generic serial plugin not configured when girder starts

[codyzu]

When girder 5.0.0 build 523 starts the serial port does not appear to send commands. To get it to work I have to:


Goto settings->plugins->serial tab
Click on Com 3
Click on Change Device
Select any device other than the one I'm using
Select the device I'm using
Click OK Change


It works perfectly after performing the above procedure. I added some debug messages to my custom serial device lua file that is included in the bottom of the post.

Here is my lua console log from when girder starts to when I have it working. I've highlighted where I do the above procedure:

end
Super.ReceiveResponse(self, data, code) -- must call the parent's ReceiveResponse
end,

})

serial.AddDevice(device)


Not sure if this is unique to girder 5. I just started using the serial plugin after I installed girder 5.

[Ron]

Are you using the Generic X10 Remote plugin?

[codyzu]

Yes, I use the Generic X10 plugin for my Firefly remote. Also, I left out that I use the serial plugin to control my LG TV and that I use a USB to serial adapter to provide a serial port. As you can see from the lua console log, when serial communication is working, the TV echos the serial characters back to girder, hence the extra recieve messages before the commands are acknowledged. Thanks!

[Ron]

Give this modified plugin a try. It grabs the comports before the X10 object can and then releases them ASAP before lua starts-up and thus blocks the generic transport plugin ( e.g. serial comms.)

[codyzu]

It works! Thank you!

Is this an issue that will be resolved in a future release? Or should make sure that I hold on to that file when upgrading Girder versions?

I just found another reason why I love Girder...super fast support!

[Ron]

Unless issues come up with this work-around this file will be in every future release. However you might want to hang on to the file just to be sure.
