//Configuration
let tls = false //If using TLS (true or false)
let address = "meshtastic.local" //IP address or host name

//Below is the exact connection protocol used my Meshtastic Web HTTP transport protocol
const connectionUrl = `${tls ? "https" : "http"}://${address}`;
let response = await fetch(`${connectionUrl}/api/v1/toradio`, {
    method: "OPTIONS",
})
console.log(response)

------------------------------------------------------------------------------
If everything is OK, you should see a response like below:

Response {
  status: 204,
  statusText: 'OK',
  headers: Headers {
    'content-type': 'application/x-protobuf',
    'access-control-allow-headers': 'Content-Type',
    'access-control-allow-origin': '*',
    'access-control-allow-methods': 'PUT, OPTIONS',
    'x-protobuf-schema': 'https://raw.githubusercontent.com/meshtastic/protobufs/master/meshtastic/mesh.proto',
    connection: 'keep-alive',
    'content-length': '0'
  },
  body: null,
  bodyUsed: false,
  ok: true,
  redirected: false,
  type: 'basic',
  url: 'http://my_device_ip/api/v1/toradio'
}

------------------------------------------------------------------------------
In case of problems, you should expect something like this
EHOSTUNREACH in the example below means the device cannot be reached from the current server (DNS, firewall, NAT, etc...).

node:internal/deps/undici/undici:14130
