Questions about room assistant and need of help in config

Third party integrations
1

Hello everyone,
Im wondering few things since i installed room-assistant, and im here for help and advise.
Im running room-assistant in a docker container, this is my config:

global:
  instanceName: nano-room
  integrations:
    - homeAssistant
    - bluetoothClassic
    - bluetoothLowEnergy
homeAssistant:
  mqttUrl: 'mqtt://192.168.0.198:1883'
  mqttOptions:
    username: nano
    password: nanonano
  discoveryPrefix: homeassistant
bluetoothClassic:
  maxDistance: 3
  updateFrequency: 0
  addresses:
    - 50:3D:C6:7F:E3:8B
    - C0:6B:55:E6:B3:EF
bluetoothLowEnergy:
  maxDistance: 3
  updateFrequency: 0
  instanceBeaconEnabled: false
  allowlist:
    - E8DB17521BBE

my questions are:

  1. is there a way to make the update of the status of the bluetooth device faster?
  2. i have my bluetooth dongle in a usb extention mostly in the middle of the room (my pc is hide in a closet) and im using a mi band 6 for the low energy part, but when i go a little far to the wall, im out of the room (for the room-assistant) plus if i put my band under a pillow, Im out too
  3. what would you improve in this config?
  4. how i know what version of room-assistant Im running (i bet is the last release for docker, if this help in anything)?

Thanks everyone and i hope someone can answer
