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.
