While messing around with my Polar H7 trying to figure out how to read real time heart rate information I inadvertently overwrote the device name. I didn’t even realize that this was possible, but apparently it is. When running an hcitool lescan I would no longer get the device name listed. I was getting a weird character. This made life a bit harder. On my Android devices when scanning for the device I’d just get a blank name.

I recently picked up the Polar H7 Heart Rate Sensor (Bluetooth Low Energy). The long term goal is to connect up the sensor to my HTPC running XBMC so that I can see my heart rate on the screen while I work out. I usually work out to music playing on the HTPC or watching P90X videos. So, it’d be nice to be able to see the heart rate information real time as well as record it in a file/db for historic purposes.
