BLE connection problem

DragonAnger

Hi,

I'm using sdk12.3.0 ble_app_uart.

My problem is BLE connection.

Sometimes(almost 50%)I tried to connect BLE but fail and I have to connect again.

I don't know why.

This image is messages that I captured when connection failed.

What is the problem?

Thank you for reading my question!

    Thanks for your answer! BLE device is not paired or bonded. And If device is paired or bonded, I need software solution. Because it didn't happen always. And I tried to your code, It didn't work. I changed RX_PIN_NUMBER and TX_PIN_NUMBER to 5 and 6 (default number is 11, 9) to connect UART with my board. Is that something to do with? Because this problem didn't happen before that. Again, Thank you for answering my question!
