I hooked up a bluetooth module similar to this one (http://www.goodluckbuy.com/serial-bluetooth-rf-transceiver-module-r...) to my APM1.
It works quite well at normal bluetooth range of course. Ideal for tuning instead of using the USB.
The idea is to use this bluetooth interface while waiting for my 3DR telemetry set.
Moreover I use this app on my android which allows me to change PID and monitor my APM1. (http://code.google.com/p/copter-gcs/wiki/GUI)
Nice when you are out in the field and you want to change some settings.
Bluetooth examble don't have to use the iphone connector can go to a battery.
I have two of these boards but I can't get them to connect. How are yours wired?
Being a complete novice related to APM, I would be very grateful if you could show exactly how you hooked your Bluetooth module up to the APM1. I've got an Ardupilot 2.6...(is that the same thing?) and a JY-MCU Bluetooth Wireless Serial Port Module
I only really need to be able to use the Droidplanner or the Android app that you mentioned, to tweak at close range for the time being, so as to obviate the USB cable connection.
