⚠️ 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 1 to activate hw based channel activity detection.
• :new: PR2377: Disable NRF52 undervoltage bootlock feature

Additional changes:

• Flood adverts are disabled (flood.advert.interval set to 0) by default
• :new: modified PR1810 to not block flood adverts but only PAYLOADTYPEGRPTXT and PAYLOADTYPEGRPDATA so that some limited flood advert distribution can be managed via PR2553 to support e.g. observer maps.

Changelog:

• Based on dev v1.15.0 as of 25-May-2026

This is for all NRF52-based repeaters and ESP32-based repeaters: 6mA power consumption for ALL NRF52-based repeaters and 10mA power consumption for ALL ESP32-based repeaters

• [Production] For ESP32-based repeaters, the firmware is very stable and in production. We will improve the timedrift for ESP32-based repeaters in the next version.


• [Beta] For NRF52-based repeaters, the firmware is newly released. Please test it a while with easy to access repeaters.


• We will push this PowerSaving version to MeshCore github within 7 days. Usually, we will listen for your feedback before we push to MeshCore github.

NRF52-based repeater at 6mA and ESP32-based repeater at 10mA

IMPORTANT:

• On CLI, you need to type "powersaving on" ONCE to achieve 10mA power consumption. The setting will persist even after reboot.


• Powersaving (if enabled) will start 2 minutes since boot.


• If you enable OTA via start ota in CLI, then powersaving will have no effect.

New features:

• Improved PowerSaving for ALL NRF52-based repeaters from 8.5mA down to 6mA. Initially, NRF52 consumes 12mA down to 8.5mA (PowerSaving 9+) and now 6mA (PowerSaving 11).

Instruction:

• Instruction to Flash Custom Firmware


• Please read the instruction in Add sensors to repeaters

Videos:
This is a RAK4631 repeater with PowerSaving in action: Sleep at 6mA, wakeup when a LoRa packet comes, process it, wake up for 5s and go to sleep again.
