Got this Edge 1030 second hand just couple weeks ago, this HR strap was included (looks like never been used).
I had my old ANT+ speed/cadence sensors and connected without issues, also the Varia UT800 is working as well.
For Zwift only I had to order a new speed/cadence BLE set (for tablet use), got the kit today. Removed the old sensors paired the new sensors straight forward, tried to pair the HR strap and the EDGE 1030 just rolling the search.
What or how to troubleshoot the HR strap? I checked the battery is OK and overall looks like new. Cannot call back to seller the deal was weeks ago and don't want to bother them with this.
I can't justify a new strap purchase without proving myself this strap cannot work.
