Post Receiving BT messages via Processing
i have successfully connected my nxt to my pc via the Processing scripting language and its bluetooth library. I was able to send messages successfully from the nxt to the processing environment and parse them, however any message i send back to the NXT doesnt seem to be receiving properly.

i am using the cCmdMessageRead and cCmdMessageGetSize function to receive on the robotC end, however the receive buffer always seems to be zero. additionally, i believe i am formatting the bytes correctly on the PC end, so the NXT would receives them correctly:

byte1: 0x00
byte2: 0x09
byte3: mailbox
byte4: size of message - 1

however i still have no luck. does anyone have experience with nxts and the processing bluetooth library, or come across a similar issue when trying to receive a message form the pc? thanks
