I’ve been having some trouble with a Wahoo Tickr that I just bought back in August, so I contacted Wahoo support this morning. I thought I was running latest, but that turned out not to be the case because they released a new firmware (1.14.0) a couple weeks ago that I missed. Updating is easy with the Wahoo Utility application, just put on the sensor (so it stays awake) and connect to it with the app on your phone. It should provide a button to upgrade the firmware. Hopefully this fixes the problem, because I’m useless without HR data…
Wahoo Tickr Firmware Update 1.14.0
