RAK811 and RAK4200

Can I control RAK811 and RAK4200 with the same AT command?
I am trying to change rak811 to rak4200.

Thanks.

The 811 uses a different MCU than the 4200, and modifications may not be possibleļ¼

Which one should I use for our new design? I mean which one is better?
And does rak811 have unique device eui?

What is the way you use it?

I plan to use RAK LoRa module for the air monitoring system. We are using UART to control the rak811 module.

If you use less pins and only use the LORA feature, RAK4200 is recommended as it meets your needs and is cheap.
