if you want to use WisNode-LoRa to connect Arduino UNO, you need to wire this way:
If you use our Arduino reference example, you need to use two serial pins, one as a serial port for sending AT commands and one as a debug output port.
At this point you need to wire this way:
After the program download finishes running, you should see this message on the debug serial port:
The Arduino sample program is just for reference. It implements OTAA network access or ABP network access and wants the gateway to send a packet of data. If you need to implement other functions, you need to develop it yourself.
