API Help

K1ESE Member ✭✭✭
edited May 2020 in SmartSDR API
I want to access the API to turn a relay output off and on.

This works -

ampline$ = "tx1"
        handle = TCPOpen(radioaddress$, 4992)
        temp =TCPPrint(handle, "C0|interlock "; ampline$; "_enabled=f")

It turns off.

This doesn't -

ampline$ = "tx1"
        handle = TCPOpen(radioaddress$, 4992)
        temp =TCPPrint(handle, "C0|interlock "; ampline$; "_enabled=f")

It doesn't turn back on.

Please, what did I mess up?

    Did you mean to say "_enabled=t" (true) in the second snippet?

    Not an expert on the FlexAPI but your two sample code fragments, as written here are identical. If that's what you really have, then I suspect you need to change "_enabled=f" to "_enabled=t".

    Yes, I copied wrong from the program.  

    This doesn't work -
      temp =TCPPrint(handle, "C3|interlock "; ampline$; "_enabled=t")

    I'm guessing I have messed up the syntax somehow.

    Do you issue commands C1 and C2 before issuing the C3 that doesn't work? There may be something going wrong in the intermediate code that you've not shown. Do you close the TCP/IP connection after each command?

    As long as you asked...

    Liberty Basic Code -

        bmpbutton #main.start,"C:Tune Antenna Tuner SafelyTune.bmp",[startClick], UL, 0,  0
        'button #main.reconn, "    RESET    ", [reconnClick], UL, 0, 76 , 184, 30
        '-----End GUI objects code

    open "TS" for window as #main
        'print #main.reconn, "!font ms_sans_serif 14 bold"

        print #main, "trapclose [quit]"

        'read .ini file for address, RCA TX line, tune power

    Is the issue that you used a capital "T" instead of lower case "t"? 73, Len, KD0RC
