When the airspeed is set to 250kbps, the radio station cannot work normally

I found a problem. The radio station was made by myself. When I set the airspeed to 250 kbps, the station could not connect and the green light started flashing. Do you also have this problem?

No source files, tests, hardware details, or entry points are named. Start by reproducing the connection failure with the radio airspeed set to 250 kbps and inspect the SiK firmware and tools involved in radio configuration. Done means the station connects normally and the green status light no longer flashes at that setting.
