Thank you, with "iw", it works!
I downloaded "iw" ARM binary from here:http://www.onlyxool.net/porting-iw-tools-to-android/
Serval still uses "iwconfig", and "iw" does not work with some devices,
for example my Motorola Milestone:
# iw dev tiwlan0 info
nl80211 not found.
I added the missing glue to Serval for detecting and driving Galaxy
Nexus chipset using "iw":https://github.com/rom1v/batphone/commits/gnexus
- the "iw" binary;
- the detection and edify scripts for Galaxy Nexus (using "iw");
- a new variable in adhoc.conf for the frequency ("iw" expects
a frequency, not a channel);
- a new check for detecting the network interface state for chipsets
with flag "nowirelessextensions" (it tries with "iw" before fallback
I also needed to change the target (in project.properties) from
android-8 to android-10, but I kept minSDKVersion and targetSDKVersion
to 8 (in AndroidManifest.xml), so it will still work on phones from
android-8, and calls to elements not available in android-8 need the
@TargetApi annotation. Indeed, I needed *NetworkInterface.isUp()* method
available from android-9 (but android-9 does not exist anymore), because
"iw" gives a network type even if the interface is down, so we must
check (only if Build.VERSION is at least 9) if it is up. If it is a
problem, we can call "ifconfig" and parse the result instead.
With these changes, Galaxy Nexus works perfectly with Batphone. Thank
you for your implementation of ad-hoc mode for this device.
Note to serval developers:
If you agree to merge my changes in, you should recompile the "iw"
binary: we have no reason to blindly trust onlyxool (the blog from where
I downloaded "iw"), and you have no reason to trust me (or anyone else)
including such a binary blob into Serval.
