Meshtastic adds Indonesia to its regional configuration docs

Meshtastic has added Indonesia to its regional configuration docs, and that tiny documentation change removes a big early hurdle for people bringing new nodes online. The current region-by-country table now lists Indonesia as SG_923, giving local builders a concrete default instead of a guess.

That matters because Meshtastic’s region setting is not cosmetic. The initial configuration docs say it controls which frequency range a device uses, and it should match the user’s regional location. Pick the wrong region and you can end up with a mesh that behaves badly long before anyone realizes the problem is the setup, not the hardware. In a system built on affordable, low-power devices that run off-grid and without cell service, that first choice sets the tone for everything that follows.

The new Indonesia entry also cuts through a problem the community had already been flagging. On February 28, an Indonesian GitHub issue asked for a dedicated Indonesia region, ID_923, and noted that local users were already running SG_923. A separate firmware issue from about 1.6 years ago said Indonesian users could not find a clear official reference for the right 900 MHz band limits and were using SG_923 anyway. With the country now named in the official docs, Meshtastic is turning that workaround into a documented baseline.

The regional table shows why this kind of guidance matters. Nearby countries use different profiles, including MY_919, PH_915 and TH, so copying settings from across the border is an easy way to get off on the wrong foot. Indonesia’s spectrum rules have also evolved, from Permenkominfo No. 13 Tahun 2018 to later class-licensed spectrum regulations, and current official and secondary regulatory sources point to the 920-923 MHz band for LPWAN and IoT use cases. That lines up with Meshtastic’s SG_923 mapping.

Meshtastic’s own docs team treats this as part of the product, not a footnote. The documentation-maintenance page says documentation is an important ingredient of the project and is there to help users “hit the ground running.” For Indonesian users, that now means one less blind spot on first boot: set the region correctly, use SG_923, and start from a documented local default instead of a borrowed one.
