[Bug]AdvAir.sh cannot write to /tmp

[CharlotteWlkr86]

Paste of Logs:

The problem is that AdvAir.sh writes to /tmp directly which gives permission denied.
Linux on the Sony is via termux, like a docker image where temporary files are only accessible through
the proper call to mktemp. For instance:
mktemp --suffix=myFile
/data/data.com.termux/files/usr/tmp/41Iun75mtymyFile
As such, AdvAir.sh incorrectly creates temporary files.

Cmd4 Config:

Hi, Can you please try from within termux to see if the global environmental variable TMPDIR is available by echo $TMPDIR The reason I ask is that some distros handle mktemp differently. Some have the prefix as you have shown, some use a different template style. Congrats on getting Homebridge running on an Android TV. I do not know if I would be so brave :-) Thanks, John Talbot

Thanks for the quick response John.
I checked termux
echo $TMPDIR
/data/data/com, termux/files/usr/tmp
touch $TMPDIR/itworks
This is also an answer,

Thanks for replying to this one in my absence John, I have no experience with termux.

I am also very intrigued by Homebridge running on an Android TV; this project is slowly getting to all sorts of devices!

@CharlotteWlkr86 I was wondering if you might be able to provide a little more information on this issue? Is it just that you cannot access the error logs due to it not being able to write to the folder? Or does this not allow the entire plugin to work? I imagine the latter may be the case as it cannot access some of the constants we are writing there. Just trying to understand the issue a little better.

@mitch7391 A learning experience for sure. termux is CML driven. apt installs nodejs and npm installs homebridge. My network devices already are already pinged with CMD4. homebridg in debug mode just gave me AdvAir.sh was failing, so I gave that a go from the termux prompt and found the permission denied errors to /tmp.

Hey Mitch, Both my Sony TV's are newer models than hers. termux is available through the Google Play store. Charlotte's problem made me look it up. Many years ago I got Kodi through the Google Play Store and it was blazingly fast. I never had seen homebridge in the Google Play Store and have learned something new with termux. Ttyl, John

Awesome, this is a good find thank you @CharlotteWlkr86! John has emailed me a potential solution to this for us to add and test in the next beta. I will leave this issue open until then.

Hi Charlotte, Sorry for the delay. We would like to know what kind of device $TMPDIR is on. Is it RAM or Flash. Can you please run the following command and send us the results. df $TMPDIR thanks, John Talbot

Hey @CharlotteWlkr86 just curious to know if v3.4.0 had resolved your issue?
