SPI connection to CrazyRadio

[nrn32]

Hi,

Can the CrazyRadio be connected to a micro controller via SPI and communicate with CrazyFlie?
In the sense can the radio break out used in this project (https://bitbucket.org/tbitson/crazyflie ... controller) be replaced with CrazyRadio with header connected?

Yes it is possible but not without some work (could be a lot of fun though ). The Crazyradio uses the nRF24LU+ chip which has an integrated MCU which the nRF24L01+ doesn't have, so this must be programmed to take commands from SPI or UART.

So, that would require reflashing the radio firmware ?

Yes, you would need to modify CR firmware to read in a command and then have it transfer the command to the transceiver.
