Query Supported Frequency of RAK2247

Is there a way to programatically query RAK2247 USB device whether it is 915MHz or 433MHz or another variant?

Linux machine with HMC/miniPCIe with USB slot

I don’t believe there is any way to do that, at least not between 868 and 915.

The 433 MHz builds would have different RF front end chips, which might have slight behavior differences if you got very deep into the code.

The main indication is that a resistor having no electrical role is placed in the little chart on the bottom at the same time as the front end chips and support components that actually determine the frequency are placed.
