From out of the blue, Bluetooth stopped working. No update and no apps added prior to it stopping. Here is a breakdown

• firmware is 2.12
  
• Bluetooth is just a grey symbol
  
• reboot shows the ->Bluetooth at the bottom
  
• tried load no apps, no connection available
  
• try to connect from gadget bridge. Also tried to connect with web site, no connection available
  
• I factory reset the watch, no connection available.
  
• restarted my phone, no connection available
