Dear developers, thank you again for your effort. I would like to know if it is possible to implement something like Heart Touch feature of Polar, i mean, change screen view or turn on light, take a lap... just getting the watch close to the chest transmitter. Thanks in advance.
We don't have a feature quite like this right now, but there are some possibilities.
The closest thing currently available is the onEnterSleep() and onExitSleep() functions available only for watch faces, but they're fairly limited. onExitSleep() is called when the watch is raised to check the time, and can be used to do something like draw a second hand (in sleep, the watch faces only update once per minute).
Perhaps we could do something similar for use in apps, data fields, etc. I'll file your feature request, including your suggestion for a Heart Touch-like feature.
If you wrote a watch app, would it be possible to pair the Heart Rate strap using the Generic ANT Channel and then use rssi (Class: Toybox::Ant::Message) to monitor the proximity between the watch and the HR strap emitter?
I haven't looked into this in any detail, but it strikes me that there might be enough information there to pull this off.
