generic wireless UART with OLRS pair

[Alexinparis]

Hi,

As quoted here:
viewtopic.php?f=6&t=3945&p=40325#p40325

Here is some simple code to build a transparent wireless UART with 2 OLRS compatible modules.
- guaranteed 20ms delay
- air speed: 57600 (same as OLRS => same expected range)
- UART interface: 115200 with a buffer of 256 bytes

By default, the link is symmetrical => it's the same code to inject on both RX&TX.
It's however possible to make it asymmetrical with #define settings

The achieved data rate is enough to support for instance MultiWii GUI. (the only test I made so far)
But this solution can of course be used for many other projects.

Nice Alex, good job.

I´m in for some stuff I would like to keep developing.

What is the expected range for those devices?

With stock antennas and max power, I would say something like 1km in direct view.
With specific antennas, probably several km.
