Arduino + NRF51822

[Hani Abidi]

Hello,

I am really confused at the moment if the Arduino SDK is for NRF8001 or does it also works for NRF51822? Can you please help me in getting started?

Thanks Hani Abidi

Hi Hani Abidi

Thank you for your interest in our products. Welcome to Nordic.

I think when we talk about the Arduino SDK we are talking about the nRF8001, i.e. to use it with Arduino board. There is also a nRF8001 getting started guide here.

The nRF8001 is a BLE connectivity chip, i.e. it needs an external MCU in order to operate. The Arduino SDK is to use the nRF8001 where the Arduino would be the external MCU. On the contrary, nRF51822 is a System on Chip, i.e. it has internal MCU to carry out operations, and therefore does not need an external MCU. You can however use the nRF51822 as a connectivity chip with Arduino if desired.

I think the most simple way of getting BLE connectivity is to use the nRF8001 together with Arduino board and the nRF8001 Arduino SDK. However, if you wish to use nRF51822, then there are getting starded guides here: (1) (2)
