After playing around with ESP8266 using Espruino, I thought to give ESP32 a shot. After successfully flashing the Travis cutting-edge build, I tried to connect to the board using the Espruino web ide, which either gives me this endless log of recurring error
or show this error
As suggested in the docs, I also tried another tool to connect to ESP32, RealTerm (seems that cutecom and minicom aren't for Windows), which shows similar log of errors.
Any guidance will be appreciated.
