hey, I am trying to build a wireless telemetry using nrf24 and arduino for pixhawk, due to high price of sik radios and disadvantages of other ways to add telemetry like using esp8266 and bluetooth telemetry, nrf24 is a great and cheap way to make long range telemetry. please help me from scratch.
Good places to start are:
Robin2's simple rf24 tutorial.
The Last Minute Engineers rf24 page.
Be aware that the packet size limit for the rf24 radios is 32 bytes.
The biggest mistake that new users of the rf24 radios is lack of sufficient current on the 3.3V power supply. I use homemade adapters like these.
