nRF5 Mesh SDK Serial Example Interactive PyACI Provisioning problem

Question

Hello, 
 I am new to nrf5 mesh. I have setup my system based on Nordic's documentation and was evaluating Serial Example with Interactive Py script. 
 My setup consists of: 2 no. PCA10028 V 1.0.0 dev boards, Windows 7 PC, with Python 3.6.4 (32-bit) installed. I have generated "serial_nrf51422_xxAC_s130_2_0_1.emProject" with CMake and flashed both the boards with its HEX files via SES IDE. 
 I am running the interactive_pyaci.py script am trying to do Provisioning as per the doc. But I am getting the following error: ERROR - COM5: OobUse: ERROR_INVALID_LENGTH 
 Please see the log messages below: 
 $ python interactive_pyaci.py -d COM5 COM6 -b 115200 --no-logfile 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.

 I am following the Interactive PyACI documentation present in the SDK. Please let me know where am I going wrong. 
 
 Thanks

Hi rohandey87, 
 It seems that there is an issue in the release where some of the provisioning APIs has been changed, but the provisioning python script was not updated for this. It is fixed internally and will be a part of the next release. I've attached a diff that should fix your problem.

NOTE: You actually only have to apply the last part of the diff, related to `provisioning.py`. The rest, you can do with `ninja serial_pyaci` or `make serial_pyaci` to re-generate the (de-)serialization code. 
 Hope this helps, Thomas
