I am planning to use this Bluetooth chip as part of a larger project and the chip is connected to the SAM4S over SPI. As this is an addition to a major project, the project was not based in Atmel Studio. So this presents 2 major issues. I can not easily use ASF for easy development and another issue i can not find any documentation on SPI communication using this chip.

 

Things like which registers to write to, what values to send etc. I could port the BluSDK but it only has support for UART and not SPI according to this http://ww1.microchip.com/downloa... (page 22).

 

Is it possible to establish SPI communication with this chip at the moment?
