Rosserial UInt8MultiArray sends wrong data in transfer on Rosserial Jade
When sending an array of unsigned chars over rosserial the data that gets sent over looks the same as when you try to reference arrays right after their memory has been allocated but no data has been initialized. What fixed the problem in the end was using any other multiarray type and making no changes anywhere else. I was wondering if this was a bug with the message type or there is something special you need to do to get the UInt8Multiarray to work?
@dupli: it would be nice if you could include a snippet showing how you are initialising and populating your MultiArray. As @ahendrix mentions,
rosserialdoes things slightly different in some cases, so perhaps we can clear that up.
