Hi, just got an Edge 25 and the "Bike speed sensor and cadence sensor" kit.
got it all installed and the edge detects both devices all ok.
reading the installation instructions it says that once installed you should spin the wheel and the speed sensor will flash the green light 5 times to confirm it is working ok.
however, when i took the sensor out my pocket to start to fit it, it was already flashing and stopped shortly after.
now when i spin the wheel nothing flashes, as i assume the sensor thinks it's already set up?
do i need to reset this and make it flash whilst on the wheel?
also, will it auto detect the size of the wheel? as the edge 25 has no settings for wheel size etc.
the cadence sensor was fine, as that didn't start flashing until i installed it on the crank and span it a couple of times.
