How to use COM.X Sigfox with M5Stack and M5Core2
takero last edited by
I purchased M5stack Basic and Core2.
I want to connect COM.X Sigfox to this and communicate with sigfox.
So I installed the Arduino IDE, USB serial driver, board definitions and libraries on my PC. And
I tried to write a sample sketch to get ID / PAC information to M5stack.
M5stack Basic was successful.
The following error message was displayed on M5stack Cors2.
File "esptool.py", line 3682, in <module>
Serial port COM3

Failed to execute script esptool
When Basic is connected to the PC, it is connected to com3 in Device Manager, but when Core2 is connected, it is com7. Something is wrong.
What should I do? please tell me. Thank you.
