ESP8266-01 flash speed (up)?
Posted: Fri Dec 18, 2015 3:34 pmI have some esp8266-01 modules which can only be flashed with new firmware with 9600 baud. Is there a trick do change the baud rate to somewhat faster?

Posted: Fri Dec 18, 2015 3:39 pmWhen in Boot Mode, it is not the firmware that decide of the baudrate, it is a small bootloader present in a ROM insdie ESP8266 which does automatic baudrate detection and handle almost any baudrate. So, even if the oringal AT firmware is 9600 baud, it should not matter for uploads.

Posted: Fri Dec 18, 2015 3:49 pmAs soon as you put GPIO0 to LOW and doing reset (or power recycle), the firmware present in the Flash is ignored, and bootloader in ROM is executed, therefore uploads can be done at almost any rates.
