Simultaneous OHR and HR strap data in a datafield

Hi,

My first data field compared the OHR to an external strap connected via the ANT+ stack (ie not the sensor hub).

Reading through the API Documentation it doesn't seem possible to do the following:

1. Use the OHR and

2. Have an HR strap connected under accessories

3. Then get HR rate data from both simultaneously

My data field currently has to be visible in an activity to connect to a ANT+ strap (as not known in accessories ie external) then it will compare the OHR and write data to a FIT file. Users are having issues in that if they start an activity prior to the data field being made visible no ANT+ data is available.

Q1: Should I have my ANT initialisation code in onStart() rather than in the field initialise() method?

Q2: Is it possible to listen to both the OHR and a known connected HR strap using the built in sensor API?

Regards,

David

To use an external strap along with OHR, the external HR strap can not be paired under sensors and accessories, and the communications in your DF to the external sensor must be done with ANT or BLE. You can't use Sensor to get data from OHR and the strap at the same time.
