If you have been following this project you will have seen in PCB 2.1 I added support for UART telemetry radio directly on the board here: 

Located here: 

This allows for a long range telemetry radio (for ResQ Air Drone use) but ALSO allows us to easily add a Bluetooth radio which you can use to see the information live from your phone/tablet. 

This is intended to be used when ResQ is utilized from a light aircraft or helicopter- you can mount the ResQ ground unit (or air module) OUTSIDE the aircraft fuselage and wirelessly get the data/targets right on your phone.  Handy eh! No running wires or messing around with the aircraft structure- just jump in any Cessna- attach ResQ to the wing strut or wherever- point it downward  and go search :)

Lat night I updated the code and live tested an HC05 with the ResQ 2.1 PCB system

After some learning to AT command program - Sure enough it works great!  It happily yaps out all the data over Bluetooth no problem:

Sometime downrange I will try to make an APP which will graphically display the data on a map- should be easy as I am already providing GPS Lat/Long and the target info. Just need to plot it to make it nice and friendly to human eyes. For now though- it can work- it shows you when a target is detected and where in text form. 

I've added all the instructions to my user and assembly manual (FYI ALWAYS update your manuals RIGHT when you finish a task- otherwise it is very hard to go back and get motivated to write documentation). It will be published here soon once I clean it up and make it really good for people to make this project.  Snippet:

Since AT programming the module via a serial programmer (needs to have baud rate changed to match ResQ)  isn't the easiest thing- I went ahead and made these available pre-programmed alongside the ResQ kits on my website http://store.mkme.org/product-category/custom/

They are even programmed as ResQ name and PIN is easy at 1234

Next update here should be a HUGE one as soon as I finish it :)
