Duet can't find players

[paulster]

There is a bug where if the Controller firmware gets too far ahead of the Receiver firmware it won't then see the old Receiver at all, so you may have fallen foul of this.

I've reported this bug and Ben started to look at it, and then left Logitech. I'm not sure anyone has ever bothered picking up the ball since, but that's kind of par for the course with the Duet.

Think I may have this issue as well. Is there any way to get out of this situation? Can the Receiver be forced to update its firmware with a certain version or file?

Easiest way (if you don't want to downgrade your entire SBS installation) is to download an earlier firmware for the Controller and load via an SD card so you force the Controller back to an earlier firmware that can talk to the Receiver.

When you restart the Controller it'll try to upgrade but press and hold the left button to keep it on the old firmware. Then you can set up the Receiver and let it upgrade itself again.

I discovered this when a friend bought a bunch of Duets that shipped with old factory firmware on them. First thing that happened was the first Controller I configured updated itself (a good thing, you'd think) and then I was unable to set up any of the Receivers until I finally twigged to use one of the other Controllers and force it to keep its old firmware.

Ben was starting to work on this because it's unacceptable behaviour and effectively bricks any Receiver that's been left switched off for some time, but that was right before he left. I don't think anyone's picked it up since.

Ok - Thanks for that. I didn't realise that you could plug an SD card into a controller but will have look tonight.

I've now tried that. Downgraded the Controller's firmware to 7.5.1. But still can't connect to the Receiver.

Same circumstances as before - the Receiver appears on the Select Player screen on the Controller, select it, select Ethernet connection, and then tries in vain to connect to the Receiver. In the meantime the Receiver goes from red flashing to Green (IP address?), and then to blue. And then never seen again untl I do another factory reset.

On the Controller, under Diagnostics, everything is ok excepot that it hasn't found the Server. Why would that be?

The thing that really annoys me is that I had 7.7.0 going successfully - worked great for one listening session. And nothing since.

I have spent so many hours sorting out problems with the Duet. I was thinking of buying a Touch as well (for its 24/96 capability) but I think I will now look at other options. A consumer electronics products shouldn't be this hard!!

Ah, that's the DHCP bug I've raised and no-one has bothered to look at (see the bug list in my signature).

I've raised it with Logitech support directly and they've told me they have no access to the developers. I've sent a PM to Felix but he hasn't responded so I'm guessing he's left.

This is really crap. They've introduced this problem recently and just buried their heads in the sand.

Appreciate your help to date Paulster.

Is there a work around for the DHCP issue? If I go to fixed IP addresses for the Controller and Receiver - will that work?

[paulster]

Just factory reset it once or twice and it eventually connects. You can press and hold the left button on the Controller to bring up the Choose Player menu to configure it. Then don't power it off!

It's a real pain.

But that's the problem I have. I get the Choose Player option, and if I reset the Receiver then the player appears as an option. But when I select it, the Controller just tries to connect to the player - but never achieves successful connection.

I've gone this route since 2007/2008 .

All players and controller have fixed ip (not dhcp reservation in router ) and my desktop to, the only dhcp things I have is my iPad and the work laptop and friends and guest stuff .
