How to retrieve advertising payload from iBeacon / BLE

Question

How do you retrieve the advertising payload for a Bluetooth LE emitter in linux?

Specifically, I\'ve configured arduino\'s and R-PI\'s using hcitool to act as iBeaco

Answer 1

Since libpcap-1.0+ now supports Bluetooth capture you can use Wireshark/tshark/tcpdump to capture and display Bluetooth packets - both BTLE and other packet types.

To capture the LE packets with Wireshark you will still need to tell the Bluetooth interface to query for LE packets, as mentioned in the previous answer:

sudo hcitool lescan --duplicates &

In addition if you want the adapter to do a periodic query for Bluetooth devices, which are in discoverable mode, you can run (though these queries won't pick up BTLE emissions):

sudo hcitool spinq
