Error -52 "invalid connection" only when OTHER modules transmit?


#1

I am trying to run an interface tied into a CANbus line with established traffic. The module itself works fine, with no problems, and transmits 2 to 3 messages in a loop. However, if I connect it to the application, i get a second or so of messages, and then it stops transmitting. If I reboot the PAC, i get another second or so and then it stops again. I get a “warning” message -52. This is only when connected to the main network. If it is the only thing transmitting, it works fine. Its only when there are other CANbus messages on the line.

update: added a check flag for com handle. communication stays open, warning message goes away, but transmission still drops out.

You’ve checked Baud Rates right?
