Cannot Start assetDataTutorial

1

Hello,

I’m working through the tutorial found here: 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 -

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
