Got tired of waiting for #1584 and #1264 to fix the issues so I created this PR from the information on #1584. I decided to use @oltaco suggestion as it looks cleaner. No need to define ADC_MULTIPLIER for heltec_v3 and heltec_tracker tho, as they will use the default value.

Trahomich pushed a commit to Trahomich/MeshCore that referenced this pull request Mar 31, 2026
- Extract hardcoded ADC multiplier (5.42) into ADC_MULTIPLIER macro
- Add ADC_MULTIPLIER=8.4 for Heltec Wireless Paper variant
- Default ADC_MULTIPLIER=5.42 for Heltec V3 (unchanged behavior)

Where can I download a beta of this to test this out on a device?

@liamcottle Where can I download a firmware file for the paper to test this out? Nightly build from brazio would have it included? https://files.brazio.org/meshcore/nightly/companion/

Yep, have checked and the nightly files at the link you pasted include PR #2164.

If you're updating from older firmware, you'll want the one without merged in the name:

  • Heltec_Wireless_Paper_companion_radio_ble-nightly-9f680d1.bin

If you want to erase flash and start fresh, you'll want the merged bin:

  • Heltec_Wireless_Paper_companion_radio_ble-nightly-9f680d1-merged.bin
