Hi Sam, Thanks for contacting us. I'm not sure I can speak too much to the routing, but we do have a network simulator written in Python, that you can play with here <https://jemucino.github.io/disaster-radio-netsim/>, and the code is available here <https://github.com/sudomesh/disaster-radio-netsim>. The main problem I see with MDP is that it is a Layer 3 protocol. I know we are not using the LoRaWAN Layer 2 protocol and only using the physical layer LoRa modulation scheme. Also, we are concerned about bogging down the network with too many acks and re-transmissions. Not sure if @juul or some of the SSB people might have more to say about possible routing schemes. As for the hardware, we only have a few prototype boards that had some minor problems. Once we finish the updated design, your best bet is to probably get your own printed, as we have a number of people in Oakland and NZ waiting for boards. The KiCAD schematics are available here <https://github.com/sudomesh/disaster-radio/tree/master/hardware>, though you should wait for @nanomonkey to tag another commit. Happy holidays! - grant/@paidforby On Wed, Dec 13, 2017 at 9:41 AM, &lt;samuk(a)disroot.org&gt; wrote:
