ESP32 WIFI and BLE power status

Hi all,

Regarding the esp32 on a tinypico board, I am wanting to understand a couple of things related to both wifi and ble control.

1.) How can I do a status check on whether both the ble and wifi radios are powered/switched on?

2.) Is WiFi.mode(WIFI_OFF); and btStop(); the best way to turn off both radios?
