KT1 21ac - Node Details

Previously known as !ef3607b6 KT1 07b6 (until 2026-01-24) — history from before the firmware 2.8 upgrade lives there.

No position received from this id. Firmware 2.8 switches position and telemetry broadcasts off on public channels when it is installed. To share location again, set the channel's position precision above 0 in the Meshtastic app (Channel → Position); telemetry has its own toggles under Module config.
