Debugging Ebyte Lora that is using UART and STM Bluepill

[Mshar.2]

Hello programmers and developers,

I'm trying to communicate between two STM32F103C6T6A (Blue pill) and Ebyte Lora using UART. My program was working well on breadboard. But after soldering it stopped working.

Using USB to TTL converter i can see on my laptop that message is coming to Rx/Tx pins of Lora module. How do i check if it is being transmitted via antenna or not?

I've never tried debugging RF signals so any help is appreciated.

You'd perhaps use a HackRF One or similar SDR to visualize data transmission.

There are RF power meter type devices.

Best to have a matching receiving device (frequency, parameters, settings, etc) that can report or show packets pulled out of the air.
