Hello, I’m working through the tutorial found here: [legato.io/legato-docs/latest/howToAirVantageExchangeData.html](http://legato.io/legato-docs/latest/howToAirVantageExchangeData.html) I’m using a WP8548 on MangOH Green with 07.12.09.00 firmware and Legato version 16.10.3 I’m successful with all steps except when I try the final step of: # app start assetDataTutorial I don’t see the app start, and this is the log output - Jun 9 17:56:50 swi-mdm9x15 user.info Legato: INFO | supervisor[473]/supervisor T=main | resourceLimits.c SetRLimitValue() 282 | Setting resource limit maxCoreDumpFileBytes to value 102400.

Hi @mxwidmer, are you sure the version of Legato on your target (so 16.10.3?) matches the version of the sources/SDK you are working with? According to `Client (uid 0 'root', pid 24606) disagrees with server (uid 0 'root', pid 530) on protocol ID of service 'assetDataTutorial` I would that you built your app against a different version, resulting in this error. ---

Hello CoRfr, Thank you very much for the recommendation! The SDK was at version 16.07, after upgrading to 16.10 and rebuilding the app components I was able to get the application to start successfully. Thanks again, Max
