Re:Make a low-cost Bluetooth LE packet sniffer with Wireshark

Bluetooth is a frequency hopping protocol. Most hardware is provisioned to access one channel at a time. In BLE, even the initial setup can happen over once of three channels. My understanding is that it's difficult for a sniffer to work reliably (including the one in the OP) unless the hardware is provisioned to receive multiple channels. But I'm not an expert in it.

You're probably right, you just reminded me of btlejack, a project for BLE sniffing which can use 3 distinct listeners to reliably sniff setup:
