Reducing the power consumption of classic bluetooth esp32

[bassizlink]

I use the classic bluetooth for compatibility and esp32-wroom-32u. The profile for communication used the SPP. The data is transmitted continuously. I connected an ammeter and measured the current consumption. The maximum during transmission was 100 mA. For me it is very much. for SPP -C 40 mA. How can I reduce the consumption? I use the standard BluetoothSerial example.
