Blynk - Controle do ESP32 NodeMCU-32S via Bluetooth (BLE)

hello! I found your video good! Let me ask more, if you lose the wifi wave, blynk cannot log in, if the wifi is connected, why don't you use wifi.
I am thinking, is there any way to use blynk software, if there is wifi, it will be wifi, if I lose wifi then bluetooth.
thank you!

O meu não encontra o esp32 e quando reseta o monitor serial fica só aparecendo umas mensagens, incluindo a de aguardando conexão
