Datasheet

Once the sketch is running on the nRF52 Feather you can proceed with the one-time pairing process, described below.

Pairing to your Mobile Device

Before you can start receiving notifications, you will need to 'pair' the nRF52 Feather and the mobile device.

The pairing process causes a set of keys to be exchanged and stored on the two devices so that each side knows it is

talking to the same device it originally bonded with, and preventing any devices in the middle from eavesdropping on

potentially sensitive data.

The one-time pairing process is described below, and assumes you are already running the ancs_oled sketch on your

nRF52 device.

1. In the Settings app go to Bluetooth:

Make sure that the Adafruit_SSD1306.h file has the 'SSD1306_128_32' macro enabled. Running the sketch

with 'SSD1306_128_64' set will cause corrupted data to appear on the OLED display.
