Can't connect to the ESP32

[HHavendano]

I try to use the code ,and the app. I can select the Firmware file, but i can select de device.

1. I select the "Chose" button
2. Show me the name ESP32 OTA, and i select it.
3. I wait but nothing happen
4. After 5 seconds, the app closes.

So i can't update the ESP32 for that. Could you help me?

ESP32_BLE_OTA_Arduino/esp32_ble_ota/esp32_ble_ota.ino

Lines 56 to 58 in fa90638

 #define SERVICE_UUID              "fb1e4001-54ae-4a28-9f74-dfccb248601d" 
 #define CHARACTERISTIC_UUID_RX    "fb1e4002-54ae-4a28-9f74-dfccb248601d" 
 #define CHARACTERISTIC_UUID_TX    "fb1e4003-54ae-4a28-9f74-dfccb248601d" 

This service should be listed, after that you can disconnect then use the OTA app
