with DCD, I no longer have text in my tag


 

I just added the DCD function on Direwolf 1.7
Since then, when my beacon transmits, I only have the carrier, and I don't have the text of my beacon. Why ?
in Direwolf I put:
PTT GPIO 26

#DCD COM1 -DTR
 DCD GPIO 24
Is it correct ?
Thanks for your help.


 

Typically, the TNC won't activate PTT when the DCD indicates there is activity on the RF frequency.
DCD function is typically used with the radio SQL to determine if there is RF.

DCD questions:
1. Why do you feel you need the DCD line?
? ? The software control is typically better than using DCD pins.
2. What is connected to the other end of GPIO24?
? ? ?Many (if not most) radios have Carrier Detect lines that require the minus.
? ? ?Are you connecting to the CD pin on the data jack?
? ? ?This means you need to manipulate the SQL.

The DCD option in direwolf.conf is intended to light up an LED when the Direwolf TNC gets a valid HDLC signal.? It shouldn't have any impact on anything else.? If you put a "#" in front of this DCD line and restart Direwolf, does everything work as you expect??? When you start direwolf from the command line, what do you see from STDOUT when it starts?? Please paste that output into your reply email.

PS.? Direwolf v1.7 is still a pre-release and there might be other bugs.? Unless you have specific feature needs that are only available in v1.7, consider running v1.6 instead.
