Examples in docs/bluetooth_vehicles.md don't run

[PedroKTFC]

I've been trying to run the examples in docs/bluetooth_vehicles.md and am finding most don't work as documented. For example, to get the Create VehicleBluetooth Instance example to work, I had to update it to:

import asyncio
from tesla_fleet_api import TeslaBluetooth, TeslaFleetApi
from pprint import pprint

async def main():
    tesla_bluetooth = TeslaBluetooth()
    device = await tesla_bluetooth.Vehicles.Bluetooth.find_vehicle(tesla_bluetooth)
    private_key = await tesla_bluetooth.get_private_key()
    vehicle = tesla_bluetooth.vehicles.create("<VIn>")
    await vehicle.pair()
    print(f"Paired with VehicleBluetooth instance for VIN: {vehicle.vin}")

asyncio.run(main())

I'm now trying to get the Pair Vehicle example working for which I'm hitting a brick wall!

It would be very useful if these examples were updated (or clues given as to why they're not working)!

I'll review the documentation and see how I can improve it.

For now you can look at my working implementation in Home Assistant here: https://github.com/Teslemetry/hass-tesla-bluetooth/blob/e5df913b97fc77ac3cec1b85c755f193c4dd060e/homeassistant/components/tesla_bluetooth/__init__.py#L50

As for pairing, as soon as you run that command you need to go tap your key card in your vehicle, otherwise it will timeout. I typically put it inside a loop that keeps retrying.

Thanks. I've been away for a few days and will look at your suggestions asap.

I've made some progress but now getting stuck trying to read data. I've successfully paired with the car but I get the errors in the attached file. Any ideas what the problem is? Is there a recommended way to debug this? My simple code that causes the error is:

async def main():
    tesla_bluetooth = TeslaBluetooth()
    private_key = await tesla_bluetooth.get_private_key("C:/Users/giord/Downloads/private_key.pem")
    vehicle = tesla_bluetooth.vehicles.create("LRW3F7EK5MC428310")
    device = await vehicle.find_vehicle(vehicle.ble_name)
    data = await vehicle.vehicle_data([BluetoothVehicleData.CHARGE_STATE, BluetoothVehicleData.CLIMATE_STATE])
    print(f"Vehicle data for VIN: {vehicle.vin}")
    print(data)

asyncio.run(main())

Another update. I have managed to get a version to read data from my car using the code below for anyone that's interested. I'm running on a Windows 11 laptop using its Bluetooth. It's not 100% reliable - I seem to get lots of errors because of the asyncio but I can live with them as I only wanted to use this to prove data could be retrieved using BLE and what that data was. (I'm working on this https://github.com/PedroKTFC/esphome-tesla-ble as the original no longer seems supported.)

To use this I find I usually have to wake the vehicle first, so I run it with the commented out line uncommented. It wakes the car but then fails. Running it again with the line commented out then usually succeeds in getting the data. I have a loop that collects data several times but that can be amended to whatever number of loops you want.

async def main():

    tesla_bluetooth = TeslaBluetooth()
    private_key = await tesla_bluetooth.get_private_key("C:/Users/xxx/private_key.pem")
    vehicle = tesla_bluetooth.vehicles.create("blah")
    await close_stale_connections_by_address(vehicle.ble_name)
    vehicle.device = await vehicle.find_vehicle(vehicle.ble_name)
    print(f"Device: {vehicle.device}")
    await vehicle.connect(max_attempts=2)
    device = await vehicle.find_vehicle(vehicle.ble_name)
##    await vehicle.wake_up()
    for x in range (4):
        data = await vehicle.location_state()
        print(f"Location data [{x}]:\n {data}:ataD")
        data = await vehicle.charge_state()
        print(f"Charge data [{x}]:\n {data}:ataD")
        data = await vehicle.drive_state()
        print(f"Drive data [{x}]:\n {data}:ataD")
        time.sleep (5)

asyncio.run(main())

Finally, do you know if it's possible to get this data without waking the vehicle?

[Bre77]

The only system you can talk to without waking the vehicle is VCSEC, which has very limited data, like lock, wake, and closure states
