So while both are likely possible they're not recommended. I should know better. My brain gets going and occasionally forgets about the whole constrained device aspect. I suppose it would make more sense in both cases to use something that looked more like the Linux based IoT-A8 device (though, I'd probably go with the NDA free Freescale iMX6) with a few radios and wired Ethernet and/or wifi.
Then again... I suppose with Hauke's recent ENC18j60 work it might make even more sense to use how ever many cheap single band 430 devices plugged into an Ethernet switch. Hmmm... I wonder if enough power could be siphoned off a non-POE switch to power a small micro like a 430 and a 15.4 radio. Anyways. You make good points about routing overhead and buffers. Routing should be left to the big 110/220 Linux boxes with their endless supply of RAM. Thanks for the quick reply. --adam On Tue Nov 11 2014 at 1:58:35 PM Martine Lenders <[email protected]> wrote: > Hi Adam, > > 2014-11-11 22:43 GMT+01:00 Adam Hunt <[email protected]>: > >> This reminds me...
