Fantastic.

I know this is an old post , but I recently come across this and it is exactly what I need.

Two things I need to know.

What would the best and smallest battery to use in this setup, and how long would it last?

I am interested in using a NODEMCU with a NRF24L01+ to read the beacon and send the data via MQTT to my broker. Would this be possible? and where would I start with such a project if it doesn't already exist?

So, the nRF24L01+ is acting as "controller" and Arduino (or any MCU) as "host" ... INTERESTING... and nice find [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-3fe7ec52-b8d8-4722-a602-1de2a9b1bb91/1447.contentimage_5F00_3.png:16:16]

Wow great post.

I have a question that is related but on slightly different topic (If you have not looked at this hoping others may read my comment and have an answer).

If these nRF24L01+ wireless modules can be made to transmit beacon advertising data packets would it not be possible to try and use a nRF24L01+ as an observer to sniff out advertising data packets from other BLE beacons. If so looking for pointers on how to do this if it is possible. I see you used a Bluetooth dongle for this purpose.

Nice update.

I am curious as to the range of your tags?
