You shouldn't need to use hcitool nor gatttool for the heartrate
profile. Instead, it should be enough to register a Heartrate Watcher
through the HeartrateManager D-Bus interface (see doc/heartrate-api.txt).
There's also a python script that will do all this for you in
test/test-heartrate. I've been able to use the script successfully with
my own LE heartrate device.
