Telemetry on STM32F103C8T6 ...

[Atamanul]

Hello. I tried from IBusBM-1.1.5, the Ibus_sensor example. I tried it on the Arduino mega 2560 = Ok, transmits sensor data. I tried on ESP 32 = Ok, transmits sensor data. I tried on STM32F103C8T6 - Blue Pill = does not transmit sensor data. Please, can someone explain what can be done to make it ok!
