Read characteristic using pc-ble-driver-py bindings

[Martijn Vriens]

Hi all,

I am using the pc-ble-driver-py python bindings to interface with my BLE peripheral.

Based on the heart-rate-collector example I could get a list of all advertising devices, and connect to get a list of all characteristics.

Now I want to read the value from a characteristic, but I don't know how to do that.

Did anyone already manage to do this? Any help would be appreciated.

Hi,

We are adding reading characteristic into the repo. You can have a look at this fork: github.com/.../

One example of reading the battery level is attached here.

heart_rate_collector_ReadChar.py

Thanks, that was the missing part that I needed. I can now read out the characteristics that I need!

Hi,

I needed to do the same, but while running the given example, it shows this error:

File "C:\Python27\lib\site-packages\pc_ble_driver_py\ble_adapter.py", line 234, in enable_notification
raise NordicSemiException('CCCD not found')
pc_ble_driver_py.exceptions.NordicSemiException: CCCD not found

Could you tell me why?

The device I am connected to has characteristics stored in the UUID "0x2A26", How do I access that?
