It seems to be blue peak range is the dwell time?
Yes, PPK2 can be used to measure transmission times quite accurately. Also, with SDR, I can observe the frequency, bandwidth, and modulation.
I am experimenting with Wio E5 mini for long distance communication. At first I wrote the code with AT commands. But now I found that I can write it on Arduino using radiolib library, so I don’t use STM32Cube.
Still debugging, but for your information.
