Hello, I have the RAK811 915Mhz node and I want it to connect it with my Arduino Uno,
I have followed the tutorial given by RAK: https://downloads.rakwireless.com/en/LoRa/RAK811/Application_Notes/Get_Start_with_RAK811_WisNode-LoRa.pdf
And I didn´t have any problem related to upgrade the firmware, also, I connect the node with TTN via OTAA with RAK_SERIAL_PORT_TOOL_V1.2.1, I receive messages in TTN with the AT command, for example “at+send=lora:2:12345678”, all is OK.
Now I want it to connect it with my Arduino Uno, because I want to use it to make some measurements and send data it to TTN, I used this Arduino library: https://github.com/RAKWireless/RAK811/tree/master/Arduino%20Library
I used the Join Network OTAA example,
But doesn´t make connection with my gateway, it never sends any payload to TTN, also, I followed other tutorial: https://www.hackster.io/naresh-krish/using-the-rak811-lora-module-with-arduino-a38de8
but same results, not working, it doesn´t send information to TTN.
By the way, which is the correct way to connect it with the arduino is the correct way to connect it with the arduino, TX an RX of each other via cables or just connecting the RAK811 into the Arduino?
With the RAK serial port tool I don´t have problems sending information to TTN via AT commands, maybe I´m not using the correct arduino library, I don´t really know.
Thanks in advance and greetings!
