Default Power FLARM question

Hi Turbo

You are right, as usual. Changing the baud-rate is possible using
AT commands when the module is not paired, but cannot be
done over BT connection. Setting up environment for these
settings in not easy, otherwise we would have asked people to
do their own settings. We will program these to operate on
19200b speed, since I suppose that faster speed does not really
give any advantages, other than downloading logger files.

This is tailored for use with our club gliders with LX RedBox
FLARM units and external displays, but it works nicely with any
other FLARM unit as well, as long as they use the standard
RJ45/12 cabling.

I have added into youtube videos or testing of the Bluetooth
module and IOIO extension board for radio disturbances.
Results were good, and tomorrow we will place the order for
PCBs and components. If someone wants one, it's final call.
