I2C Error when WiFi Disconnected/ Connected


On Jetson Orin Nano Devkit, when I’m using an I2C device and running the ros node for it, I get the below error when the WiFi is connected/ disconnected. I have to relaunch the node for it to run.

1712405924.981101 [0] tev: ddsi_udp_conn_write to udp/ failed with retcode -1

Is this expected behavior or should some settings be changed to prevent this error?

It looks expected since network is disconnected, and on-going UDP streaming suspends. It should be revived if the network is back.
