# 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:
|
|
|
|
Will repeat packets ONCE. To prevent flooding a short list of received packet IDs is checked against the ID of the current packet.
|
|
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 any packet meeting the radio settings, but the serial output is based on the assumption that the node receives meshtastic packets.
|
|
"#define SILENT" to stop serial output.
|
|
|
|
Modify radio settings for your own channels:
|
|
|
|
Look for the following defines and change to your needs. The settings will be stored in "CanSet" and used to configure the radio.
|
|
|
|
#define LORA_SPREADING_FACTOR 12 // [SF5..SF12]
|
|
|
|
#define LORA_CODINGRATE 4 // [1: 4/5, 2: 4/6, 3: 4/7, 4: 4/8]
|
|
|
|
#define LORA_CHAN_NUM 0 // Channel Number (meshtastic specific)
|
|
|
|
|
|
Note: with "HW_VERSION" you select your country/continent settings. For US use HW_VERSION_US, for CN use HW_VERSION_CN. See Meshradio.h
|
|
|
|
#define HW_VERSION_EU865 // define your region _before_ including MeshRadio.h !
|
|
|
|
#include "MeshRadio.h"
|
|

ChannelSettings ChanSet={ TX_OUTPUT_POWER, ChannelSettings_ModemConfig_Bw125Cr48Sf4096, mPSK, "Default",
|
|
LORA_BANDWIDTH, LORA_SPREADING_FACTOR, LORA_CODINGRATE, LORA_CHAN_NUM };
