Thank you koles for the pointer. I found the debug section where I can configure to use a service and set a register. However I’m running into a problem. I want it to send hex “0x2 0x30” but it’s instead sending hex “0x2 0x0 0x30”. I have the call setup like this:
Here are a few lines of the debug:
‘’’

I see in the documentation that it’s supposed to be 16 bit values, wouldn’t that be two hex digits? I realize I’m probably missing something obvious but not sure why I’m getting that 0x0 between my two sent values.
Thanks!
