That might be me, different Thomas. ;)
Yes the different networks is very interesting...and definitively a
need....
not sure if it is easily done like adding a second interface on UNIX
with a simple ifconfig (o;
Having two network interfaces is already possible with RIOT as well as
RIOT provides
a ifconfig command for configuration.
The button thing...don't have to be a button..and is also not always
possible...
Let's say you want to deploy a new network....
Idea is like all nodes have a default PAN as the firmware is all the
same (more or less).
You start deploying the network from the border router away by
pressing a button
which tells it to start a join procedure....for example by
broadcasting on that PAN
a message like "who ever wants to joing my new network with PAN ID
xxx, you have 5
minutes time"....
Then on the the next node you press also a button, which then listens
on the
default PAN and accepts then the new PAN advertised by the router
node...
A leave would be then like pressing the button for 5 seconds...putting
it back
into the default PAN....
If I understand your scenario correctly, what you are suggesting
involves a 802.15.4
coordinator announcing PAN or channel changes and/or manages hardware
addresses.
I started a discussion on this topic recently but for now RIOT is still
missing these
"runtime" features.
Please be aware though that, to the best of my knowledge, nothing in the
standard keeps
a device from starting to communicate on a certain channel with a
certain PAN ID at any
point in time.
Best,
Thomas

Hi Richard,
thanks for sharing your thoughts on the list!
I'm not sure I fully understand your requirements, but believe that
some are generically interesting for RIOT, e.g., running several/many
802.15.4 networks in parallel.
What about this join/leave button?
Best,
Thomas

Some of you from #riot-os already know some backgrounds...
I work for a company doing sanitary devices (basically anything
controlling water)
with IoT capabilities...currently WLAN/Ethernet connection only...
To extend our portfolio we would like to switch over to 802.15.4
network...
Target areas would be for example hospitals with hundres od WSN
nodes per building.
In the past I tested so far contiki, skipped totally tinyos and
ended up
with an easily setup riot-os network at home...which was the base to
present to our CEO...
We have already assigned a local company to do a WSN but they failed
after half year to deliver
anything useful. That's why I always kept a back plan from the
beginning evaluating
open source solutions...
I got the OK today to ask here on this list for external men power
to extend
the already great riot-os capabilities with special features we
would need
to be successful in commercial/industrial fields, mainly:
- run independant wsn side by side with not interfering each other
- simple joining/leaving a node to/from a PAN with simple button
press
We would like early as possible..speaking...within two weeks (o;
thanks in advance for listening and
for the already great riot-os (o;
