Testing bluepy

[PrzemoF]

I'm quite sure it's not an issue with bluepy, but I need confirmation. That's a discovery session with a heart rate sensor:
pi@occberry ~/bluepy/bluepy $ sudo hciconfig hci0 up
pi@occberry ~/bluez/bluez-5.26 $ sudo hcitool lescan
LE Scan ...
90:59:AF:16:93:12 (unknown)
90:59:AF:16:93:12 JipulseHrRateBT4.0
[..]
pi@occberry ~/bluepy/bluepy $ sudo python btle.py 90:59:AF:16:93:12

Does it look OK conparing to other BLE devices?
That sensor doesn't work properly with android, so I guess that the vendor at least partially ignored BLE specification. P.S. Running the bluepy-helper doesn't make any difference.

Hi Przemo,

The 'comerr' errors are what I'd expect if you're calling read() on characteristics which don't allow reading. It looks like this got fixed in pull request #32 (specifically, commit 721dc48), so I'll close this issue.

Cheers
Ian
