Today I have tested with two Up2Stream Mini v3’s.
I had ‘older’ firmware 4.6.xx26 (or close to it) on two Mini’s. I made the network install with them, and viewed both via 4Stream App.
Quite soon I got a pop-up, mentioning new firmware was available. But I discarded the message: do not upgrade.
Then I tried to combine the two Mini’s into one group for stereo. But I got a notification that it wasn’t possible, because the software version was outdated, and I should update it.
Then I tried to connect to one of the speakers, but it was impossible.
What I found out
- I wasn’t able to connect to one of the speakers, because it was in the process of upgrading the firmware. I did not expect that, because I discarded the request to install the new firmware. So maybe this means that 4Stream or the Mini’s initiate the firmware upgrade by themselves. I had no control over it.
- My attempt to combine the two Mini’s to a stereo set didn’t work, because at that moment they had different firmware versions. And it seems to me that two Mini’s can’t be combined when they have different firmware versions.
- I wanted to test with two Mini’s having older firmware, because I experience serious volume control issues with the latest firmware (4.6.328252). But since the Mini was upgrading itself, I had no control over firmware version, and could not execute my test.
- I am human, so I can be making wrong conclusions. But can anyone who knows about this comment?
