Locha Mesh

The Locha Mesh is a radio network for off-grid messaging, Bitcoin and other cryptocurrencies transactions without access to the Internet. We are developing the protocol and the firmware for affordable devices like the Turpial, Harpia, or their DIY equivalents. We adhere to open source ethos at every step and aim to make this tool as decentralized as possible so users can transmit with freedom.

Getting started

The Locha Mesh is under active development. If you are a C/C++ developer and you want to join the development efforts, or you are a maker and would like to setup the development kits to have them ready for when the firmwares are ready, or if you are a phreaker and you want to hack new ways for decentralized communications, please follow the instructions below on how to get started.

• You need to acquire a Turpial device (currently only available as a pre-order); or compatible development hardware which is comprised of an ESP32 and a radio module.

• Once you have the hardware you need to follow the instructions on how to flash the ESP32, and how to flash the radio module.

• If you need help, please join our Telegram group here.
