BLEClientCts

BLEClientCts is a helper class that implements adopted Current Time Service (https://adafru.it/BiT) , which enables you

to receive time from devices such as an iPhone or iPad.

API

Client CTS OLED Example

The client_cts_oled (https://adafru.it/BiU) example uses the Adafruit FeatherWing OLED (https://adafru.it/sao) to

display received time.

Sketch Requirements

In order to use this example sketch the following libraries must be installed on your system:

The Bluefruit nRF52 Feather codebase is in an early BETA stage and is undergoing active development

based on customer feedback and testing. As such, the class documentation here is incomplete, and you

should consult the Github repo for the latest code and API developments: https://goo.gl/LdEx62
