Any help would be appreciated.
The procedure looks right in general. A few questions to debug:
* do you use different ESSIDs for the IBSS-networks? ad-hoc devices joining
may override the configured channel
and select another IBSS-network instead when it has the same ESSID.
* have you confirmed that the WiFi connection works without batman-adv? just
set up your WiFi, configure different
IP addresses and ping for each hop to test.
* does the output of "batctl originators" helps you? Are the other nodes
displayed on node 4?
