Stop serial debug in esp8266

[igutier]

I need to stop the esp8266 to send debug info through the serial port is there any way to do that?

Hi,

Normally you should be able to use the regular os_printf()-like functions and the gdb stub will wrap that output so that gdb (and VisualGDB) will recognize it properly.

However, as many other things on ESP8266 and ESP32, this may not always work.

fwiw – I have been able to successfully send os_printf(“message”) values to the serial port from the ESP8266 when programmed with VisualGDB.

Reminder that if not otherwise initialized, the default port speed is 74880 (8N1 / no flow control); this can be very useful when debugging as there are system messages always printed at powerup / reset time.

I suggest also the very first thing to send is a message with the exact version you are testing, as I have had occasion when it would appear that code was sent to device, but not.
