LoRa Shield Modulation Setting

Hi, I am wondering if I can change the modulation setting such as using FSK and GFSK while using the Cytron Lora Shield as this shield is based on RN2903 chip. I referred to the chip's datasheet (http://ww1.microchip.com/downloads/en/DeviceDoc/50002390E.pdf) and found that this chip support FSK and GFSK. If possible, can anyone guide me on how to change the modulation settings? Thank you for your time

You can actually check out the documents under Microchip website: http://www.microchip.com/wwwproducts/en/RN2903

Thanks! I was looking for at the wrong document all this time.

Im still having problems in changing the transmission mode from LoRa to FSK/GFSK even though I have referred to the command reference document (http://ww1.microchip.com/downloads/en/DeviceDoc/40001811A.pdf) but I dont know how to input those commands.

Hi,

It is using UART Interface. So just input exactly the command using UART.

If you are using Arduino, it is like

Serial.println("radio set mod fsk");

But I would suggest you try other commands before trying this, such as "sys get ver", "sys reset", etc to make sure you can communicate with the module. Check page 12 of the document for UART Interface settings.
