/****************************************************************************
|
|
* This example was developed by the Hackerspace San Salvador to demonstrate
|
|
* the simultaneous use of the NeoPixel library and the Bluetooth SoftDevice.
|
|
* To compile this example you'll need to add support for the NRF52 based
|
|
* following the instructions at:
|
|
* https://github.com/sandeepmistry/arduino-nRF5
|
|
* Or adding the following URL to the board manager URLs on Arduino preferences:
|
|
* https://sandeepmistry.github.io/arduino-nRF5/package_nRF5_boards_index.json
|
|
* Then you can install the BLEPeripheral library avaiable at:
|
|
* https://github.com/sandeepmistry/arduino-BLEPeripheral
|
|
* To test it, compile this example and use the UART module from the nRF
|
|
* Toolbox App for Android. Edit the interface and send the characters
|
|
* 'a' to 'i' to switch the animation.
|
|
* There is a delay because this example blocks the thread of execution but
|
|
* the change will be shown after the current animation ends. (This might
|
|
* take a couple of seconds)
|
|
* For more info write us at: info _at- teubi.co
