I have been struggling with getting the sensors paired all this time and just about gave up! Removed batteries, went for a ride, etc etc downloaded the update firmware three times in case that was the issue. But then suddenly today, started the whole process all over again and still no luck until!!! – I started pairing the rear sensor but had forgotten to put it on the tyre and as I was screwing it in while the pairing process was ongoing and BINGO hahaha it connected, so I quickly did exactly the same with the front tyre and it worked like a charm! I’m sooo happy 😀
