Vector 3 calibration to wahoo bolt

Each time a try to calibrate I invariably have to retry 2,3,4 or more times before I’m successful. Sometimes I just give up and if I do the power readings still appear to be correct, thankfully.

I’ve followed all the instructions, etc but find this issue very frustrating as I don’t know if the pedals are faulty, despite the fact that they feedback data throughout the ride regardless of them being calibrated or not. 

Does anyone else suffer with the same problem or just me? 

Any advice would be helpful, thanks.

    I had that issue with the Roam and it would hang until a power cycle.  I sent it back to Wahoo.  Wahoo claimed it was the Vector.  I didn't dispute that, I just told them they need to have better error handling, so that the Roam would not hang, and allow for a second attempt at calibration.

    It is unlikely it is the Vectors unless Wahoo are not handling the returned torque value correctly. The message is a standard ANT+ message.

    I'm assuming that you were paired to the pedals over ANT, were you paired of BLE?

    Paired over ANT+.  Wahoo claims it is a standard ANT+ msg, which I have no doubt it is, but I had the same symptoms on two different Vector 3 sets. Something is wrong someplace.

    Unfortunately I don't think Wahoo supports logging of the ANT traffic.

    I can tell you that looking at the ANT traffic that the Edge gets from the pedals the message is correctly formed.

    I've also used the SimulANT to view the data sent from the pedals and it conforms to the spec.

    I'm not sure where this leaves you if Wahoo are not prepared to log the message it is receiving and show that the message is at fault.

    One thing that might be going on is that the Wahoo unit is not waiting long enough for the Vector pedals to complete the calibration process. Because there is additional pedal to pedal communication going on during the calibration process the time to complete it can take longer than calibrating a single sided system.

    I don't know how long Wahoo waits for the process to complete before they decided that it has failed. They may need to increase their timeout period.

    You could ask them how long the unit gives a power meter to complete the calibration process and whether they could increase that time.

    I think this would explain why it works sometimes and not other times.
