Channel changing using uutx USB-UIRT and STB

[lchiu7]

Making progress on changing the channels on my STB using a USB-UIRT and uutx.exe to send the IR codes.

I can send the codes fine from the command line and the channel changes. That works fine for single digit channels. But for more than one digit I have to have several uutx commands in the bat file, one for each digit. That also works okay.
However if I use that same bat file in this option in Nextpvr it doesn't seem to execute the bat file at all. I know that it's invoking that part of the code since if I have uutx.exe as the exe and the hex string for the code to send as the argument that works okay. But I need to send more than one code and a bat file seems to be the only way. nrecord.log indicates that it tried to execute the bat file

<tuning>
<type>HDPVR</type>
<locator>
<channel>18</channel>
<input>1</input>
<audio_input>RCA Front</audio_input>
<blaster_executable>C:\Apps\xmlTVNZ\18.bat</blaster_executable>
<blaster_args>{channel}</blaster_args>
</locator>
</tuning>

but there is no error nor is uutx executed.

Have I missed something here?

The commands with codes work - the bat file does not

you'll have to run cmd.exe /c before the batch file for it to work...
when in dialog to select .exe, type %comspec% in the box and it will magically change into your machine's cmd.exe w path...
then in arguments, put " /c blaster.bat {channel}"
that way, cmd.exe /c executes the batch file, and exits...
of course edit the blaster.bat to whatever your batch file is named..

Thanks for that. That is certainly more elegant and flexible than my solution which was to find a program to turn a bat file into a self-contained exe! That works but is somewhat OTT
