Barry,
Glad that you asked. I suspect that you have been involved with the developers of the app during beta testing (wish that I had been). While I have never done real-time programming, I have programmed in Fortran, C++, and visual basic, not as a programmer per se, but for the purpose of doing engineering analysis. Okay, with that as I background, I would suggest the following programming logic:
1.) During the upgrade download process, I would have provided a message that states the required firmware for the app.
2.) Then, I would have programmed the upgraded app to check the currently installed WIU firmware version (this is available in the LuCI so it should also be available to the app, right?)
3.) Next, I would have the s/w check to see if the firmware meets the requirements. If not, I would post an error message at this point. Otherwise, after someone enters all of the information for a lash up, I would post the error message at this point (you need to upgrade to version 1.1 or higher) rather than stating that the command failed.
Does the above seem reasonable and implementable?
BTW, my WIU had version 1.1, but I reinstalled it and will check tomorrow to see if this fixes the lash up problem.
Thanks for what you do on the forum,
Tom
