I think in previous versions Espruino's software reset didn't reset the peripherals (like I2C). That'd mean that the very first upload wouldn't work, but after that I2C would stay set up from the last time...
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.
Great! Glad it's sorted...
