This needs to be handle inside BT/Wifi firmware. See  Bug 836516

BluetoothService::ToggleBtAck::Run()
{
  MOZ_ASSERT(NS_IsMainThread());

  // This is requested in Bug 836516. With settings this property, WLAN
  // firmware could be aware of Bluetooth has been turned on/off, so that the
  // mecahnism of handling coexistence of WIFI and Bluetooth could be started.
  //
  // In the future, we may have our own way instead of setting a system
  // property to let firmware developers be able to sense that Bluetooth has
  // been toggled.

As far as I know, Gecko already wrote property for indication purpose. So Android property "bluetooth.isEnabled" had been set, so the wifi util/co-existence util shall be able to check this property value and activate the correct co-existence algorithm from firmware side.
