Cannot capture ATT protocol with BLE sniffer Moderators: adafruit_support_bill, adafruit

I am working with Adafruit BLE sniffer and wireshark. The only communication that I can see is the one happening on the link layer. I cannot see any upper level communication, for example ATT protocol. Could you give me an idea of what could be the problem.

I have this same question. I recently purchased a BLE Sniffer V2. I have it working in Wireshark. I see a stream of Advertisement packets. I select the device I am interested in in the nRF Sniffer toolbar. Then I pair the device to my phone. At that point I see a CONNECT_REQ. It seems like I should then start to see Empty PDU packets but I don't. I change settings using the phone app and I see no relevant packets in Wireshark.

Is there possibly a limitation of the sniffer that I am hitting? I don't know what bluetooth version my device is using. Is it possible that BLE 5 packets are incompatible with the sniffer out of the box?
