I’ve just today received my order (#17336). Got almost everything put together and setup.
Went with the oowow-supplied 64bit Android 11 image.
I’ve already had to order a replacement gen2 dsi cable as the current cable trips the whole board. So I can only use the hdmi for output for now. Replacement is expected to take over a month to deliver (I’m not paying another express delivery charge for a $6 item - DHL even wanted another £100+ on top last time!).
5g modem works well. I did a speed test earlier; speeds weren’t exceptional, but that’s a network matter. It works well.
Camera doesn’t work at all. Plug it in and power on the board, and the board beeps constantly until powered off and camera removed. Then it boots fine again.
Overall: board works, 5g modem works, camera doesn’t, touch screen doesn’t. I’ve historically had nothing but good things to say about Khadas. I own a Vim3 Pro and an Edge 2 Pro, and they work perfectly. Disappointed this hasn’t completely worked out of the box. Hopefully the replacement gen2 cable will fix the touch screen issues. Not sure how to fix the camera issue.
thanks, @goenjoy. this was the case. however, it only led to more problems.
running the camera app forces the board to restart. every time. without fail. at which point, it gets stuck in a reboot loop for an indeterminate number of reboots. so i have to leave the camera disconnected, making it seem like wasted money.
reboots also happen with aptoide tv. this app doesn’t even load properly. i have to right click the mouse from within the app after it hangs for a bit just to display the menu, which then reboots the board again.
this may not be of any use to your cause, but this reboot loop is very common when your vim board is not being supplied enough power to power the additional things you attach to it. worth you checking this at very least
One of the biggest problems though is that there appears to be no Phone by Google app. Searching on the Play Store shows nothing. So despite having the working 5g module with an activated and working sim, it seems like I can’t make phone calls. Unless there’s a phone app already on this Android image that I’m simply missing - but I have searched.
as for the camera…im not sure as i have not used a camera with my vim4 yet. maybe just double check the connector is fully inserted as it can be a bit tricky sometimes. also check that all drivers/software is installed to support it if any. this is as far as my help can go, maybe a khadas representative will respond soon if your issues still persist
for the camera, i’m unsure too. it’s one of the khadas cameras from their store. so it should work.
as for the phone app, thank you for the alternative list. i managed to find phone by google in the aptoide store. but it fails to install. …actually, while i type this and enjoy a bit of lunch on my break, i think the play store app is what’s forcing aptoide not to install it. i’ll test it right now…
…play store blocks it. it thinks the android image is for a tablet image for which phone by google isn’t compatible. it gives a “this tablet isn’t compatible with this app.” error when i go onto my play store profile, and look at apps not installed - as in apps i’ve had before or currently have on other android devices.
i think i can solve this with google voice for workspace. it’s free for personal use.
noted on the pd side. i’ve wiped android because of the dialler issue - who’d have thought it would be so difficult to install a dialler app on android? - but the ubuntu image is not much better.
i’m a fan of linux anyway, so i’m quite a bit more comfortable in this environment. but the bundled support for the modem is very lacking. it doesn’t even list 5g as an option in mobile settings, and in fact won’t let any option other than “2g, 3g, 4g” be selected without complaining that installed software modules are not supported (or words to that effect).
thinking this would mean i could only use up to 4g for now was wrong. it doesn’t allow using the modem at all. it’s disabled by default. enabling it through the gui settings didn’t change anything. changing it through the terminal didn’t change anything.
at this point, i think i’ll need to go directly to quectel for support on this unless it’s already been covered on the forums here. haven’t searched yet.
using nmcli connection show lists the new connection i created through the settings ui upon very first boot. but using sudo nmcli connection up 'connection name' always times out. and using nmcli device show will usually show GENERAL.STATE: 40 (connecting (prepare)) for the modem entry. but it does at least tell me it’s ttyUSB2 for my board.
so then i try echo AT+CSQ | socat - /dev/ttyUSB2,crnl, but this (along with every other AT command i try) always produces the response: Device or resource busy.
for what it’s worth, i managed to find this pdf online - i hope it’s useful to someone. i’ll read through it myself at some point, too:
