You just pass an array and give the length, to send it. In theory you can send packets with a size up to 255 bytes (look in this group, the info is in here somewhere), but sending 1 byte has a packet loss of aprox. 1% and 4 bytes aprox. 10%, over (...)

Hi! I read that legOS only declared varibles the first time the program is run. Does this mean I cannot use local variables.
