Although I still don't see the whole picture, I think that your problem is that
you are using 8 bits for every element.
Now either it's 0:225 or -128 to +127.
So you probably have declared the struct that you send as int8_t[][] array.
Try to declare it as int16_t and don't forget that the default message payload
size is 28 bytes.
