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.

Wow, I have one of this!!! Thanks for sharing.
Nice Tinti! Let me know if you got it working! đ
Is it possible to send data from smartphone to nrf24l01+ using BLE?
Hi, this is really interesting. Is it possible to send data from smartphone to nrf24l01+ using BLE?
AFAIK is it no possible. It only supports sending advertise message.
Hi Tq Very much for the response, i have seen one link
in that he is controlling LED using Smart Phone Using BLE
Hi saiteja, thank for this video. So this guy discovered a new way to get the smartphone communicating with the nRF24. I wasn’t aware of it. Thank you very much!
