 | | Connect BT devices to the NXT without a passkey?
|
|
Is it possible to connect BT devices to an NXT without using a passkey? The device I'm trying to use (a Nintendo Wii remote) doesn't use passkeys, AFAIK, since when I connect it to my PC I skip the pairing process. (18 years ago, 28-Dec-06, to lugnet.robotics.nxt, lugnet.robotics)

Maybe a cheap sollution, but if I have to draw a sine or cosine I wouldn't calculated. Well, I will calculate it once and put it in a table. Then draw the sine & cosine from the calculated coordinates from the table. Really fast. And, euh, nobody (...) (18 years ago, 23-Dec-06, to lugnet.robotics)
