ESP32 BLE connection issues

I’m trying to get BLE to work for esp32.
I have Arduino 1.8.8
Have followed this guide to update esp32 core:

espressif/arduino-esp32/blob/master/docs/arduino-ide/windows.md

## Steps to install Arduino ESP32 support on Windows
### Tested on 32 and 64 bit Windows 10 machines

1. Download and install the latest Arduino IDE ```Windows Installer``` from [arduino.cc](https://www.arduino.cc/en/Main/Software)
2. Download and install Git from [git-scm.com](https://git-scm.com/download/win)
3. Start ```Git GUI``` and run through the following steps:
    - Select ```Clone Existing Repository```

        ![Step 1](win-screenshots/win-gui-1.png)

    - Select source and destination
        - Sketchbook Directory: Usually ```C:/Users/[YOUR_USER_NAME]/Documents/Arduino``` and is listed underneath the "Sketchbook location" in Arduino preferences.
        - Source Location: ```https://github.com/espressif/arduino-esp32.git```
        - Target Directory: ```[ARDUINO_SKETCHBOOK_DIR]/hardware/espressif/esp32```
        - Click ```Clone``` to start cloning the repository

            ![Step 2](win-screenshots/win-gui-2.png)
            ![Step 3](win-screenshots/win-gui-3.png)
    - open a `Git Bash` session pointing to ```[ARDUINO_SKETCHBOOK_DIR]/hardware/espressif/esp32``` and execute ```git submodule update --init --recursive``` 
    - Open ```[ARDUINO_SKETCHBOOK_DIR]/hardware/espressif/esp32/tools``` and double-click ```get.exe```

I’m getting this in the serial monitor:

[550322] BLE connect
[552251] Ready
[562218] BLE disconnect
[562218] Disconnected

I get can’t connect error in the BLE widget

Phone is Samsung s8+
Do I not use the pairing on the phone as when I do it removes the blynk device from the BLE widget in blynk?

Thanks
Paul

I havent understand your problem, Paul.
Do you have a problem with a blynk-widget or with a bluetooth-connection?

With the widget connection to the BLE on a esp32

I also have problems with the BLE connection since I updated the app.
With version 2.26.7 it works fine.
