BLE client send command

[chrisdev524]

Hi!

It would be great to have a feature not only read values from BLE client devices, but sending commands. I have some BLE key finders and they have a feature to beep if I would like to find them. Now I can only trigger it via app.

Could you extend the myhomeiot_ble_client with a functionality to connect to the device, write command, disconnect if a button is pressed like with ble_client.ble_write?

button:

• platform: template
  name: "Nut alert"
  on_press:
  • ble_client.ble_write:
    id: nut
    service_uuid: "ff00"
    characteristic_uuid: "ff01"
    value: [0x03]
  • delay: 5s
  • ble_client.ble_write:
    id: nut
    service_uuid: "ff00"
    characteristic_uuid: "ff01"
    value: [0x04]

Thank you!
