For indoor activities where I have GPS disabled, HRM Pro Plus is not reporting data to Data Fields, specifically Distance and Pace. This is the case for all indoor type of activities, where GPS is disabled. I can go outside and launch a Run activity (w/GPS enabled) and HRM Pro Plus reports perfectly. I've added data fields Distance and Pace to the HITT activity but cannot get any data from HRM Pro Plus. I have confirmed it is connected via ANT+. Any ideas?
