*Hi Teco, *
Thanks for your concern and sorry for the late reply
I will be happy to share my result with you and anyone else who is
interested in adhoc networks.
here is the information you asked for;
1. I am using three Samsung Galaxy S4 (International) GT-I9505
2. The SGS4-handsets and other Nexus-tablets are operating under
CyanogenMod 10.2 (I've downloaded the pre-build source code and installed
it from the ClockWorkMod recovery)
3. The OLSRD version is 0.6.6 (downloaded from
http://www.olsr.org/?q=download)
Regards the network issues:
1. The Samsung that establishes the network can see and ping all the
other Nexus-tablets that are connected the network.
2. The other Samsung-handsets see and join the network but can't see or
be seen by any other node in the network
3. therefore, I'm NOT sure that the SGS4-handsets are connected (except
for the network-establish-er)
4. my "pinging" problem is strange, because if i create a new adhoc
network from another SGS4-handset then again it can see and ping all the
Nexus-tablets that are connected and can't see the other SGS4-handsets.
5. I am NOT implementing any smart Gateway.
hence:
1. all SGS4-handset can create an adhoc network
2. the adhoc network is seen by all the SGS4-hansets
3. when asked to join the adhoc network, and after couple of seconds,
all SGS4-handset show this notification: "(IBSS Name) Ad-Hoc Connected" in
the Wi-Fi settings) which indicates that they see the adhoc network and
they join the network (and it doesn't matter who established it)
Note that:
1. if the Wi-Fi feature is turned off and then again turned on, even the
Nexus-tablets can't be seen from the adhoc SGS4-establish-er (and of course
the other SGS4) . Besides, unlike before, the Nexus can't see ALL the
SGS4-handset (including the adhoc establish-er )
2. if the Wi-Fi is turned off from the SGS4 (the establish-er) , the
Nexus-tablets can still see each other and OLSRD can run normally.
3. OLSRD configuration file that is running in all the handset is the
same
4. OLSRD is running normally in all the devices that can see and ping
each other
5. which means it runs every time (as long as the Wi-Fi doesn't restart)
between the SGS4 (adhoc establish-er) and the Nexus-tablets but does not
work between the SGS4-handset themselves
Hope I've explained how my networks operates and looking forward to her
from you
best regards

Post by Justin LewisHi,
I'm also having the same problem with the S4. I would love to get it
working, so I'd be very interested to hear your results.
Cheers,
Justin
OK, let's try to get it running.
I have GS4A International GT-I9295 (same WiFi chipset as S4, I think).
I run CM 10.2 (Android 4.3.1), custom build.
WiFi in ad hoc is work in progress.
Shall we take offline detail discussions on howto get WiFi in ad hoc, and
post results afterwards?
Then, olsrd on working IP interface would be easy. Perhaps I can help you
before I have ad hoc mode working.

Hi
- IP-address on each Samsung-phone is static and correct.
- Netmask on each Samsung-phone is correct
- Gateway IP-address on each Samsung-phone is its interface IP-address
- All Samsung-phones are connected to the same adhoc network (beside
additional three Nexus-7 tablets)
- the adhoc network does not require a password
- I have three Nexus-7-tablets run an adhoc network perfectly using
the same ".conf" file
However, I noticed that whenever I create and run an adhoc network from
- each of the other two Samsungs can discover the IBSS and join it.
- each of the three Nexus-7 can discover the IBSS and join it.
- the adhoc-creator-Samsung can only see and ping the Nexus-tablets (I
used "Fing" android-app)
- any Nexus can see and ping adhoc-creator-Samsung and the other
Nexus-tablets only (I used "Fing" android-app)
- any Samsung already-joined-the-adhoc-network can't be seen
by adhoc-creator-Samsung or the Nexus-tablets
Hence, I can assure you that the network connectivity is fine, at least
between the Samsung and the Nexus. So, I took step forward and installed
OLSRD on one Samsung (which I used to create an adhoc network). the OLSRD
works perfect between the adhoc-creator-Samsung and the three Nexus-7,
taking into account that OLSRD didn't show any neighbor in the other two
Samsung-phones who, by the way joined the adhoc network (although they
can't be pinged)
My question is why OLSRD does't work between the Samsung-phones ? please
help .. I am getting really confused
Thanks

Time to grab a notebook with wifi-card and run Wireshark to see what
is transmitted over the air and what is not.
I would suggest not running the routing protocol until you have fixed
the link issue, because it complicated debugging the situation. Check
for the easy things first (ip addresses, netmasks, wifi passwords)...

Thanks Mr. Henning for your reply ..
I've tried pinging between two of these Samsungs but I failed, I am
getting
"Destination Host Unreachable"...
I am also unable to perform the troubleshooting in the link you have
send me
(as the "iwconfig" doesn't exist in Android).
However, from the troubleshooting link, I can see that it has nothing
to do
with OLSRD and it is a networking issue that CyanogenMod is responsible
for.
Something is keeping these handsets hidden from each other, but at the
same
time allowing them to discover the IBSS and connect to it.
Thank you

Post by Henning RoggeHi,
can you ping the direct neighbors of the S4 (or can they ping the S4)?
This should be possible without Olsrd running, so you should test this
first.
