I use a sp. conection with cayenne is ok, but after sending the data, there is a reset of the soft.

which device you are using and can you share the code you have used?

what does this code do? can you comment it out and check if you have the same issue.

I collect data on the port serie, I process them and I transmit them in wifi

6

does this work for you without the cayenne code added?

Your problem is at while ( mychar != '*'); There’s no way to exit that while loop and the watchdog timer is being triggered and resetting the device.
