Hi there, I am building a device that will attach to shopping carts, that detects when it is within 6 feet of another device, and alerts the users. My original plan was to use two HC-05 bluetooth devices, do a AT+INQ command, and get the RSSI signal strength, to calculate distance. But the devices need to be in "master" mode to do this command. Does this command only return "slave" devices? Or is there a way to have other "master" devices appear when I do this command?
Thanks,
John
