Hi, I use the adafruit EZ link for the bluetooth connection to remote control my robot. It works fine within 20-25 feet range but once the BT is out of range, I want the robot to stop so that it doesn't go heywired.
Can someone suggest a way the the Arduino can detect the BT connection out of range so that I can code the Arduino to stop any movement?
If you don't have any link status information from the BT device, couldn't you simply implement a timeout?
I have a system for controlling model trains (using nRF24 rather than Bluetooth) which sends a message 10 times per second. If no message is received for more than 1 second the receiver knows to stop the train.
