⚠️ Check that radio.rxgain(on) and flood.advert.base (0.308) are set correctly after flashing! ⚠️
This build is based on official MeshCore 1.15.0 dev branch (as of 25-May-2026 and additionally includes the following unmerged upstream PRs/changes:
- PR2553: Limit flood advert packet forwarding -->
set flood.advert.base 0...1(0: no flood adv. forwarding, 0.308: default, 1: all flood adv. forwarding) - PR1810: Allow direct message paths when denyf * is set
- :new: PR1727: Use hardware channel activity detection for checking interference --> Use
set int.thresh 1to activate hw based channel activity detection. - :new: PR2377: Disable NRF52 undervoltage bootlock feature
- Flood adverts are disabled (flood.advert.interval set to 0) by default
- :new: modified PR1810 to not block flood adverts but only
PAYLOADTYPEGRPTXTandPAYLOADTYPEGRPDATAso that some limited flood advert distribution can be managed via PR2553 to support e.g. observer maps.
- Based on
devv1.15.0 as of 25-May-2026

Quick Usage
Repeaters / Room servers
All PowerSaving features are disabled by default and persisted across reboots. PowerSaving:powersaving on, powersaving off and powersaving
GPS PowerSaving: powersaving on then gps on and gps.
RX PowerSaving: set radio.rxps balanced and get radio.rxps. Repeaters with RXPS enabled are less affected by noises from cell towers. It may due to LoRa RX only wakes up periodically.
Added Battery voltage and PowerSaving status to repeater OLED
Set dark theme for Heltec T096.
BLE / USB Companions
All PowerSaving features are enabled by default. GPS PowerSaving is enabled when you enable Position in MeshCore app. Added uptime for all companions. Set dark theme for Heltec T096.Complete Guides in Wiki
