Timout when sending key repeatedly

[TL_Bert]

I'm sending a volume key to a device in bursts of 25 times with 0.1 seconds between keys.
Between the bursts other various keys are sent at a much lower rate.

At random times this produces some sort of timeout in the server and the connection closes. I have to restart the server for it to work again.

I'm sending the keys from custom software in c++ using the irtrans library.
I'm using a LAN controller XL.

I set loglevel to debug and these are the last line

Code: Select all

Send [2] remname- vol- [10001 - B:0  M:0x1  LED: Default]
Time ACK Wait: 1.200000 ms[SEQ: 29]
Time ACK End : 12.300000 ms

LAN SEND - RESEND [50.200000 ms]
TimeoutSend Status 272 - 272 [1]
Network connection [2] closed

And this is from our programs logging file:

Code: Select all

ERROR.IRCONTROLLER.SEND_KEY: TL_IrController::SendKey Retry on Error:TimeoutTL_IrController::SendKey Fatal Error: Timeout

This is from the latest software version, but initially had the problem in a previous version as well.
Does anyone have any idea if we're doing something wrong?
Thanks in advance.

Edit:forgot to mention that I'm using Windows 8.1 64bit

Still have this problem. And I noticed it also happens randomly after a time of use, not only when sending keys rapidly.
I also noticed that, even though I get the timeout error every time, it still sends out the keys.

Switched to the USB irtrans and didn't have this problem but is obviously not a good solution.

Hi,

I suppose you are encountering some kind of buffer overflow. One IR Code can easily be around 200ms long. If you send bursts of 25 codes with 100ms intervals they are stored in a buffer until the IRTrans is ready to send a new code and at some point the buffer overflows.
This also might explain why you don't have this problem with the USB module: There the buffer can be the size of your RAM!

I suggest you slow down the repetition rate or you learn a long button press for this kind of command.

best regards,
Eric
