Start hacking Bluetooth Low Energy today! (part 2) 

The report demonstrates budget-friendly BLE hacking techniques: using a Sonoff Zigbee 3.0 dongle (flashed with Sniffle) to sniff unencrypted BLE traffic in Wireshark and a Nordic nRF52 dongle with nRF Connect and the blatann library to discover GATT services and send characteristic writes to control a low-cost key-finder (e.g., toggling its alert). It covers setup steps, traffic filtering to identify write commands, and scripting interactions, positioning this workflow as a reliable learning and testing approach for BLE devices that do not use pairing/bonding.
