I'm a little confused on how I would interact with a bluetooth device on my Raspberry Pi 4. I have a four probe cooking thermometer that I'd like to read tempatures from and then make a web interface and save my data points. Before I even begin to read data or choose a language I thought I'd try to pair the device with my pi 4.

I've tried the following

sudo bluetoothctl
discoverable on
pairable on
agent on
default-agent
scan on
pair CD:89:7A:45:32:FB
Attempting to pair with CD:89:7A:45:32:FB
[CHG] Device CD:89:7A:45:32:FB Connected: yes
Failed to pair: org.bluez.Error.AuthenticationFailed

I can pair the device to my Windows laptop and my Android phone without issue. Neither required a pin or any other authentication.

I did try to "connect" to the device from my Pi with the following results

[bluetooth]# connect CD:89:7A:45:32:FB
Attempting to connect to CD:89:7A:45:32:FB
[CHG] Device CD:89:7A:45:32:FB Connected: yes
Connection successful
[bluetooth]# trust CD:89:7A:45:32:FB
Changing CD:89:7A:45:32:FB trust succeeded
[bluetooth]# pair CD:89:7A:45:32:FB
Attempting to pair with CD:89:7A:45:32:FB
[CHG] Device CD:89:7A:45:32:FB Connected: yes
Failed to pair: org.bluez.Error.AuthenticationFailed
[CHG] Device CD:89:7A:45:32:FB Connected: no

After connecting to the device I tried to monitor hci0 with no success

$ sudo rfcomm watch hci0
Can't bind RFCOMM socket: Address already in use

So I guess I have two questions

1. How do I successfully pair my pi 4 over bluetooth to this device?
2. After I pair it, is there any quick and dirty ways to read values from it at the terminal to verify it's working?

Updated with the output of list-atributes

nRF Connect shows this device as a BLE device

Another edit, I think I'm nearly there:

var deviceGUID = 'CD:89:7A:45:32:FB'
var primaryServiceGUID = '1086fff0-3343-4817-8bb2-b32206336ce8'
var characteristicGUID = '1086fff1-3343-4817-8bb2-b32206336ce8'
async function start() {
        const {createBluetooth} = require('node-ble')
        const {bluetooth, destroy} = createBluetooth()
        const adapter = await bluetooth.defaultAdapter()

        console.log('Connecting')
        const device = await adapter.waitDevice(deviceGUID)
        await device.connect()

        const gattServer = await device.gatt()
        console.log('Services')
        console.log(gattServer.services())

        const service1 = await gattServer.getPrimaryService(primaryServiceGUID)
        console.log(service1)

        const characteristic1 = await service1.getCharacteristic(characteristicGUID)
        const buffer = await characteristic1.readValue()
        console.log('Buffer:')
        console.log(buffer)
}

start()
