Nz region sf16 preset by NomDeTom · Pull Request #11009 · meshtastic/firmware

NomDeTom · 2026-07-14T11:09:21Z

Adds a new region to allow the ShortFast preset to be the default in New Zealand from the start, rather than LongFast as is the default for the ANZ region.

Requires protobufs: meshtastic/protobufs#985

Summary by CodeRabbit

New Features
- Added support for the New Zealand 915 MHz LoRa regulatory region, covering the 915–928 MHz frequency band.
- The LoRa region picker and related menu now include “NZ 915”.
Improvements
- Updated the radio region configuration to use the latest regional definitions and default preset behavior.

New Zealand's mesh standard is ShortFast on frequency slot 16, which lands on 918.875 MHz in the 915-928 MHz ANZ band. Set the region's default preset to SHORT_FAST and pin the default frequency slot with an explicit overrideSlot of 16 instead of the channel-name hash.

Revert the ANZ region-table change: ANZ is shared with Australia (and historically Brazil), so changing its default preset there would alter defaults for everyone, not just New Zealand. Instead, bake the NZ community defaults into firmware built from this repo via userPrefs.jsonc: region ANZ and modem preset SHORT_FAST. No frequency-slot override is needed - the default channel name ("ShortFast") hashes to slot 16, which is 918.875 MHz, the NZ mesh standard.

.gitmodules now tracks NomDeTom/MeshtasticProtobufs @ nz-sf, rebased onto upstream meshtastic/protobufs master (adds NZ_924 as a new RegionCode value, additive/non-breaking). Regenerated the nanopb C sources from that commit, which also incidentally picks up the MEDIUM_TURBO modem preset added upstream in the same rebase window.

Same 915-928 MHz band and PROFILE_STD as ANZ, but defaults to SHORT_FAST instead of LONG_FAST. Frequency slot is left on the default channel-name hash (overrideSlot 0), which for the "ShortFast" channel name lands on slot 16 = 918.875 MHz, the New Zealand mesh standard.
