This is cool stuff. But, what we really need for this to be done on _open_ platforms is for someone to code up a Bluetooth 4.0 alternate-PHY thing for some open source operating system that lets one glue the BT and wifi stacks together so they can dump data where appropriate. Now, for the real feedback: * bluetooth is lower power and shorter range, but it's also much lower throughput (compared to 11n) for the same range to an adjacent device; * it overlaps the whole 2ghz range, so if you're doing a lot of bluetooth transmit, you're interfering with nearby 2ghz wifi devices; * it also will be an "or" with the onboard wifi - ie, you can't transmit bluetooth and 2ghz wifi simultaneously on a lot of chips. There's an antenna switch that stops you from doing this; * almost none of the open source stuff has sane transmit power or rate control hooks that would let you get away with much higher density 2ghz meshing - why transmit at full power if you're only talking to someone 3ft away? I like what you're doing but a lot of what you're doing is tucked away in closed source blobs. It's hard to implement that on more open platforms. Once people here get their (atheros!) mesh hardware doing much more useful things, I'm happy to sit down and do more brainstorming in relation to what you can do with the hardware and how you can do evil things at the 802.11 layer. -adrian (still hacking away at TDMA and 11n in his spare time..)

Hopefully this brings some inspiration and answers some questions (ex. Mitar: Why Bluetooth?) Also, please excuse my lack of participation this past month - I'll be back in the action next month. I'm also going to a festival called Libertopia <http://libertopia.org> this weekend in San Diego where I'll attempt to spread the word. These people are really into alternative, decentralized services. I'm starting my drive down tonight so have a great meeting and enjoy the weekend everyone!

Hi! I must say that I still don't understand why Bluetooth, but probably is mostly related that it is easier to control on current mobile platforms? So lowering power on WiFi and configuring IP stack there probably requires root. I am not sure if Open Garden requires root?

It does use lower power, yeah. but it's significantly lower range. I can jack the tx power on the atheros cards down to 0dBm into the antenna and transmit for very short periods of time. It draws noticably less power than at full power, but still draws power. Receive is also quite hungry. -adrian On 24 September 2013 15:33, Marc Juul &lt;juul(a)labitat.dk <mailto:juul@labitat.dk>> wrote: On Sun, Sep 22, 2013 at 2:28 AM, Mitar &lt;mitar(a)tnode.com <mailto:mitar@tnode.com>> wrote: Hi! questions (ex.

I would also guess that bluetooth still consumes significantly less power than wifi even if wifi is set to lower power, but I don't actually know. -- Marc _______________________________________________ mesh mailing list mesh(a)lists.sudoroom.org <mailto:mesh@lists.sudoroom.org> http://lists.sudoroom.org/listinfo/mesh _______________________________________________ mesh mailing list mesh(a)lists.sudoroom.org http://lists.sudoroom.org/listinfo/mesh
