easy to rig up the following

voila, a simple test rig, just setup the parameters on the ERF and it will receive the ARF data

Lee, what would the serial commands be to set this up to receive PilotAware?

Just been reminded of this thread.

These are the settings you need to make for the config of the radio
in order to get into AT command mode, issue '+++', then wait for 'OK'

Code: [Select]

atch 3
atcn 7
atcs C8
atdr 2
atpk 18
atrt 10
atpl 8
then await command mode timeout, or issue 'atdn'

thanks Lee,
I have some progress, it no longer shows the text at cold boot from the PA and it does show text every 2 seconds, which i guess proves the PA box is working, however the text is not readable, should it be or is it encoded?

This is what I'm seeing:

Code: [Select]

$«P@zÑ? ÷RB          Ø$«P@Ñ?÷RB          “$«P@éÐ?÷RB          t$«P@Ñ?÷RB          š$«P@RÑ?÷RB
The AT commands respond with "OK", this is all a bit like the old days of programming the modems or fax modem!

Hi
The output is HEX probably non-printable characters. if you can configure your client to be binary, you would see a string
of 24 Hex bytes.

BTW, the '$' indicates the start of the packet

in hex it looks much better!
Now to decode it found the spec on your site, lets see how much C# i can remember!

thanks Lee
