Hi, I am a student and new to LoRa and electric things, currently building a lora end device.
I want to connect a rak3272s breakout board to an arduino uno board to send some sensor informations to the TTN/TTS, but as I see on the internet, people have to program the chips/breakout board instead of using it as a module. Planning to use UART instead of SPI. And I am not quite understand the information from the document.
Therefore, I would like to ask:
- Could I directly connect the rak3272s breakout board to the arduino uno board to use it as a module? But not a standalone device?
- If I could, could I directly send AT command with the arduino board? Or I must setup/config the breakout board before hand with a ST-Link USB Dongle (like RAKDAP1) a must? For example, could I config the breakout board with Arduino IDE while it is connected to the Arduino board then do my development/config, without using tools like RAK Serial Port Tool?
- Connecting just the power, ground and UART2 rt/tx from the rak3272s to the arduino would work?
Thank you!
