Beginnner BLE Programming Guide for nrf52840 (ble-client)

[Justin Eddard]

Hello Everyone,

I have been using nrf52840 DK for several weeks. However I find it very difficult to understand the source code. I have experience only using arduino programming and it is quiet different with this board.

Could anyone recommend me any ble programming guide for this board?
What I need is simply read and write with ble using nrf52840. And this board act as a ble-client.

Thank You in advance.

Probably the "simplest" (sic) way is to use the Nordic UART Service (NUS): it gives you a transparent "pipe" through which you can just pass any arbitrary data, much like you do with a UART - hence the name:
