Hi all.
I have purchased some Reyax RYLR998 LoRa modules and would like to send AT commands to them using my UNO.
The RYLR998 is a 3.3V device.
I've bridged GND and RESET on the UNO, powered the module off the 3.3V and fed the TX to TX and RX to RX through two voltage divider circuits.
I opened the serial monitor, set the baud rate to 115200 and tried to send the command "AT" but get no response.
I don't see my message or a response come up.
Am I totally barking up the wrong tree here? Perhaps I need to connect the TX, RX pins with a Mosfet instead of through a voltage divider circuit? Maybe the RX pin will not need a voltage divider circuit at all?
Thanks for your time.
