CubeCellRepeater
This is the code for a simple repeater node for the meshtastic project: https://github.com/meshtastic (https://www.meshtastic.org) The Meshtastic project is in no way affiliated with or respnsible for the CubeCellRepeater project.
To be compatible with meshtastic project, portions of their code was used. (c) Copyright Meshtastic Project (and others).
Hardware: The actual node can be one of the LoRa CubeCell nodes by Heltec Automation: https://github.com/HelTecAutomation/ASR650x-Arduino/
Notes:
Intended for use with the platform.io IDE. Serial output speed is 115200. See the provided platformio.ini for built-in environments. Default is cubecell_board.
Will repeat packets ONCE with HopLimit reduced by one. To prevent flooding the last 64 repeated packets will not be repeated again. If the HopLimit was already 0, the packet will not be repeated.
Keep in mind that re-sending packets will cause the initial sender to assume that the packet is "received" or at least in the mesh. If no other meshtastic node is in range of either the node or the repeater, the message will still be shown as received.
Will work with most packets meeting the radio settings, but the serial output is based on the assumption that the node receives meshtastic packets. Minimum size for none-Meshtastic packets is 16 bytes.
"#define SILENT" in main.h to stop serial output.
The node can decode meshtastic packets meeting some requirements:
- they key is the default meshtastic key or provided by you (see main.h)
- the packets are sent over channel 0, primary channel. This should already be true for all telemetry, node info, traces and DM.
##Modifying radio settings: edit the main.h

For lora modem settings you should always try the default (LongFast), it's proven to be THE setting to go for. If you want to try other presets, here is the list:
