Only the IP address is shown for unrecognized network boards

[kittaakos]

Describe the problem

This is the follow-up of #1327.

Arduino IDE 2.x shows only the IP address of connected but unrecognized boards. Before #1327, network boards not recognized by the Arduino CLI were not listed in the "Board Selector" menu. See the changes here and here.

#1327 will remove the above-mentioned filtering, and the Arduino IDE will show all network boards. Unfortunately, the IDE receives insufficient information from the CLI, so the IDE has no chance to show anything else but the IP.

The mdns-discovery is aware of these additional things; hence the Arduino IDE 1.x can enhance the label of an unrecognized network board:

HELLO "ciao" 1
{
  "eventType": "hello",
  "message": "Invalid HELLO command",
  "error": true
}
HELLO 1 "ciao"
{
  "eventType": "hello",
  "message": "OK",
  "protocolVersion": 1
}
START_SYNC
{
  "eventType": "start_sync",
  "message": "OK"
}
{
  "eventType": "add",
  "port": {
    "address": "10.0.1.25",
    "label": "esp32s2 at 10.0.1.25",
    "protocol": "network",
    "protocolLabel": "Network Port",
    "properties": {
      ".": "esp32s2usb",
      "auth_upload": "yes",
      "board": "esp32s2usb",
      "hostname": "esp32s2.local.",
      "port": "3232",
      "ssh_upload": "no",
      "tcp_check": "no"
    }
  }
}

The same information is missing from the Arduino CLI board watch (board list -w --format json):

{
  "type": "add",
  "address": "/dev/cu.usbmodem03",
  "protocol": "serial",
  "protocol_label": "Serial Port (USB)"
}
{
  "type": "add",
  "address": "10.0.1.25",
  "protocol": "network",
  "protocol_label": "Network Port"
}

So the IDE fails to show esp32s2 at 10.0.1.25 and falls back to Unknown 10.0.1.25.

To reproduce

The simplest way is to try it with Arduino CLI:

./arduino-cli board list -w --format json

Expected behavior

Arduino IDE should receive the properties from the CLI discovered by the mdns-discovery.

{
    "properties": {
      ".": "esp32s2usb",
      "auth_upload": "yes",
      "board": "esp32s2usb",
      "hostname": "esp32s2.local.",
      "port": "3232",
      "ssh_upload": "no",
      "tcp_check": "no"
    }
}

Or the IDE should receive the "label": "esp32s2 at 10.0.1.25", from the CLI.

Expected behavior

IDE should receive the properties from the CLI

Looks like the IDE needs the properties. See here #740 (comment)

[kittaakos]

IDE should receive the properties

It's all available 🤦 So the CLI does not block this task.

[kittaakos]

There is one issue: the mdns-discovery response has the expected label: "label": "esp32s2 at 10.0.1.25". The CLI does not provide the desired label. Only the properties and the properties does not contain the label the IDE (1.x) users got used to.

{
  "properties": {
      ".": "esp32s2usb",
      "auth_upload": "yes",
      "board": "esp32s2usb",
      "hostname": "esp32s2.local.",
      "port": "3232",
      "ssh_upload": "no",
      "tcp_check": "no"
    }
}
