MeshCore 1.14.0: CLI Additions, Routing Improvements and Power Fixes

Released on March 6, 2026, MeshCore firmware version 1.14.0 brings a focused set of improvements across the room-server, repeater, and companion builds. The update adds four new CLI commands, strengthens mesh routing with multibyte path hashing and loop detection, refines the radio AGC reset behavior, and addresses power issues on three specific hardware platforms.

Four New CLI Commands

The standout addition is discover.neighbors, which queries directly reachable nodes in the mesh — a handy tool for quick topology checks without needing the companion app. The other three commands support the new routing and diagnostics features introduced in this release:

CLI

# Check installed bootloader version
get bootloader.ver

# Enable loop detection
set loop.detect on

# Query or set the path hash mode
get path.hash.mode
set path.hash.mode 2

Multibyte Path Hash and Loop Detection

Path hashing compresses routing path information into a short hash value, helping nodes identify duplicate packets and avoid forwarding loops. The new multibyte path hash support increases the hash space, which significantly reduces the chance of hash collisions in larger, denser networks. Combined with the configurable loop detection (loop.detect), this gives node operators more control over routing stability.

Reworked AGC Reset

AGC (Automatic Gain Control) continuously adjusts the receiver's sensitivity to handle varying signal strengths. In some situations — particularly after strong interference — the AGC could get stuck in an incorrect state, degrading receive performance. The reworked reset implementation in 1.14.0 ensures the radio recovers more reliably after such events.

Power Fixes: Heltec V4, Heltec Tracker V2, RAK3401

Three boards receive hardware-specific power improvements in this release. The Heltec V4 and Heltec Tracker V2 both had power management issues that could cause unexpectedly high current draw — these are resolved with targeted fixes. The RAK3401 gets power optimisations focused on reducing idle current consumption, which is especially relevant for battery-powered remote nodes running unattended for extended periods.
