With this code the Nexus will send messages that will be accepted by the LoRaWAN network. Also the Nexus board will listen in receiveslot to if the gateway is sending back a message.
Transmit
- Channel 0: 868.100 MHz
- Datarate 5 = Spreading factor 7, 125 kHz BW
- Full power
Receive
- Channel: 869.525 MHz
- Datarate 3: Spreading factor 9, 125 kHz BW
The timing for the receive slot is handeld in LoRaMAC_V10.cpp
This code will not:
- Change channels
- Change datarates
- Send MAC commands
The Nexus board is fitted with an ATMEGA328P and a RFM95 module.To adapt this code to other hardware change the LoRaWAN_V30.h. From the DIO's only 0,1 and 5 are used
- Arduino Pro Mini (3.3V / 8MHz)
- Hope RFM95
- PCB (ask Corbo or alternatively order it here)
- FTDI232 – jumper op 3.3V
- Male headers (30 pins)
- Femal headers (44 pins)
- Male jumper wire as an antenna
- (optional) BMP280 temperature sensor
