Cosmo Communicator - Linux / Login required and encryption in Termux
« on: March 08, 2020, 07:16:07 pm »
Hey. This isn't really answering your question. But you could turn on device encryption and lock the device with a PIN? Then if you lose it or it is stolen, nobody could get into it? Another option if you're open to using other apps for SSH is an app called Admin Hands. It has a password function. So you can make it ask for a password each time you open the app. Actually I quite like Admin Hands. IT has a couple of nice features like being able to connect and run SSH scripts easily. It also has a monitoring function (which I assume just connects via SSH and runs top) but it's a nice way to quickly check your server resources.

Hope these suggestions help.

Cosmo Communicator - General Discussion / Poor battery life
« on: March 08, 2020, 07:05:21 pm »
Ah man - that sucks. I really don't understand how many people can have similar issues but others don't. Maybe a bad batch or something? I'm so glad mine doesn't have any of these issues that stop me from using it as a daily driver... But I'm frustrated for you. It's an expensive door stop! The sad thing is - if you have one that works it really is a most amazing machine. I hope you find joy with Linux - or if not, maybe pester PC until they agree to fix it or swap it out.

Good luck!

Yeah, the recently announced update sounds good. It has my hopes especially in regards to battery life.

Some of the problems I have on a regular basis: The status LEDs activate randomly. Maybe it means something, idk. Often they don't turn off when closing the lid, which is especially annoying when I was playing media before closing. It never stops blinking. After opening the lid the display turns on and sometimes just when I want to unlock it it turns off again. All I can do is close and open again, hoping it works this time. Two times I had to reboot in this state. About once a day it reboots on its own. Usually while I'm not using it. Sometimes while typing. It seems to be random. Since my SIM card is locked I'm offline until I notice it. Sometimes it doesn't turn back on on its own, sometimes it does. Sometimes the display stays black after the reboot. Then all I can do is enter recovery mode and reboot. Keyboard backlight doesn't turn off when it's not used. Sometimes the setting changes to off when the device is closed for a while. The CoDi update app notifies about its background activity all the time. I have to delete the notification almost every time I open it. Sometimes it does actually find a new CoDi version. Even when there is none. Camera quality is very bad. I stopped using it. Maybe in the summer it will be of more use when there is more sunlight. All Cosmo settings are reset to default on every reboot. Some apps are only usable in portrait mode. Autorotate doesn't work though. Sometimes it rotates for no apparent reason. Then I have to force rotate which rotates it back to landscape instead of portrait as usual. This sometimes crashes the app I was currently using, sometimes not. Bluetooth turns off when I'm not using it for a few days, WiFi can't be turned off at all. Do not disturb doesn't turn off after the set time. Sometimes while do not disturb is on incoming calls ring for about a third second then become silent. Battery usage data is not available. I lost all files on my SD card once and have no idea why. Scrolling background pictures are incredibly complicated to set up. I once brought it into a state where it rotated the screen at a rate of more than 1 Hz because I chose a file with the wrong dimensions apparently. I managed to change the background back after two days. Sometimes while charging the device unlocks without being touched. And so on. Probably all of this can be fixed in software. I'm looking forward to it. But right now I'm saving up for a different device.


Dude - you have a faulty unit. I have none of those bugs except for the auto rotate (which you can fix with Tasker) and the battery usage not being available (which you can work around with an app). All  those other bugs do not happen on my Cosmo. I really think you should return it to PC for a warranty exchange. If I had all those issues I'd be really frustrated too!

In the end, I bought a DisplayLink HDMI adaptor. They're not cheap, but they work 100% of the time. Essentially they have a little display chip in them. Again - nothing spectacular. Just 1080p, but if reliability is what you need for video out ,  are your only option.

Could you please care to quote which make and model? Mr eBay shows all with USB A connector and not USB C

Mine is a USB-3 type A conector. I have to use a little USB-A to USB-C adaptor.

You obviously did not perform the recommended goat sacrifice . But seriously, I've found it very hit and miss and I can't determine why it will work on some instances and not others.

Gemini PDA - Linux / Can I access the Debian fs offline?
« on: February 19, 2020, 05:23:08 pm »
Thanks Adam. You're 100% correct. Knowing my unfamiliarity with Linux and my tendency to experiment, I think I need to install rooted Android or something on another partition! I actually loaded up the flash tool, but I can't seem to work out how to backup up the Linux partition.

Is it possible to parallel install a second OS without messing with the Debian install? If so, what procedure do I follow? I assume I would need to partition the drive (I believe it only currently has a single partition with Debian as the only OS). Then somehow tell the boot loader that there are now 2 partitions with 2 operating systems (I assume I can do this by downloading a new scatter file from http://support.planetcom.co.uk/partitionTool.html)?

Gemini PDA - Linux / Can I access the Debian fs offline?
« on: February 18, 2020, 06:34:58 pm »
Thanks Adam. Seems like I have made a lot of work for myself! Question - Can I use the Flash tool to back the current Linux up to an img, then extract the file I need, edit it and pop it back in the image, then flash it back? I have no idea if that is possible or not...

24
I think this is a bit of a bug. However, the light does turn off when you close the Cosmo.

25
I think that is an excellent write up and pretty much mirrors my experience. The only app that I might add that I find "essential" to make up for a few of the shortcomings of Android / the Cosmo is Tasker. I have used it to automatically switch to portrait when I rotate my phone (good for those pesky websites and apps that hate landscape!), also to change DPI for apps that work better on a "tablet" and then back for other apps with teeny tiny fonts, and lastly to silence the phone when I am at certain places at certain times (eg at home on Tuesdays and Thursdays between 12 and 2 when my bub is asleep). But Tasker has a bit of a learning curve - so it isn't for everyone.

Good pointer about the Firefox plugins. I have to try them!

Gemini PDA - Linux / Can I access the Debian fs offline?
« on: February 17, 2020, 07:01:27 pm »
Hi all, I'm a semi Linux noob so I hope this question isn't too silly!

I have managed to stop my Gemini from booting into Linux by adding a line to /etc/fstab which apparently it doesn't like. Now it is stuck on the "Gemian booting" screen. I assume it is trying to mount the webdav addressee I added to /etc/fstab and it is getting stuck because WiFi isn't connected yet (or I just forked up with the syntax...).

Either way, I need to delete that line from /etc/fstab. I'm not dual booting - Debian in the only OS on there. So I can't boot into another OS and edit it from there. Can anyone help me with a suggestion of how I can access the file system so I can delete the offending line? Or is there a way to boot without loading /etc/fstab?

Thanks in advance for any hints and advice.

Cosmo Communicator - General Discussion / Compass calibration
« on: February 16, 2020, 06:18:40 pm »
I had to rack my brain - but here is where I read about the compass being disabled on the Gemini: https://support.planetcom.co.uk/index.php/Troubleshooting:

"Despite the compass sensor being present on the unit, the compass functionality has been removed from the firmware because of interference with the magnets used to keep the unit closed and make the device altogether thinner by pressing the keys down."

It seems like the compass has been enabled on the Cosmo, but could the strange results be due to this same issue? Strangely enough last time I tested my Cosmo compass was in the countryside a couple of weeks ago. The app said "Compass accuracy low" but it was actually working OK. I compared it to my other Android phone and both were showing all directions accurately. Now, I'm back in the city and the compass is all but useless - even after calibrating like Daniel suggested. It won't even point north correctly.

I have very little knowledge and experiences with compasses and magnetic fields, but is it possible that the magnets on the Gemini and Cosmo are quite strong, thus make it difficult for the device to find magnetic north? In the Gemini, they decided to simply disable the compass. But could it be possible that in the Cosmo, they adjusted the compass calibration to compensate for the magnets? Thus it is able to detect magnetic north, but the field is very weak due to the magnets.

I have no idea how if this is right, but if I compare it to - say - audible noise and sound waves. Let's pretend the speakers of the device are constantly emitting a loud sound. This would cause the microphone to have trouble picking up the sounds of voices for voice recognition. So maybe they tweak the device to "filter out" the specific sound from the speakers. This would enable the device to more accurately interpret the voices it hears. But the sound is still there - saturating the airwaves. So it would be ok if the voice was the only other sound or if it was very loud. But if there were also lots of other sounds as well - like a noisy room - then the device would have a lot more trouble "hearing" the voice than a device that wasn't already making its own sound... I may not have explained that very well...

So comparing this to the compass: in my case in the country side - where there might not be a lot of other things giving off a magnetic field. Even though the "accuracy" was low (because the device has to compensate for it's own magnets) there was enough magnetic "silence" to be able to "hear" the earth's magnetic field and point accurately in every direction. However, back in the city, there is too much "noise".

Sorry for my obviously completely non-technical jargon and also if this guess is completely off and that's not haw magnetic fields work! But to me, if this is an accurate guess it would explain the compasses behaviour...

I might be wrong, but I think you are never going to get better than low accuracy. I think the magnets that hold the device together are strong enough that they interfere with the sensitivity of the compass. Having said that, I have tested the compass and mine is pretty spot on despite it complaining of low accuracy.

What about just disabling the Amoledison app. Should solve the problem and it is not useful anyways.

I may be wrong, but I believe that - since it is a system app - you can only disable it with root. Also I'm guessing that disabling it will stop the CoDi from working (this may or may not be an issue for you).

Also - I'm guessing again - but due to the way the CoDi operates it may be that this app needs to keep the device awake. So the best we might be able to hope for is that PC make a change in a future update that allows this app to be disabled by the system if you turn off the CoDi.

From the name of the process - AmoledisonThread - I'm guessing what others have already assumed. Form some reason the communication with the CoDi needs the device to stay awake. So I'm guessing that PC have set this process to keep the device awake and respawn if stopped. Even if the CoDi is switched off, the process stays running. Maybe in a future firmware update, PC will tweak it so that - if you turn off the CoDi - the process is killed. That would at least give more battery life to those who don't need CoDi on.
