The goal here is to enable low bandwidth but adhoc ip networking. I had set up a pair of radios to connect using pppd and I was wondering if I could utilise batman to try and create a mesh. An example of setting up the serial ports as ppp interfaces: $ sudo pppd /dev/ttyUSB0 57600 noauth nodetach 10.42.5.5: That works fine but applying batman to that interface was unsuccessful. I think that was due to limitations in the ppp and interfaces created by pppd: e.g. $ sudo batctl if add ppp0 Error - failed to add interface ppp0: Invalid argument The interface ppp0 was specified as POINTTOPOINT e.g. $ ip link $ ppp0: mtu 1500 qdisc fq_codel state UNKNOWN mode DEFAULT group default qlen 3 I'm not an expert in this so don't have full visibility of all the tools available. I was wondering if there were better ways to set this up, possibly not using pppd? Any guidance would be appreciated. cheers Peter
