Hello,

I have issues using MultiArrays in rosserial (0.3.0), on Groovy and Electric. This is due to the fact that it seems rosserial doesn't handle unsigned variables, and MultiArrayDimension (used in all multi array std_msgs) use unsigned for both size and stride, plus I need to use UInt8MultiArray (array of unsigned 8-bit integers), which makes all the data unusable on the hardware side.

Does anyone has problems using unsigned variables in messages over rosserial ?

Thanks, Cyril
