Set GPIO over Button click

Inspectron

I`m a newbie at Bluetooth Low Energy and Nordic Chips. I bought a DK for the nRF51822. I would like to set I/O pins over android and iOS application. 1.So what application is the best to start with? 2.Or is there already an app which light up a led or something with a button click? 3.What code I need to load on the nRF51822? 4.If I need to write my own Service, how should i do that in function with setting GPIO?

    Hi

    A good place to get started with nRF51 and BLE development is reading this blog

    Update 12.11.2014 The blog pointed to above contains reference to the ble_app_lbs example (led button example) which is perhaps the most simple BLE example existing for nRF51822:

    • Write to a characteristic on a central device and a led lids up on the nRF51822 development kit
    • When you press a button on the dev kit, characteristic value is changed on the central device.

    The following example is an add on to that functionality, where you have additional two characteristics, where the example has two leds and two buttons.

    • Press the second button and a value is passed to the central device that contains four bytes
    • Write to the second characteristic from a central device and a led is blinked on the dev kit

    Note: The example is implemented for nRF51 SDK v5.2.0 and softdevice S110 v6.0.0.

    To connect to the above example from a central side, you can use Master Control Panel for Windows, LightBlue app for IOS or Android (available on App Store and Google Play), or nRF Master Control Panel for Android. Below is also an Android Studio project for Android SDK 18, dedicated for the ble_app_lbs example
