Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.

Yeah, it's covered in some other posts.
There's no flow control, and at 115200 baud the data can get sent faster than the ESP32/ESP8266 can handle it, so the Web IDE has to artificially throttle it so as not to introduce errors when uploading large functions.
If you look at the log it probably is throttling regardless of the setting you used in the IDE.
IMO ESP8266/ESP32 should just use 9600 baud like every other one of the boards that runs Espruino, but while they don't I have to artificially throttle to near-9600 baud rates or I keep getting support emails from people telling me it's not working :)
