Hardware

T-Lora Pager with LR1121

Is this bug report about any UI component firmware like InkHUD or Meshtatic UI (MUI)?

  • Meshtastic UI aka MUI colorTFT
  • InkHUD ePaper
  • OLED slide UI on any display

Firmware Version

2.7.9.6f7149e (latest develop branch at time of writing)

Description

Upon booting T-Lora Pager I am faced with Critical fault #3:

Image

I am mostly able to scroll through the different tabs using the rotary encoder, though it often snaps back to the first tab which contains the critical fault message. It also sometimes snaps back to the messages tab.

Attempting to open the tab with the "wifi" icon crashes and reboots the device.

Pressing the spacebar and the "option?" key (the orange one in bottom left) will vibrate and snap back to the critical fault tab, from then on the rotary encoder stops working to switch tab making the device unusable until a reboot (though it keeps vibrating on press of spacebar and option keys).

I have tested 2.7.7.5ae4ff9, 2.7.8.a0c0388 and latest develop branch 2.7.9.6f7149e, all of these exhibit all these same exact issues. The only noticeable difference is latest develop branch is slightly better with rotary encoder switching tab, though still not great.

I assume this is related to my device using an LR1121 chip instead of an SX1262 chip

From what I could tell no one else has noticed these issues yet, and the more popular configurations seem with SX1262 (the shop page features the 3 base options, 433mhz / 868mhz / 915mhz, which are all SX1262, there is only one option for LR1121).

I am unable to confirm whether LoRa is even working as this is the only LoRa device I have and no one I know close to me owns a Meshtastic node. I bought the device to get into Meshtastic and use it at cons, and possibly discover other nodes nearby, so yeah I am unable to tell if it's working as I don't have a reference point to compare with.
