Revision history [back]

The rosserial_python node will automatically resync topics with the Arduino whenever it A) starts up, or B) decides the connection has failed. This is currently done by using the ros::Time synchronization call as a keep alive, if no calls show up in a given time, the connection is restarted (this can take up to 5-10s currently).
