PGenerator / wireless connection
Thanks, all! I finally got this working, just by poking around.
Problem was that on the Device Control page where the "Available Wireless SSID" is shown, I had to select my desired network SSID from a drop-down box, even though the box already contained the correct SSID! Then the "Connect" function worked! What a head-scratcher that was!
I have now used both wifi methods (AP and Client) and wired, still need to spend some time trying to get the Bluetooth path working. I've found Bluetooth pretty flaky in the past, but I can see the advantage...although as long as I'm in my own home, wifi is probably my method of choice.
My main TV is the LG C9 OLED with iTPG, so I don't need the PGenerator for that, but should come in handy for my other TVs. Have used Mobile Forge via AppleTV in the past, but had a couple of RPis lying around doing nothing!
