I'm using the Vector box VN1610, and i want to establish communication with an ECU to read a DID (service 0x22)
I get an exception when initializing the communication.
Uds_Channel = Uds(resId=BSC7_resId, reqId=BSC7_reqId, transportProtocol="CAN", interface="vector", appName="pythonUds", channel='0')
File "C:\Users\hba12\AppData\Roaming\Python\Python39\site-packages\uds\uds_communications\Uds\Uds.py", line 43, in init
self.tp = tpFactory(self.__transportProtocol, configPath=configPath, **kwargs)
File "C:\Users\hba12\AppData\Roaming\Python\Python39\site-packages\uds\uds_communications\TransportProtocols\TpFactory.py", line 37, in call
return CanTp(configPath=configPath, **kwargs)
File "C:\Users\hba12\AppData\Roaming\Python\Python39\site-packages\uds\uds_communications\TransportProtocols\Can\CanTp.py", line 96, in init
self.__connection = canConnectionFactory(self.callback_onReceive,
