SlunseCore Room Server Firmware v1.17.1

SlunseCore room server builds track MeshCore v1.17.1 with SlunseCore custom features preserved.

Official upstream release: MeshCore v1.17.1 — 14 Aug 2026

SlunseCore changes

• SlunseCore integration branch merged with upstream v1.17.1; no additional room-server-specific UI changes in this release. R1 Neo and Minewsemi ME25LS01 room-server builds now use upstream's own v1.17.1 build fixes directly rather than SlunseCore's earlier ad-hoc patches for the same gaps.

Official MeshCore v1.17.1 release notes

The following is condensed from the official MeshCore v1.17.1 announcement (14 Aug 2026). This is a point release focused on fixes on top of v1.17.0.

New Features

• New radio.fem.rxgain / radio.fem.txgain CLI commands (txgain support currently limited to Station G3)
• Missing KISS radio roles added, plus KISS radio build support

Enhancements

• LR2021 preamble-detection and IRQ-timeout logic updates
• nRF52 CC310 optimization: nRFCrypto now initialized only once
• Improved RNG: combined entropy from radio + CC310 sources

Critical Fixes

• Heltec T096 transmit failure, caused by an out-of-bounds PIN_SPI1_MISO configuration
• T-Echo Lite pin alignment and TCXO voltage adjustment (3.0V), matching revised Lilygo schematics
• R1 Neo and Minewsemi ME25LS01 build issues
• Rx boosted gain no longer resets to the compiled-in default after an AGC reset
• Multiple unused-pin corrections across nRF52 boards

FEM Configuration Note

radio.fem.rxgain was not being persisted properly in earlier versions. Administrators with FEM-equipped devices should verify their FEM gain settings after updating.
