NRF51 DK ADC sampling

[Manu]

I want to use NRF51 DK to sample 2 analog signal continuously (300Hz) and send it to a smartphone using BLE. I need advice on

• Which nrf example to use to code my DK?
• Which android app to use for communication?

I want to graph both the analog signals separately in the app as well.

Hi Manu

This thread points to that we have available on the nRF51 side. For the app, you can use nRF Toolbox app which is available for Android. In the app there is UART subapp which receives and displays results from the Nordic UART Service (NUS). You can also use nRF Master Control Panel for Android to receive raw messages from nRF51. Available on Google Play. I think there should also be a specific nRF UART app available which is perhaps more simple implementation than the nRF Toolbox app. Source code for the nRF UART app and the nRF Toolbox app is available on Github.
