using class methods as callbacks fails for writes about python-bluezero HOT 2 CLOSED

Thank you for the kind words about the library.

From the information you've shared, nothing is coming to mind as to where the issue is. So let me share some information about where to look to get more debug information. Hopefully that will be helpful and yield some results for you.

When the BLE peripheral is created, the following method is registered with D-Bus and is called when a write happens to that characteristic. The method is acting as an interface between D-Bus and your callback. The method takes the values from D-Bus and converts them into Python objects. It then calls the write_callback it was given.

Getting the Python debugger to stop in this function (or adding a print statement) might be useful to see what is happening in your situation.

sudo busctl monitor org.bluez will show you the messages on org.bluez D-Bus. This should show the calls to WriteValue so you can see what is coming from D-Bus.

Finally, it is not obvious to me why you have wrapped your call back in staticmethod. e.g.

write_callback=staticmethod(nodeMeshWifiSSIDChar.WriteValue),

In your method you are using self so I would have thought you needed the object instance passed in. I don't have the context you are using this in so I can't tell if this is a code smell or a bug.
