Bluethooth Range
Hey Guys,
Whats your Bluethooth Range? HC05 has a pretty bad range so here is an idea.
To keep the Tracker Compact, we might use a class 1 bluethooth module. That will get us 100+ meters range: https://www.sparkfun.com/products/12580
The bad thing is, that most smartphones dont support class 1 except the iPhone 7 i think.
So, maybe its possible to write an Chrome App, or standalone App for a Laptop and use this Class 1 Bluethooth Adapter.

A friend also tested various wifi modules like ESP... he only got 10 meters and had TCP/IP packages losts
...or..
is there any "Android App" Emulator which accepts bluethooth connectivity? So we can emulate the App on WIN/MAC
I have an other idea for increasing the range dramatically without loosing the bluethooth feature. Lets build a master slave class 1 bluethooth gateway. Should work: https://learn.sparkfun.com/tutorials/using-the-bluesmirf/all
Each of these modules has a Bluetooth transceiver on it, meaning they’re capable of both sending and receiving data. They’re perfect for directly replacing a wired asynchronous serial interface. Free of wires, your devices can be up to 100 meters away from each other. On top of those benefits, these modules are also very easy to use. There’s no messing with Bluetooth protocols or the stack, just send data over a serial interface, and it’s piped through to whatever Bluetooth module to which it’s connected.
In this tutorial we’ll cover everything you need to know about these Bluetooth modules. We’ll begin with an overview of the hardware, and the differences between each device. Then we’ll get into hardware hookup and example Arduino code.
I find it makes a big difference if you can elevate the bluetooth module above the ground. I use CAT5 cable to extend mine out and away from the Chorus box. I can get around 50m away from it and still have communication that way. Its elevated maybe 1.5 meters off the ground.
Thanks for your contribution. 50m with Cat5 is awesome. i should try that. If it works stable, the above solution is overkill, indeed! =)
My CAT5 cable is only about 4 meters long. Then I just mount it on a stick to elevate it :) Very low tech solution, but it works for me!
I just bought this as a range enxtender =)

I hang my timer from a tree branch and easily reach 20m to where we sit. I'm sure it would go further.
