Hi there,

I was wondering of there was any possibility of manipulating the connect function message to change the MAX_DTO and Protocol Version. I'm currently sending the message FF 00 00 00 00 00 00 00. I've been looking at the data being sent from a program that successfully connected and it has sent FF 00 00 00 40 00 08 08. What parameters would I have to change in order to mimic the message.

Thanks in advance!

Hello,

You are comparing a master request and a slave response. The request has two bytes of information while the response has 8. Please refer to the XCP documentation from ASAM for more information.

Ok great. It's on the XCP Protocol Part 2. I've been analyzing the signals being sent using PCAN-View and there doesn't seem to be any TX messages. I'm only seeing the RX message attached when I press Connect Slave

Hello,

note that in your case PCAN-View is a "listener node" (it is not sending the requests), so for it all messages are Rx!
