Negative Heartrate in 1.5RC3 using HxM

[GoogleCodeExporter]

What steps will reproduce the problem?
1. nothing special, just testing new version
2. walked 5km @ 6.3km/h
3. in the middle of walk, i tested sensor data and it marked negative, it was 
ok in the beginning

What is the expected output? What do you see instead?
The expected output is heartrate between 120-145 (my hr brisk walking), but i 
got -100, and other negative numbers

What version of MyTracks are you using? On what version of Android? On what 
phone?
Cyanogenmod 7.0.3, MyTracks 1.5RC3 on NexusOne

Please provide any additional information here:

i think it is reporting negative number because my HR>128 and you are using a 
signed byte to represent it? i put here the exact site in my  TCX export where 
the HR changed to negative:
