PEAK CAN reading sent message
Posted: Thu 2. Apr 2020, 09:06
Hello,
I have a severe problem with the PEAK CAN dongle and Visual Studio C++. At random occasions the dongle reads the last sent message instead of the actually received one.
To clarify:
1) I send a message request with
2) I do a to receive the answer to the request.
Mostly the answer is received as normal. But sometimes the answer is not received. Instead the message that was last sent is given back by the p_PCANBasic->Read. There are only the master and slave on the bus. In a trace of the communication I can see that the messages on the bus are correct. Still the message received is not correct.
What could be the reason here??? There must be a bug in the PCAN BASIC driver. Am very thankfull for any hint as this problem is currently delaying production. If it can not be fixed I will have to eliminate the PEAK dongles and make an own solution what would cost more time.
