| | | (...) The problem (I think; somebody want to prove me wrong?) is that the "master" NXT can send messages to at most three "slave" NXTs, but the "slaves" can not then act as BT masters to still more units. In other words, it seems very very easy to (...) (18 years ago, 11-Aug-06, to lugnet.robotics.nxt, FTX)

| | | | | It's good that people are interested! With the RCX couldn't you just have a robot broadcast a message to anything that could see the IR signal and was waiting for specific messages to arrive? Can a similar thing be done with BT? Would we be better (...) (18 years ago, 11-Aug-06, to lugnet.robotics.nxt, FTX)

Here's something you could play around with before BF: (URL) by getting your robot to follow the line on the test pad. To answer your (...) (18 years ago, 11-Aug-06, to lugnet.robotics.nxt, FTX)

| | | | (...) As I was working on my ruby-nxt module, I managed to get the nxt to connect to my laptop as both a master and a slave. On my laptop (a MacBookPro) I created an incoming bluetooth serial port and an outgoing serial port on the DEV-B device (...) (18 years ago, 11-Aug-06, to lugnet.robotics.nxt)

| | | | (...) I played around with this a little bit, trying to confirm what I've been told. It is possible to have an NXT connect as either a master or a slave, but not both at the same time. I'm sure this is true. Here's what I did: I took three NXTs with (...) (18 years ago, 13-Aug-06, to lugnet.robotics.nxt)

|
| | | | Here's an idea of how to get more than 3 NXTs connected via Bluetooth (BT). It involves using a PC as a "relay point". I think standards allow up to seven simultaneous connections per BT device. The limitation to three connections on the NXT may be (...) (18 years ago, 13-Aug-06, to lugnet.robotics.nxt)

| | | | (...) My problems with this solution are two-fold. First, NXT-G currently can't send anything back to the PC, as it's not running anything to get the NXT-G message structure (yes, folks could write this... almost certainly will. But likely not me).
