I've just received yesterday wild thumper 6WD with T'Rex controller, DAGU bluetooth module and 6DOF robotic arm .

Help: Weird HC-05 behavior

Hi. I'm having problems with the HC-05 and I hope someone can help. I've wired it up to an FTDI USB<->Serial connected to my PC just to test it out.

1. If I send it an AT command, it seems to enter an infinite loop where it sends OK back. If I power off & on, send it AT+VERSION, it enters an infinite loop sending the version info and OK. Basically, any AT command gets infinite responses.

Cheap yet relative accurate signal sensors

Thanks for visiting the nuthouse!
Anyhow, I'm trying to figure out a relatively cheap, yet accurate, distance-sensative sensor.

So, the end question is, does anyone know of a sensor type that can be mounted on an arm,
that moves from 0 degrees to 180, 6 inches apart, to detect my location by something I'm carrying?

-From what I've read, the standard RFID chips don't usually even cover 5 feet.
-I've tried bluetooth, but the sensor strength fluctuates too much for a clear reading,

Wireless surveilance system..

Hi, all, this is a bit of a random night post, but, i need your help...i need a cheap way to make a surveilance system.. 

I have a CCTV camera module that looks like that, and no, it's not wireless, doesn't have a receiver. It only has Audio/Video cables and a power cable. Is there a cheap way to make this work using bluetooth? I only need to spy from 5 meters away. Btw, i want to be able to receive the video from my laptop.
