Board:custom board Mesh SDK: V1.0.0 IDE:SEGGER Embedded

Problem a： When I test the steps specified by “Interactive PyACI”, there is A certain probability of Provisioning failure.When the serial port printed "EcdhSecret: {'context': 0}",the program will blocking untill Provisioning link closed.I want to known why?

   serial prot log:
          1.Link established
          2.Received capabilities
          3.Number of elements: 2
          4.OobUse: {'context': 0}
          5.ECDH request received
          6.EcdhSecret: {'context': 0}
          7.Provisioning link closed

Hi Beike,

Which firmware you run on the provisionee ? Could you post the full log ?

How often do you see the issue ?

[Beike]

The probability of occurrence is 30%

Sorry for the late reply, Hung has been travelling. Is this still a problem? Could you try with Mesh SDK v1.0.1? Are you following example here? Your logs doesn't look the same.

Hi Petter,

I got the same result when I followed the Provisioning example of Interactive PyACI page.

From the log, it seems the provision sequence can not be completed.

Could you give me some comment how to debug this issue ? Thanks.

    To control your device, use d[x], where x is the device index.
    Devices are indexed based on the order of the COM ports specified by the -d option.
    The first device, d[0], can also be accessed using device.

    Type d[x]. and hit tab to see the available methods.

Hi Herry, 

 

We have updated the interactive py aci in Mesh SDK v2.0. I would suggest you to test with the new SDK and let us know if you still see the issue.
