Concept2 Forum

I am after some advice please regarding chest strap please. I have used Garmin chest strap for the last 2-3 years and have had no problem connecting. For some reason the strap will now not connect to the PM5. I have completed all the troubleshooting checks (wires / battery etc.) and updated firmware. Initially I thought the strap was not working and even invested in new strap. I remain baffled as to why the strap will not connect. I would appreciate any advice on this issue. Thank you.

I assume you've tried what's below, but just to be sure we're on the same page:

What happens when on the PM5 you click Connect and then Connect Heart Monitor? Does is search for ten seconds and show nothing? It should show both ANT+ and Bluetooth options, so you need to select one and then hit Confirm. Then tell Ergdata (if you're using it) to "remember this HRM."

If that's what you've tried, I think that the most likely suspect is a fault with the PM5. There's a slim chance that your HRM is connecting to some other device instead, but that would affect Bluetooth and not ANT+.

Also, you might try updating the PM5 firmware. You can do this with Ergdata (assuming it can connect) or with a printer cable and a Windows computer and Concept2 Utility (free download).

Thanks for the response. Yes - have tried all you mentioned. I updated the latest version of firmware yesterday so do not think that is the issue. I will double check all troubleshooting advice and see how it goes. Frustrating as I have not had this issue before. even more baffling is that the Garmin watch wrist HR does connect to the PM5 without a problem but the wrist HR is erratic and not accurate.I will keep perservering with the issue. Thanks once again.

Factory reset of PM5 seems to have done the trick! New HR chest strap now picked up and connected - will give it a 'run out' tomorrow on work out.
