iOS info tcp_connection_is_cellular No connected path

pablozandona commented 2 years ago

Description

I need to establish a connection to a device with an STM microcontroller. On android it works fine with the same code.

The socket was created, as shown in the createConnection callback, but on iOS it doesn't send data, and it doesn't trigger an error in on('error'.

Steps to reproduce

Or code:

const socket = TcpSocket.createConnection({
    host: HOST,
    port: 31320,
}, () => {
  console.info(">> CREATED SOCKET");
  socket.write(new Buffer([65, 112, 112, 67, 105, 101, 67, 109, 100, 73, 0, 0, 78, 48, 49, 50]));
});

Current behavior

These messages are shown in the Xcode log:

2022-01-29 19:28:33.938595-0300 appprogramadorcie[500:31121] [javascript] >> CREATED SOCKET

@pablozandona, is the callback from the write() function being called?

pablozandona commented 2 years ago

It wasn't responding because it was sending the wrong byte packet. Sorry for the report.
