Hi I'm working with rylr998 lora antenna and got some problems.
What I've first tried is connecting ryrl998 antenna and arduino uno board.
And through Serial moniter, if I type the AT, I could see the message +OK appears.
The next thing I've tried is connecting the rylr 998 antenna and arduino nano 33 iot board.
(This one is the main purpose. I have to send the data to cloud which received by lora antenna)
However, if I type the AT at the serial monitor, nothing happens.
I pinned all the wire correctly, same as uno
VDD -> 3.3v
GND -> GND
RX - > RX
TX -> TX
Is there anyway to make it work?
