goTenna Mesh (GTM) is a miniature UHF radio transceiver with ad-hoc mesh networking capabilities, providing a peer-to-peer text messaging service similar to two-way paging, but without any central infrastructure. The GTM device itself has a headless design and is intended to be operated from a mobile phone, tablet or computer connected via Bluetooth LE. No Internet or cellular connection are required.

The manufacturer publishes a simple app for iOS and Android. Until recently, a binary-only SDK was also available for app development, however it has been officially discontinued in November 2022. Some third-party applications based on the SDK are available.

The hardware, firmware, protocols, endpoint app and SDK are all proprietary closed-source and most technical documentation is NDA-walled.

The pyGT project attempts to collect, organize and develop open-source information, code and resources with the goal of enabling fully transparent open-source development on the goTenna platform without relying on any restricted, or restrictable components.

The gtm-lab playground was launched in 2021 to develop an alternative, open-source implementation of the goTenna Mesh radio protocols on generic ESP32 + RFM9x hardware.

2019-02-02 The goTenna Mesh serial console feature has been quietly removed from Mesh firmware version 1.1.12. Users requiring this feature are advised to use version 1.1.8. Read more.
