Reverse Engineering a Quadcopter RC, or: How to not miss the needle while throwing the haystack in the air (Part 4)

Part three of this series covered tagging into the SPI communication between an Arduino Uno and a nRF24L01+, followed by the transceiver inside the quadcopter RC. We have seen registers being read from and written to for initializing the transceivers … Continue reading

Reverse Engineering a Quadcopter RC, or: How to not miss the needle while throwing the haystack in the air (Part 3)

In part two of this series, we first tried to interpret the data received in promiscuous mode from the quadcopter RC radio. We then started collecting data from the SPI interface of an Arduino Uno controlling a nRF24L01+ transceiver. In … Continue reading

Reverse Engineering a Quadcopter RC, or: How to not miss the needle while throwing the haystack in the air (Part 2)

Part one of this series covered the first three steps towards reverse engineering a quadcopter RC. The steps were “check the documentation“, “listen to the radio” to get the right channel and “listen to that channel intensively” in promiscuous mode. … Continue reading
