    I have tried version 2.02 and found that the problem has been fixed. Thanks everyone :)

    Yes, that's an important detail that I missed from of my original post. I too am seeing that the ESP32 is able to receive ok. Thanks, Arpad.

    Hi,

    I have just come back to a project on Espruino that hasn't received any attention in the last past 6 months or so. I'm having a problem using code that worked on V1.97, V1.98 and V1.99 with Espruino V2.00 and V2.01.

    Configuration of Serial3 (and maybe also Serial1 and Serial2) is being ignored. To come to this conclusion, I have produced the most simple code that exhibits the problem:

    function send() {
        console.log("Sending...");
        Serial3.print("ZZZZZZZZZZZZ");
        setTimeout(send, 100);
    }
    
    function onInit() {
        Serial3.setup(115200);
        send();
    }
    

    Connecting a logic analyser showed the data was actually being transmitted at 9600 baud and sure enough, when I reconfigured the receiver to 9600 baud, I received the characters transmitted by the ESP32.

    I also tried using 19200 baud but the output was still 9600 baud. To be certain I wasn't doing anything silly I have tried this code on the last version I believed it to work on (V1.99) and it does work.

    I am using Serial1 for programming from the Espruino Web IDE so I have not been playing with it's configuration. I have ESP-WROOM-32s mounted on a PCBs so it's not so easy for me to change the pins used. The PCB layout expect Serial2 to be redefined to { tx: D25, rx: D34 } and I'm not getting anything on these pins so I believe that the pin selection is being ignored too.

    I also seem to be experiencing related error messages. I occasionally see this message pop up in the console on V2.01 (not sure about other versions):

    E (59292) uart: uart_read_bytes(1131): uart driver error
    

    And every few minutes it will experience an error that causes it to reboot.

    Is this a known bug? Are there any work arounds?
