UDS connection via CAN ,self.tp.recv time out waiting for message

[saheelsikander]

Hello Richard,

i was trying python-ids , but unfortunately with the documents and example provided i am not able to establish connection, code snippet and error log is shown below,
appreciate your help in solving this issue .

Code:
import can
from uds import Uds

test1 = Uds(transportProtocol="CAN",reqId=0x600, resId=0x650, bustype="vector",device="CAN",appName="pythonUds",channel="0")
#print(dir(test1))
esnRaw = test1.send([0x22, 0xF1, 0x8C])
print(esnRaw)

This sends the request for Ecu Serial N

Error:
Traceback (most recent call last):
File "D:\Python_Learning\Diagnostics.py", line 7, in
esnRaw = test1.send([0x22, 0xF1, 0x8C])

response = self.tp.recv(self.__P2_CAN_Client)
File "C:\Users\ssikander\AppData\Local\Programs\Python\Python38-32\lib\site-packages\uds\uds_communications\TransportProtocols\Can\CanTp.py", line 340, in recv

Hi. First off you're using the ID's that we put in as an example for the Embed E400 bootloader which are atypical for most automotive applications. Usually most vehicles have ReqID and ResID in the range 0x700 - 0x7FF. Do you know what the IDs are of the module you're trying to communicate with? Typically for most cars the PCM (engine ECU) is ReqId: 0x7E0 and ResId: 0x7E8 Could you give me more information on your ECU / network setup?

Hello Richard,
I am trying to connect to infotainment ECU with ID's

I am facing the same issue. Here am code example:
rawEcu = Uds(reqId=0x18DA03F5, resId=0x18DAF503, transportProtocol="CAN", interface="peak") # baudrate="250000"
esnRaw = rawEcu.send([0x10, 0x01])

Furthermore, in CanTp.py last line 460, I did following modification for the extended message id:
self.__connection.transmit(transmitData, self.__reqId, extended=True)
