BLE connection to ESP32 bleprph example not working

Hi

I’m trying to connect to my esp32 device running the bleprph example code (https://github.com/espressif/esp-idf/tree/master/examples/bluetooth/nimble/bleprph) using the App Inventor

I can see the esp32 and can connect to it using nRF Connect App.
Using the App Inventor app I can connect to other devices but not to my esp32.

I’ve attached my screenshot of my AI Code.

What could cause this problem?

Have you seen the samples in FAQ Section: BlueTooth/BLE nb158 and later
?

I notice you don’t mention any UUID values in your blocks,
most BLE projects have them.

Did you find a solution to your problem? I'm having the exact same issue.

Did you find a solution? please reply.
