Simulink External Mode Timed Out
4 ビュー (過去 30 日間)
Hi, running my Simulink model in external mode will yield the following error:
Error occurred while executing External Mode MEX-file 'ext_comm': Timed-out waiting for second connect response packet.
The model involves transmitting three different CAN messages from an Arduino board - please see the attached image for reference.
I've spent ages troubleshooting this to no avail, here's what I've tried so far.
- Building and deploying the model is fine and does not result in the error. However I would like to monitor and tune parameters live.
- Reducing the number of messages (i.e. sending only a single CAN-ID) will not incur the error.
- Changing model baud rate does not solve the issue - I am running a genuine Arduino with ATmega16u2.
- Changing the model explorer 'configuration' does not solve the issue.
I am approaching memory limits of the Arduino (circa 85% program and data) with 'Monitor and Tune' but am not exceeding this.
Any help would be greatly appreciated. The model should otherwise work, but feel free to make suggestions for improvement.
