Description
HI @pylessard,
thank for publishing this great work.
I'm traying to use your code but I get this outputs (see below):
Output:;
Exception has occurred: AttributeError
'Params' object has no attribute 'wait_func' and no dict for setting new attributes
File "C:\python-udsoncan-master\python-udsoncan-master\udsoncan\beispiel3.py", line 46, in
stack = isotp.CanStack(bus=bus, address=tp_addr, params=isotp_params) # Network/Transport layer (IsoTP protocol)
AttributeError: 'Params' object has no attribute 'wait_func' and no dict for setting new attributes
I checked the file protocol.py and the value wait_fun does exist!
cann you please support here. thanks in Advance!
