# CubeCellRepeater
|
||
|
||
This is the code for a simple repeater node for the meshtastic project: https://github.com/meshtastic
|
||
|
||
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. Depends on the NanoPB Lib and Base64 Lib (see platformio.ini). Serial output speed is 115200.
|
||
See the provided platformio.ini for built-in environments. Default is cubecell_board.
|
||
|
||
Will repeat packets ONCE. To prevent flooding the last repeated packet ID will not be repeated again.
|
||
|
||
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.
|
||
You can use this for range tests.
|
||
|
||
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 14 bytes.
|
||
|
||
The Repeater is not working for “medium range” setting due to the tight timings. It’s best for "very long range" and "long range", but is working for "short range", too.
|
||
|
||
"#define SILENT" to stop serial output.
|
||
|
||
"#define NOBLINK" to NOT getting a red blink from the RGB LED for the duration of sending a packet (can be quite long at speed setting 3).
|
||
|
||
"define NO_OLED" to turn off messages on the OLED. Supported Boards for OLED mode are HTCC-AB02 and HTCC-AB02S (cubecell_board_Plus and cubecell_gps).
|
||
|
||
Modifying radio settings for your own channels:
|
||
|
||
Edit the CONFIGURATION block in config.h
|
||
|
||
e.g.
|
||
#define REGION RegionCode_EU865 - defines your region (to EU865). For US, use RegionCode_US, for CN use RegionCode_CN etc. See config.h for more supported regions.
|
||
|
||
TX_MAX_POWER 14 - sets output power to 14 dB. This value will also be used, wenn output power is set to Zero in your RegionCode (0 = max. power). TX_MAX_POWER will be ignored, when higher than RegionCode maximum
|
||
|
||
char MeshtasticLink[] = "https://www.meshtastic.org/c/#GAMiENTxuzogKQdZ8Lz_q89Oab8qB0RlZmF1bHQ=" ; (Example String for Channel "Default")
|
||
Put your own Mesh Link into the "" . The Code will compute the channel settings based on that information.
