How to disconnect nRF8001 from a nRF52 board?

Hi Filippo,

I am also working on a project in which my Bluefruit NRF52 Board receives data from a few sensors like accelerometer, humidity, co2 level etc. and then should send this data in an float array to NRF8001 hooked up Arduino Nano. But I am really new to this BLE_UART concept, so can you help me with this communication? Have you succeeded with your project above? If so, can you share the codes?

You need a programmer. You can use one of our nRF5 development kit as the programmer for your board.

Anyway, for the development of your project, I would strongly suggest you to continue on our nRF5 Development Kit ($39) instead of the BLEfruit board.

It's could be easier to start and more straight forward with Arduino, but if you want all the features and more flexibility, I would suggest you to get started with our development kit and the SDK.

Founded that my nRF52 Bluefruit feather board has the S132 v2.0.1. Since I am new to all these stuff, could you explain me (or link to any references) how to flash the board firmware with your SDK, please?

I'm not sure which version the S132 you have with BLEFruit.

If you have the programmer to flash firmware on the board, I would suggest with our SDK as you pointed to. The SDK can be download here and the documentation is here.

First of all, I would like to thank you for the reply @Hung. Accordingly to this learn.adafruit.com/.../memory-map reference page, it seems that my Bluefruit nRF52 Feather come with the S132 Soft Device pre-installed. So this should be not a problem and I would be capable to handle both the BLE links to the Flora boards.

About the programming platform, I am started from some rough examples included into the "Adafruit BLE libraries for Bluefruit52" for the Arduino IDE and also available into the Adafruit_nRF52_Arduino github repo (github.com/.../Adafruit_nRF52_Arduino).

Is your SDK this (www.nordicsemi.com/.../nRF5-SDK) one?

Huge thanks again for your help, very appreciated!

@Filippo: The nRF52 is capable of having 20 connections at the same time. If you use latest softdevice.

I don't know which programming platform you are using for the Feather board. If you use our SDK , it is fairly easy to handle both Flora boards or to disconnect a board if you want.
