Hello Will , Oh sorry! The controller I am going to use is http://ww1.microchip.com/downloads/en/DeviceDoc/Atmel-2549-8-bit-AVR-Microcontroller-ATmega640-1280-1281-2560-2561_datasheet.pdf Planning for implementing the Mynewt OS and the BLE stack on this controller with SPI,HCI. We planned for interfacing BLE with SPI , so wanted information regarding this type of implementation.
