====

Arduino library for basic Bluetooth Low Energy support using the nRF24L01+

(basic support = sending & receiving on the advertising broadcast channel)

You will also need to install the RF24 library installable either from the Arduino IDE or https://github.com/TMRh20/RF24 .

Note: the BTLE class and the examples are licensed under GPLv3. However, the

helper functions in btle.inc are (C) 2012 by Dmitry Grinberg under a separate

license (see file for details).

FAQ

===

The nRF24L01+ can only send and receive up to 32 bytes. For advertising messages, this means 32 - 6 (MAC) - 2 (header) - 3 (CRC) =  21 bytes of payload can be sent and received at most. Consequently, a full iBeacon message won't fit in there and will never be received. Also, if you're sending advertisements from your phone, the device name alone will take up a significant chunk of that budget.
