Please provide example for iso15765

[pierreluctg]

Hi @drebbe-intrepid, can you please provide example and documentation on how to use ics.iso15765_receive_message() (and other iso15765 methods)

It is not clear to me how to use the iIndex argument is supposed to be use.

Thank you

[drebbe-intrepid]

I'm working on an example right now, iIndex is poorly named, it is the network id.

@pierreluctg https://github.com/intrepidcs/python_ics/blob/master/examples/iso15765_example.py

I had to fix some things to make this work, I'll be releasing a new version here soon once I cherry-pick back to 802 branch.

@pierreluctg I Just uploaded 2.14 to pypi, example should be fully working now.

[pierreluctg]

Thank you @drebbe-intrepid

[pierreluctg]

@drebbe-intrepid I tried the example using python-ics 2.14 and only the First Frame is received in the RX side. The RX side is not sending the Flow Control and it prevents the TX side from sending the Consecutive Frames.

[drebbe-intrepid]

@pierreluctg I did see this behavior once but was unable to reproduce it. Can you let me know your setup again and console output?

[pierreluctg]

This is the output I get from running https://raw.githubusercontent.com/intrepidcs/python_ics/v802/examples/iso15765_example.py with python-ics 2.14, 2 x ValueCan3 and driver version 3.8.2.111

hmm, I suspect a possible issue with ValueCAN3 and not sending the response. I noticed my example I'm doing that with the FIRE2. I'll swap them around and see if I can reproduce it, but I won't be able to get to it until Monday as I'm out of the office until then.

[pierreluctg]

Thank you @drebbe-intrepid

[drebbe-intrepid]

@pierreluctg I've reproduced this on my side and submitted a bug to our internal tracker. Looks to be an issue with icsneoISO15765_ReceiveMessage() and ValueCAN3.

[drebbe-intrepid]

@pierreluctg I believe this should be fixed now. I had the shifting wrong for the flags and didn't have enableFlowControlTransmission set.

Hi @drebbe-intrepid, confirming that it works now with this latest change.

Before pushing a new release can you look at #18 if that do not involve to much work.

Thank you

[pierreluctg]

Working with as expected latest release https://pypi.org/project/python-ics/2.15/
