Sending Bluetooth Low Energy data from Nordic nRF24L01+

What a great hack this one from Dmitry Grinberg!

It is amazing to know you can use these cheap nRF24L01+ dongles to communicate (unidirectional unfortunately) with a Bluetooth 4.0 Low Energy (BTLE) devices (your smartphone for example).

In fact the nRF24L01+ doesn’t connect to you BTLE device, but sends data using the “unsolicited advertisements” channels. Not a big problem if all you need is a network of sensors because sensors just need to send data anyway.
