I recently bought an Atomos Ninja with the Atomos Connect module and an UltraSync Blue to pair devices via Bluetooth.
I couldn't find an updated list of compatible devices, so I started one.
Timecode Systems, the original creator of the UltraSync One and Blue, was acquired by Atomos, which makes monitor recorders such as the Atomos Ninja or Shogun. The UltraSync Blue is also compatible with all other Timecode Systems devices.
