    New project with Dirk: the open-source BLE Sniffer called Raccoon for Nordic's nRF5x line. Captures unencrypted connections incl. LE Data Length Extensions. Use 3 sniffers to track all advertisement channels. Encryption, 2M and Codec PHY will come soon!

    The new PTS Test Dongles support 2 BLE Peripheral Roles - while a bit expensive for a USB Bluetooth dongle, it's the first I've seen that supports more than one BLE Role. LE Data Length Extension would have been nice as well...
