Controlling bots with bluetooth

[botmad]

Just my 2pence worth .......

While bluetooth is 2.4 ghz , there are a lot of mobile phnes at the shows and i dont know if you could be in sole control of the robot via bluetooth as i sure it would get mentioned and someone in the crowed would be sure to try and have a go with there phone ... this doesnt happen with the spectrums ...


Just a friendly comment (and something to test against )

Basicly , i like a challenge , i know i could get a spektrum system for the same price , but thats no fun.

when you pair with a bluetooth device , like wifi you have a pre shared key , and as long as no one in the audience knows this , they can t control my bot, even then they would have to guess at my control protocols, as its pear to pear so hey cant monitor it.

I ahve come across that thread before , but with that setup i cant have the degree of control i need and i am limited to 2 channels.

I would like to cut out the laptop, as its just too much to go wrong and too much to setup, so now ive established that its within the rules, does anybody know if its possible to create a wireless serial link between 2 adapters, cuz no where on the interent says that you can get 2 adapters to connect and pass serial information without a pc in there somewhere.

Sussex models is selling the Planet 5 2.4Ghz Transmitter & Receiver Set for £36 which they describe as:
Advanced 2.4GHz 5-channel professional transmitter and receiver
Includes
2.4GHz 5-channel professional transmitter
2.4GHz micro 6-channel receiver

I know nothing about this gear, just saw it on their site, but for £36 it has to be the cheapest 2.4 GHz control you are going to get.

It's sixteen pages of thread I know but it does get a bit more advanced as he gets to know the software and also gets manages to get it set up with the Wii nunchuck controller. That said sure there will be a lot of mods to any software you get but it's a good start.

Pete,

Spektrums use bluetooth technology basically there's nothing special in them. It's the same type of thing you get with either a wii controller or an xbox 360. It's just a 2.4ghz module on a circuit board, if someone wanted to they could simply take the rx apart read the software and stick it on another module. That would obviously not be particularly legal but is not really that hard.

If you are going to buy one of these, ask first if you can test its failsafe capabilities. When you switch off the transmitter the robot must stop working and a lot of these transmitters the channels will just continue doing what they were doing until the signal comes back.

my escs have built in failsafes

[joey_picus]

The failsafes still won't kick in if the reciever keeps giving out the last valid signal it gets, you need the reciever to either have built in failsafes or not give out a signal when it loses contact with the Tx.

thats the plan :P
