ReceiveIR not working for the first IR comand after pause

[alexirion]

Hello!

I'm using the IRTrans C shared libray in my home automation software to access IRTrans. (The ethernet version was used.)

I use the function ReceiveIR(socket) in a loop to receive IR comands. At startup time I once call ConnectIRTransServer(socket) for initialization.

Everything then works fine, but when the first IR comand comes in after a long while with no IR comand beeing send(> 2 hours), then the first comand is not received by ReceiveIR(), that means, it does not return. A second press of the IR remote then leads to the correct result and subsequent calls are also working fine until again, a long pause with no IR signals happen. Then the first press is ignored again.

For the first press, to "wake-up" the system it does not matter which IR comand it is, a command not in the database also works.

I found the following workaround for this issue:

In the loop I connect to the server, wait with a pselect and a timeout of some seconds on the socket, call ReceiverIR() or when the time out happened close the connection to the server by DisconnectIRTransServer() and open the connection again.

So, with repeative opening and closing the connection, the issue of the first IR comand beeing ignored is gone.

Now, my question is, how this behaviour can be explained and if there might be a proper solution?

Hi,
so far we do not know this problem.

Does the irserver show the IR Codes in "Detected IR Commands" ?

Hello,

I'm running under ubuntu server. I now set the options -loglevel 4 -debug_code -timestamp to get the ir comands logged by the server. I let you know about the logs, when I reproduced the problem.

Hello!

now, I reproduced the issue and added the server logs - see at the end. Apparently adding it as attachment resulted in the error message: This file extension is not allowed.

At 16:42:32 I pressed the remote for sending the comand shutterrearup from remote groundcontrol.
The logs show, that this comand was not received by the server - instead there is the following line:

2010-11-07 16:42:32.724 IRTRans LAN IRSend ACK: 230

What does this mean?

At 16:42:34 I send the comand rolloup from remote groundcontrol - it was succefully detected by the server.

The same for the following comand shutterrearup from remote groundcontrol.
