XERT EBC APP shows wrong HR-Strap values

The XERT Service connects with my viiiva via Bluetooth and just shows bullshit values such as 23,32… etc. On Strava mobile via bluetooth it shows correct values (66, 67…)
Via ANT+ on Zwift, it shows correct values as well…

Why do I need it? in order to control my trainer via the app and track the HR there as well (thats important for the smart workout feature, right?) and to simulate the workout on ZWIFT as well.
Idea was to connect the app via Bluetooth and Zwift via ANT+…
My Hr can send bluetooth and ant+ at the same time…

Whats the issue with the XERT EBC app?

seems like the strap works everywhere with bluetooth (zwift, 4iiii app, strava app) but just the XERT app shows wrong values after connecting. Sometimes it shows a right value for some seconds, and then it jumps back to low values such as 28…

Send a note into support@xertonline.com and let us know which HR strap you’re using.
