(...) John Barnes and others have been working on that. He has out a beta of a "Nxt Byte Code" (NBC) assembler, and he's dug into a *lot* of firmware and software details. See the following (& John's website) for more details. (URL) not as sure (...) (19 years ago, 4-May-06, to lugnet.robotics)

(...) Yes, that's a tough one... (...) I've played around with a few ideas using bluetooth. In addition to the NXT->NXT remote, I wrote a program for my Bluetooth enabled PDA using eVB. Jim Kelly actually has a screenshot in his blog (URL) under (...) (19 years ago, 4-May-06, to lugnet.robotics)

(...) Yes. NXT1 will be connected via connection 0 from NXT0 NXT1 will be connected via connection 1 to NXT2 NXT1 will be connected via connection 2 to NXT3 NXT1 will be connected via connection 3 to NXT4 NXT1 can send a message to connection 0,1,2, (...)

(...) Steve, your remote is pretty cool. It’s a great idea if you have more than one NXT. I checked with my purchasing manager (my wife) and I don’t think my request for capital expenditure will be approved for more than one NXT this year. With that (...)

(...) A little - the next question of course is: Can NXT1 be both slave (to NXT0) and master (to NXT2, NXT3, NXT4) at the same time? Or does that require sneaky protocol to switch between the 2? ROSCO (19 years ago, 4-May-06, to lugnet.robotics)

(...) Dave, I don't know a whole lot about BT (beyond the little I've found out because of this project), but your assessment is correct. The protocol is implemented according to BT spec, so all communication is done through master-slave (...) (19 years ago, 4-May-06, to lugnet.robotics)

(...) Quite muddy! Why only three connections and what about specification adherence? Are they trying to limit its potential applications or were they just trying to get out a production-ready implementation? In other words are there plans for an (...) (19 years ago, 4-May-06, to lugnet.robotics)

(...) I can't speak for the NXT, but knowing that it has BT, and should be adhering to the specs, then the answer would be yes. The master-slave communication is coordinated via time slots within a piconet. This would avoid message collisions. In (...) (19 years ago, 4-May-06, to lugnet.robotics)
