Configuration!

Which board do you have?

There's a few products under the Bluefruit name:

If you are using the Bluefruit LE Shield then you have an

SPI-connected NRF51822 module. You can use this with

Atmega328 (Arduino UNO or compatible), ATmega32u4

(Arduino Leonardo, compatible) or ATSAMD21 (Arduino

Zero, compatible) and possibly others.

Your pinouts are Hardware SPI, CS = 8, IRQ = 7, RST = 4

Bluefruit Micro or Feather 32u4 Bluefruit

If you have a Bluefruit Micro or Feather 32u4 Bluefruit LE

then you have an ATmega32u4 chip with Hardware SPI,

CS = 8, IRQ = 7, RST = 4

Before you start uploading any of the example sketches, you'll need to CONFIGURE the Bluefruit interface -

there's a lot of options so pay close attention!
