ESP32 Forum

I am using esp32 development kit, and trying to check ESP-MDF light example with that.
I am facing that device stuck in Yellow blinking.

I am trying to run with mesh app for android.
App shows me BLE disconnected after 10% of progress.

Here are the logs

Any sugession?

Thanks.

Hi tushark,

If the App fails at 10%, then it means the BLE connection between the devices and the smartphone fails.

Please restart your Bluetooth function on your smartphone and retry.
