just wondering the other day if you have any ideas for a sym key solution? I miss the tab and some extra shortcuts.
The extio solution for me was a low level wrapper in the src/io (newly created) folder.

The key in the lower left corner can be used as ALT key. I think it's code 21.

Well yes, either alt or sym. (I said it wrong above but you got the point).
Either we can't use symbols (the colored captions) or shortcuts (tab, backlight, ad-hoc ping, control arrows, GPS toggle... ) 🙁

But the display support is very good to now included in the original code. 😉
I also have T-display-s3 pro LR1121. I also have a ST7796 shield for the t-beam board.
Although I've been using it for a while now I'm having some problems. I can't compile anything that uses lovyangfx. 🙁

This looks good, but I just wanted to call out that the fact that any movement of the jog wheel immediately triggers the canned message dialog, which seems problematic. Particularly because the "press button" of that jog-wheel is extremely sensitive on my device.

You may want to consider fixing that.

This is externally managed by the canned message module.
You can disable the button function using the App by setting canned message module.inputbroker_pin_press 0

Okay, but why aren't these settings baked into the variant?

[mverch67]

Because there's no need if these can be changed at runtime in a flexible manner.

I would imagine that variants should be configured to more or less "work out of the box", but okay.

Incidentally, the GPS is completely INOP on this build, so the checkbox on GPS M10Q is inaccurate.

GPS is working fine here. The Antenna is abysmal, takes a long time and clear sky for an initial fix.

Huh, I'll give it another try.

Hi there, thank you very much for the Pager support. I managed to build and run it, but how can I navigate through the menu?

[mverch67]

Hi there, thank you very much for the Pager support. I managed to build and run it, but how can I navigate through the menu?

You can use:

1. single button (boot button): short / long press
2. boot button + back key (backwards / escape)
3. rotary wheel: select canned message or up/down in menus, short/long press

Thank you, one more:

is there an option to turn ON/OFF keyboard backlight?

[mverch67]

is there an option to turn ON/OFF keyboard backlight?

You can toggle the keyboard backlight in two intensities using SYM + SPACE

[LOCOSP]

Is there any newer build, coz it's not working for me SYM is the very bottom left button? UPDATE: Never asked :), just pulled all new commits and it's working - Thank You !!!

Hey. I just ordered this device. How do i build the firmware for it?

You may want to consider fixing that.

I've implemented a fsm based bounce-free rotary encoder driver. It will replace the updown encoder implementation which is completely useless for T-LoRa Pager. So to activate it either do a factory reset or enable the (new) updown encoder:

meshtastic --set canned_message.rotary1_enabled FALSE --set canned_message.updown1_enabled TRUE

The wheel press button activates the popup menu on a screen which options can then be selected using the wheel.
Note: turning the wheel needs to pass all states of the state machine to detect the rotation direction. Turning it too fast does nothing because steps of the state machine would be skipped (which is not allowed).

Even though the encoder pin processing is now based on polling (instead of interrupts) there is no more false direction detection. Now it's 100% accurate.

Edit:
If you want the rotary wheel to navigate through the screens instead of the menu options then you can set the following:
meshtastic --set canned_message.inputbroker_event_cw LEFT --set canned_message.inputbroker_event_ccw RIGHT
