Bluetooth Heart Rate Monitor causing boot problems

Sorry for late response:

Just connected with the web ide and got this exception:

Uncaught Error: Function "setBTHRMPower" not found!
 at line 14 col 36 in bthrm.app.js
...ings.startWithHrm)){Bangle.setBTHRMPower(1,'bthrm');}
                              ^

Seems like the boot part of bthrm is not correctly loaded.
