I’m having real issues to connect the Spark Core to my computer. More precisely, using the Serial cannot be done. I tried to followed every tutorials I could find on the doc and this forum and it’s still impossible communicate via serial (so obviously configure the wifi).
I can put the Core in DFU mode and update it, working. When I type the commands
particle serial list, it found
1 device connected via serial, COM3 - Core. When I do any other configurations, it’s always end up with a
Error Opening COM3 - Access denied.
My first guess was the Serial port is opened somewhere else; The software
processxp (or any other serial monitor) find it busy.
Do you have a clue why it behave like that ?
