I am using the nRF51822 Development kit USB dongle to try to sniff a BLE connection between two other devices. I have installed Wireshark, flashed the firmware onto the dongle, and run the sniffer program as administrator. The nRF51822 dongle is placed between master and slave - less than 6 inches from the slave device, and about 1 foot from the master device.
My advertising device shows up as in the attached screenshot (sniffer.png). I hit 'w' to launch Wireshark. The advertisements show up as expected (wireshark.png). After connecting master to slave, however, no further packets are sent to wireshark, even when I explicitly send requests from master to slave and data back, etc.
I don't have any encryption set up between the two, and can't think of any other issues that would cause this. I've attached both the pcap file and the log file. Any suggestions are appreciated.
EDIT: forum would not let me upload pcap file, so it's attached as capture.pcap.txt. Rename it to capture.pcap to use it with Wireshark.
