  • I never could get that HM-10 module working, so I replaced it with a new one which worked great on the first try. Oh well. I've gotten a few parts now that are just simply DOA.

    Anyway, next question. When Espruino is plugged in and powered by the computer's USB, I can successfully connect to and communicate back and forth between the Espruino and my iPhone across bluetooth. Based on the tutorial I used (, I've been reading from and writing to Serial1.

    The problem is when I disconnect from the computer and power Espruino from the wall. I can successfully connect to it from the iPhone over bluetooth (I know this because the blinking status LED on pin 24 goes to solid on), but there's no communication going back and forth.

    What is happening?
