BLEClientUart

BLEClientUart is a wrapper class for the client side of the NUS or 'Nordic UART Service' (aka 'BLE UART'). It is only

required when your Bluefruit nRF52 board is acting as Central communicating to other BLE peripherals that expose

the BLEUart (https://adafru.it/yud) service.

API

BLEClientUart has the following public API:

Examples

The following example shows how to use the BLEClientUart helper class.

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

// Callback Signatures
