How to swap frequencies?

Recommended Posts

So I've got an Arduino running radios etc, but I can't get it to swap the frequencies.


I send the code from my arduino "swapc1"


Lua accepts this, but I can't get the following to work.


Sent from Arduino: swapc1:1

  char buffer [20];
  sprintf (buffer, "%s:%d\n", name, value);
//  lcd2.setCursor(0,3);
//  lcd2.print("S:");
//  lcd2.print(buffer);
  Serial.write (buffer);

Lua Script

    if string.match (str,"swapc1:(%x)") then

I did have a script trying to manually swap them as well, but would rather use the presets.


Anyone able to assist?

'swapc1' would suggest you're trying to swap the COM1 radio, but 66444 does COM2. Have you tried 66372 (COM_STBY_RADIO_SWAP)?


Another method you could try to swap radios is writing the following byte values to offset 0x3123:


8: COM1 swap
4: COM2 swap
2: NAV1 swap
1: NAV2 swap
