A companion node is the device you carry or keep at your desk to send and receive messages on the mesh. It connects to your phone or computer over Bluetooth or USB and runs MeshCore firmware. Companion nodes are not expected to relay traffic for others — that role belongs to Repeater Nodes.
Commercial Prebuilt
Off-the-shelf options require no soldering or assembly. You purchase the device ready to flash or already running MeshCore-compatible firmware. The following nodes are recommended by the HRMesh community.
