I did that some time ago, but maybe a later config file left that off.Â*
Thanks for the pointer.

There is a Mode S filter if you set it in flarmcfg.txt.

# transponder type (0=None, 1=Mode C, 2=Mode S)
$PFLAC,S,XPDR,2

Confirm your ICAO address in the Mode S transponder and FLARM ID ($PFLAC,S,ID,XXXXXX) are the same.

They continue to work to minimize false alerts, so keeping firmware updated is advised.
