The problem persists.Here is a simpler example with my console return. We notice that the event on the serial reception does not work anymore after a writing.

Code Esp32 - Esrpuino

Serial2.setup(9600, {rx:D16,tx:D17});

Serial2.on('data', function(data) {
  console.log("<SERIAL> "+data.toString());
  Serial2.write("Hello from Esp32\n");
});

Console

TEST_1
SEND:TEST_1
RECV:Hello from Esp32
TEST_2
SEND:TEST_2
TEST_3
SEND:TEST_3

Can you help me ?

Hello guys !
I'm new on this forum and beginner in using Espruino. I have some troubles with serial comminication. I'm trying to create a bridge between a TCP and Serial, on the Esp32 board (ESP-WROOM-32).

let net = require('net');
let port = 11000;

Serial2.setup(9600, {
    rx: D16,
    tx: D17
});

// Create NET server
let server = net.createServer(function (socket) {

    socket.on('data', function (datas) {
        console.log("TCP RECEIVED:" + datas.toString());
       // Send datas from TCP over Serial
        Serial2.println(datas.toString());
        console.log("SERIAL SEND :" + datas.toString());
    });

    Serial2.on('data', function (str) {
        console.log("SERIAL RECEIVED:" + str.toString());
        socket.write(str.toString());
    });
});

server.listen(port);

The problem is when the function "Serial2.write(...)" is called, there is no longer a receiving event on "Serial2.on('data',..." when I send data to the serial.

Before the calling, it works perfertly, but after there is no more event.

Is there a function for data events after a write? Or do you have the same problem on your Esp32 with Espruino?

Excuse me for my english, it's not my first language :)

Hope you can help me
