Haven’t had a chance to try on Crimson, but I know Byzantium does not have the needed package versions for it to work.

Interesting. I seem to have it. Starts up fine, although I don’t have any idea if it otherwise works as I don’t have any visual voice mail to test it with. Are you using byz backports or no? Anyway, this seems like a question that should be in that thread.

That was quite the tip, thank you.

It seems we have gotten a new update news posted (January). Nice to see progress and steady communications:
No new image to test (as of yet), though.

Just copy to /etc/firmware/brcm/ the next files:
BCM4362A2.hcd
brcmfmac43752-sdio.bin
brcmfmac43752-sdio.clm_blob
brcmfmac43752-sdio.txt
The files from LibreELEC looks like the right choice, other links work not so stable for me.

I will create a .bak of the originals before attempting this. Maybe it will be good and I won’t have to remove that status.

So SparkLan BT should be a bit more stable with it then? I always had issues with the SparkLan module dropping bluetooth connection to smartwatches. Also was a pain to pair to any vehicle as well.

It is difficult to say… The difference is not so big, but my personal opinion that LibreELEC a little bit stable (at least to listen music by BT headphones). So, it would be interesting to get your feedback 
It should be noted that there is no official FW upgrade neither from Purism or SparkLan…

Partly why I started a thread for third party Wifi/Bluetooth modules and WWAN modules.

I got disk usage 80% after flash crimson, is this normal? Thanks,

You mean, when you flashed, your system only uses about 80% of eMMC disc space and the root/home partition doesn’t fill the whole disc (showing available root/home disc space as just few GB)? Yes, normal. Installation is not optimized yet to automatically fill the whole disc. If you want, I think you can use external computer and in jumpdrivemode use Gparted to grow the partition to fill the whole disc. (caveat: it’s been a few months and I’m working on memory here).

You can use GNOME Disks instead:

That issue #19 on sound output and mic input has been closed recently. Could someone confirm that it is now possible to make and receive calls in Crimson? Is the new build with the fix already available? If calls and SMS are working, I would be interested to join testing Crimson.
Should be fixed now with librem5-base-defaults 67pureos1.

I’ve tested bluez 5.79 for a couple of weeks and it works really good (on Byzantium, but Crimson backports also contain that). I observed only some delay of about 5 seconds to BT button becomes available after the phone wakeup, but headphones connect from the first try all time.
Note: librem5-base should be upgraded first as far as it contained one conflicting file.

It looks like Crimson work is progressing a lot lately so I’m hoping to try a Crimson alpha + your backports with this soon.
For now, I’m leaving my franken-Byzantium alone

Just worried about that when the Crimson is out in any luck this year, a lot of packages will be already in the middle of the life cycle. Some of the applications are really old such Phosh .34. Is Crimson based on the Bookworm? if it is, I think it is good before 2028?

backports forever!

It looks like that version is deployed now in crimson-updates. Has anyone received that update? If yes, do calls work for you?

I went back from pmos to pureos again without back ports. Now a lot of apps are gnome platform48, super slow on frame rate somehow. The eog image viewer can’t even be used. Gtk3 is still the fastest and smoothest so far, but I don’t if Purism let librem 5 support gtk4 it is going to be the same optimaization. The phosh 0.32.0 is also laggy as hell.
I think by next year, maybe a new model will be out:D
