Hi Community,
following setup: PC with *roscore* and *rosserial_embedded serial_node tcp* with a tiny *rosserial node* on an embedded linux board. So far so good, everytinh is working.
**Problem:** If i have to restart roscore/rosseriay on my PC, i also have to restart my rosseria-node at my tiny linux board - **by hand**.
**Question:** Can i anyhow configure my rosserial to reestablish this communication?
I have tried to check the return value from nh.spinOnce and rerun nh.initNode(); but with out any progress.
// within main loop
int check = nh.spinOnce();
if ( check == 0)
printf("ros is okay");
else
{
printf("ros is NOT okay");
nh.initNode();
}
Is there the possibility to keep one rosserial node on a dedicated device alive while roscore/rosserial_python is down and later reconnect to it? Maybe the missing timestamps are a problem?
Every helping hand is welcome!
