Another correction: I get noise on the headphone output if and only if a charger is connected to the RHS (or bottom in portrait mode) USB connector (and powered). Just connect the charger to the other (LHS/top) USB connector of the Astro Slide to get rid of the noise.

Ah, so *that's* why I couldn't repeat the issue. Not that I use 3,5mm jack very often - but I have used the top/left usb port for charging.

Cosmo Communicator - General Discussion / Re: Planet's service times
« on: January 26, 2023, 12:30:43 pm »
To let others know, I contacted Planet.

1) The cost to replace a battery is 125 GBP + shipping (to both directions), and they promised service time of four days. They claim it's "forbidden" to send batteries (I'm not sure what to think of that).
2) Cost to replace CoDI is also 125 GBP, or just 95 GBP for the part
3) Time is 4 business days for battery, 3 business days for CoDI.
4) "Batteries are new and covered for a minimum of 6 Months"

I seriously have to consider whether to spend near 300 EUR to get Cosmo fixed and with a battery in better condition. I mean, I think I would enjoy it as a Linux-based micro-laptop, but the price point is just a tad too expensive, especially considering I paid about 500 EUR for the whole thing 3 years ago...

Astro Slide - Android / Re: Fingerprint issue
« on: January 23, 2023, 02:55:49 pm »
For me, the fingerprint sensor has been working after I learned the (stupid) quirk:

The FP sensor is active *all* the time, even when screen is locked.

So I used to do:
 - Press the lock button more or less incorrectly, or with a different finger that I have programmed, or whatever => result: The FP reader tries to read my finger several times, fails, and locks.

What I do now:
 - Program the fingers that I use for unlocking, and instead of *pressing* the button, I just rest my finger (usually thumb, when holding the phone upright, or middle finger, if sliding out the keyboard). The phone unlocks (the screen goes from completely black to an unlocked phone).

In addition, I've also turned off the "lift to wake" option.

Cosmo Communicator - General Discussion / Planet's service times
« on: January 16, 2023, 03:26:44 am »
Hi,

  now that I've gotten my Astro shakedown cruise completed, I've been thinking about installing Linux for the Cosmo. However, my Cosmo has very bad battery and I'd like to get it replaced. Apparently Planet still has a few SXX600's around. I also have a broken CoDI - maybe get that fixed as well.

  Does anyone have any experiences in how long does Planet take to complete service if I ship this over to them?

  The cost is probably a quite high so if it's going to be a hassle to do business I think I'll just forget about it...

Astro Slide - General Discussion / Second impressions
« on: January 13, 2023, 06:12:36 pm »
Continuation from https://www.oesf.org/forum/index.php?topic=36856.0 now that i put Astro through a major test - 3 week trip to New Zealand. I am typing this on Qantas flight from Sydney with their inflight wifi - on Astro.

Summary: I love the darn thing. Worked with Optus (AU), Spark (NZ) and some provider in Singapore as well. No issues with wifi either.
Location works, even in car and offline - most of the time. Ironically the only place where GPS fix would not be reliable was Queenstown... but then again, it is basically built in a valley. Worked quite nicely even inside a boat in Doubtful sound.

Issues are minor, but ran into a few:

- Sometimes the device would not accept input from touch screen, and I had to reboot. It looks like some app is "overlaying" everything, including lock screen. Not sure how to repeat this.
- Android auto would sometimes fail. I could get it to work by either rebooting or killing navigation app (Here wego or google maps, both in offline mode). I noticed that AA would only work on right side USB port. Not sure if this was due to the rental car (Mitsubishi ASX, year 2020) or Astro
- USB charging did not work on planes. The usb port on the seat seemed to shut down both on Qantas A330 and Finnair A350. (Maybe fast charging negotiation?). Did not try on Qantas 737. OTOH, battery lasts a long time.

Anyway, I only hope that Planet would deliver the protection packs and gets those software updates going, but I love the hardware!

Astro Slide - General Discussion / Re: Belt cases for Astro?
« on: December 21, 2022, 04:31:15 pm »
Now that it's been a while... The case I bought has been working with my Astro quite well. It's a thick device, so it's a *very* tight fit, but since leather stretches just a bit, now after using it for a week it's actually quite usable. However, if astro were just 1 mm wider, I don't think it would fit anymore...but I'm very happy with what I got!

Astro Slide - Hardware / Re: Fast charging
« on: December 21, 2022, 04:14:18 am »
I'm just using Planet's provided charger and cable, nothing fancy.

With Cosmo's charger, I also got lower results in the 8W range.

Although, frankly, I'd *prefer* the very slowest, basic charging - that supposedly increases the lifetime of the battery. Unless I'm in a hurry, of course.  It seems that I get around 5W when I plug Astro to my laptop, but still around 9W when I plug the charger to the left port. So even the left port has *some* form of fast charging.

Astro Slide - Android / Re: Mobile connection flipping
« on: December 20, 2022, 10:29:45 am »
Does the phone stay registered if mobile data is turned off and only starts flipping after you try to activate mobile data? If yes, then changing the bearer-type to IPv4 might indeed help. I've had this happen with laptop's mobile data SIM (not with DT though).

Please check this when wifi is connected.

Nope. The services running are:

- Settings
- Bluetooth
- App Bar
- Google
- Missed notifications reminder (I installed that one)
- Planet Keyboard
- Quickstep
- Android Services Library.

Nothing else.

If I disconnect/reconnect wifi "Android system updates" runs for a second or two. No deejoy-dota.

Astro Slide - Android / Re: Planet Updater SSL Error
« on: December 18, 2022, 05:37:13 am »
As I mentioned in the other thread, the planet updater goes to https://pulsar.planetcom.co.uk/ (if you go with a browser, you can bypass cert check) and it's pretty much empty for now.

There are several firmware versions in the wild though, someone on IGG said that their security level is Nov 2021, mine is from Jan 2022. Really strange that they cannot even bring the older batches to the same batch as newer ones... And the whole deejoy-dota business.

I'm assuming it's Pump Express Plus, given the relative youth of the SoC and the presence of wireless charging; I have seen this described as PD compatible, but want to understand whether a PD charger (or even a PD compatible version of QC one) would fast charge an Astro.

I plugged my wife's Samsung charger to Astro, and got 9,5W at 55%. Astro's own charger still got 14W. So it's at least some partial compatibility.

Same applies to at least Microsoft Authenticator. Something odd with fingerprint service.

Astro Slide - Android / Astro's three (four?) system updaters
« on: December 15, 2022, 05:07:25 am »
I don't have the deejay-dota on my Astro that was mentioned in other thread, but I took at tcpdump out of my Wifi AP.

We have at least three system updaters in the system.

Under "About phone" we have Planet's updater. It talks to pulsar.planetcom.co.uk.443 (and fails with a cert error). You can go with a browser to https://pulsar.planetcom.co.uk yourself and get a text "Cosmo Communicator Update Site ". Maybe this is spillover from Cosmo/ CoDi updater?

Then, next to that, we have "System update". It talks to Digitime, app-fota.digitimetech.com. This reminds me of the problem with Cosmo. https://wuffs.org/blog/digitime-tech-fota-backdoors - not sure if I should be concerned.

Finally, under "system" we have yet another updater, that talks to android.googleapis.com and seems to have Google's look & feel to it.

I contacted Planet, let's see if they respond in any way about what's going on here..

Astro Slide - Hardware / Re: Fast charging
« on: December 15, 2022, 02:52:58 am »
My battery had drained to 80% overnight (from 90%). First note: Looks like Astro is *much* less power-consuming than Cosmo.

Anyway, when I now plug in charger, Wattz shows 8 to 9W charging rate (via right port).

I'll let the phone discharge a bit more and see what happens.

Update: At 70%, the charge speed is 12W.

Update #2: At 60%, the charge speed is 14W.

So looks like the rate increases when SoC goes down.

From 40% to full in 20 minutes? That's 60% of 4000 mAh battery, 2.4 Ah. Let's use the effective voltage of 3.7 V. That's 8.9 Wh of energy, transferred in 1/3 hour (20/60 minutes), this means the power arriving at the battery needs to be 8.9*3 = 27 W. The charger only claims to be able to deliver 18 W max. and there are losses in further conversion from 9 or 12 V down to the battery.

When 'full' means 80%, then we arrive at about 18 W being pumped into the battery … when the electronics in the Astro itself work with 98.7 % efficiency, this could be barely possible.

I installed the Wattz app from F-Droid to get a display of the power and current going into/out of the battery. Right now, at 65%, it only shows 3.1 W charging (matching what the USB power monitor device says, but also without this one in between). This should be much more. Strange. I wonder if there is some setting. Also: Wattz claims 2000 mAh at 65% … this does not look like 4000 mAh for a full charge.

It might have been misleading minutes. I just plugged the charger in and it said that time to charge is 20 minutes...I didn't actually clock it.

With Wattz, right now, I'm at 91% charge and it says that there's 11Wh (2,7Ah) of energy. If the battery is 4Ah then something is wrong here. Of course, it might be that some portion of the battery is not really used (like it's with EVs), but that's still quite a bit of different.

If I try charging, I get -4,6W.

I'll let it drain overnight and check what the figures are when SoC gets lower and charging is attempted.
