STM32WB09KE ble disconnect with 0x08 reason

[tiennguyen]

hi ST support team

I am designing a circuit using the STM32WB09KE chip.

However, when running the BLE_p2pServer example program from the package STM32Cube_FW_WB0_V1.1.0 and using the ST BLE Toolbox app (on iphone) to connect, I encounter a continuous disconnect issue.

I have changed the UART1 pins and am not using the LSE compared to the example code.

Could you help me resolve this problem?

So have you looked-up what reason 08 means?

Does it work on an ST board?

[tiennguyen]

0x08 meaning connection timeout

I don't have an ST board, so I haven't been able to test the sample code on it. I'm not sure if my circuit design is causing any abnormalities

Which is exactly the reason for trying it on an ST board!

Or, at least, some other known-good board.
