As the titles says, during my dive my transmitter will randomly stop transmitting. Previously, it worked great and never stoped updating pressure. Now it will show "---" for my pressure, then later I will hear the T1 "buzz" and will see my pressure, then will it will stop randomly. All firmware are up to date to the latest, battery is fairly new and shows "good" on my mk2i. At the surface via Ant it works fine.
