Remote Control Interface v.1.1

[KF5WGB]

Howdy OM's,
I help coding for a program called POTA Watch by W4ELP, Groups.io/g/W4ELP, to work with Log4OM (latest version). So far it works with HRD and N3FJP's ACLog. Since I use Log4OM, I want to add it to the program. Ed, W4ELP, is on board.
So far I got the QSO Adif managed to send via UDP and it is getting logged, <CALLSIGN>KF5WGB send to the callsign field works and updates. Now my problem

As per The Remote Control Interface document I send to port 2241:

<RemoteControlRequest>
<MessageId>C0FC027F-D09E-49F5-9CA6-33A11E05A053</MessageId>
<RemoteControlMessage>SetTxFrequeny</RemoteControlMessage>
<Frequency>14075000</Frequency >
</RemoteControlRequest>

but the frequency does not change. Same for Mode change. All I need is Freq and Mode change. What do I miss?
Since the QSO works fine, I think my code sending via UDP should be OK.

Thanks for any advice,
73,
Ralf

Ciao Ralf, we're closing the release but i'm checking that issue right now...

Is there anything on program log? like "is not a valid RemoteControlMessage"?
just to start from the beginning?

[IW3HMH]

message contains: SetTxFrequeny
Right message is: SetTxFrequency

Ciao Daniele,
Gracie mille, that fixed the Frequency change problem. I copied and pasted the XML from the Log4OM 2 Remote Control interface v.1.1 document. There is a typo in the documentation. That typo is also in the SetRxFrequency section of the document.

I still can not change the Mode. Here is what I copied from the documentation:
<RemoteControlRequest>
<MessageId>C0FC027F-D09E-49F5-9CA6-33A11E05A053</MessageId>
<RemoteControlMessage>SetMode</RemoteControlMessage>
<Mode>USB</Mode>
</RemoteControlRequest>

No error in the log file.

I also tried this to get the Radio Status:
<RemoteControlRequest>
<MessageId>C0FC027F-D09E-49F5-9CA6-33A11E05A053</MessageId>
<RemoteControlMessage>GetRadioStatus</RemoteControlMessage>
</RemoteControlRequest>

and the log shows:

Thanks for your fast response and help. Buona giornata.

Hi everybody,
I wonder if nobody else ever used the Remote Control over port 2241. If someone used it to change the Mode successful, please let me know what you sent. I also tried different port #s all up to 2299, no success.
Here is what I send, one time with the \n and \r\n and one time without. I do not know if that makes any difference. Anyway, there are no errors in the log file and the Mode does not change.

Code: Select all

<RemoteControlRequest>\n<RemoteControlMessage>SetMode</RemoteControlMessage>\r\n<Mode>USB</Mode>\r\n</RemoteControlRequest>

I also used the GetRadioStatus and my XML request just creates a ton off error messages in the log. Anyone was successful?
I copied both commands from the Log4OM 2 Remote Control interface v.1.1 Documentation.
Thanks to Daniele, the Frequency change problem is solved. I copied a typo from the documents.
Appreciate any advice.

Nobody? Not a single one is using the Log4OM 2 Remote Control interface v.1.?

If somebody could tell me how to change the Frequency, I would really appreciate it.
