Hello,

Could you please confirm that is being tested with the new SDK version and the w_uart is not being modified?

Hi,

I recommend using the latest SDK version, it could be found here.

By any chance, have you tried with the w_uart example without any modifications? Is it behaving the same way as previous tested?

Hi，

w_uart routine does not make any changes, using the mobile app connection will be directly disconnected, I also shielded a line of code,。

Hello,

I could recommend using the latest SDK version. Have you tried with the w_uart example without any modifications? Is the same behavior present?   

Have you identified any other circumstance when having the disconnection? I am asking this because a disconnection could be caused by the environment of the test.

Hello,

What is the latest SDK version? Please give me a download link.

The w_uart example is largely unchanged, masking connection events BleApp_StateMachineHandler.

I was in an empty parking lot, with the development board next to the passenger seat, and I tested it.

Hi,

I have been assigned this case.

Could you tell me what example is being used to measure the distance of connectivity? Have you done modifications to the example?

Also, could you please clarify what SDK version and IDE version are you using?

Regards,

Itzel.
