-The ConnectIQ / Firmware RE community: Atredis Partners reverse engineered the Garmin Forerunner 235 firmware and virtual machine completely, publishing a detailed blog post about it. The researcher noted that Garmin was easy to work with while reporting issues — explicitly saying this wasn't an indictment of their products. Garmin did not sue them. They cooperated on vulnerability disclosure. 
  
-The GarminBLE project: A Wireshark plugin for Garmin's BLE protocol has been publicly available on GitHub for years with no legal action.+== The ConnectIQ / Firmware RE community ==
