[Olsr-users] Olsrd seems working on Samsung Galaxy S4 handsets but no neighbor is shown

[Justin Lewis]

Hi,

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

I've checked that:

   - 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)

Note that:

   - 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 any
of the Samsungs:

   - 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
