User description in pc-ble-driver-py

[gnf]

When trying to add a user description to the BLEGattsCharMD() I get this error:

TypeError: in method 'ble_gatts_char_md_t_p_char_user_desc_set', argument 2 of type 'uint8_t const *'

This is a code snippet causing this error:

props = BLEGattCharProps(notify=True, read=True, write=True)
desc_md = BLEGattCharProps(read=True)
user_desc = bytearray([1,2,3])
char_md = BLEGattsCharMD(char_props=props, desc_md=desc_md, user_desc=user_desc)

The error is on this line in ble_driver.py:

char_md.p_char_user_desc = util.list_to_char_array(self.user_desc)

(See https://github.com/NordicSemiconductor/pc-ble-driver-py/blob/v0.15.0/pc_ble_driver_py/ble_driver.py#L1267)

Any ideas?

Which Python and OS versions are you running this on? I'm getting an error after a few seconds:

Fatal Python error: could not acquire lock for <_io.BufferedWriter name='<stdout>'> at interpreter shutdown, possibly due to daemon threads
Python runtime state: finalizing (tstate=010BEDC0)

Oh, that didn't look too good. I am running Ubuntu 20.04.2 LTS, Python 3.8.5.

Edit: And just to be clear, the version of pc-ble-driver-py is 0.15.0

In my other issue there is also garbage showing up. Maybe these two issues are related: devzone.nordicsemi.com/.../device-name-shows-garbage-using-pc_ble_driver_py
