RF24BLE is the library that makes an nrf24L01+ chip (1$) into a BLE advertising beacon and can be used for LOW payload advertising like sensor data etc.

• This library works on top of the RF24 library by TMRh20 (https://github.com/TMRh20/RF24)
• Tested using Arduino v1.8.5(windows) and Arduino v1.0.5 (ubuntu)
• Tested with "nRF Connect for Mobile" app on google play store on android LINK: https://play.google.com/store/apps/details?id=no.nordicsemi.android.mcp&hl=en
• Tested on Iphone using iphone5S and LightBlue BLE app LINK: https://itunes.apple.com/in/app/lightblue-explorer-bluetooth/id557428110

• Connect the nrf24L01+ to the SPI pins of your specific arduino. Choose and change the Chip enable (CE) and Chip select (CS) in the code corresponding to your connections

• clone the repo and paste the RF24BLE folder in the folder "libraries" in the sketchbook area. e.g "Arduino/libraries/RF24BLE"

• open the arduino ide and choose an example from the file->examples menu and upload any example

• Download and install the app "nRF Connect for Mobile" app from the google play store on an android device.

• open the app and click on scan and the advertised packet should be shown in the list in the app
