Does HSMM-MESH reguire exclusive use of the Pi or can it work alongside other apps?

That does indeed sound like what I'm looking for.

I'll set about coming up with a TTL-232 hardware interface (the sparkfun units seem as good as anything to start with) and I'll poke around with this now that it appears that it's likely to work.

Your instructions are a bit sparse for my level of linux experience but I will see how far I can get on my own.  Will turn it into a step by step application article if I can get it to work.

I chuckled at your use of a phone patch as an audio interface.  Quite a marriage of the old and new.

Oh, Mark, so you want more like :

http://www.broadband-hamnet.org/applications-for-the-mesh/158-remote-control-hf-rig-over-mesh.html

but with a TNC instead of the FT-897 CAT-control..Quite doable. Load ser2net on the node, and the serial->IP driver for Windoze and you should be good to go.

And I DO have an WL2K to Mesh connection working, using Paclink and AGW Pro. You tell Pacllink to call a remote AGW at the mesh node name(in this case the mesh name is K5KTF-10, same as the WL2K station), port 8000, with user/pass, and paclink then controls my WL2K station radio. From anywhere on the mesh. I was at the 2011 HamComm in Plano, and we had a mesh tunnel back to Austin. I then did this to my K5KTF-10 station radio to check email at the one local hospital WL2K station down here, but controlling it all from ~300 miles north.

See http://www.broadband-hamnet.org/applications-for-the-mesh/149-aprs-rx-only-igate.html for a taste of attaching a TNC.

I dont think there is a way to use the Adv Svcs page to work this. At least not yet.

This would probably have to be done via the command line.

EDITING: My bad, I forgot I did this with a USB-Serial adapter. But yes, if you get a level shifter, you can tie it directly to the serial port (recommend the second COM port, as the first defaults to console mode). We have a guy working on some code that may allow a WRT to act AS a TNC, but at 119200 instead of the butt-slow 1200 baud WL2K speed, so that he can use Airmail/etc at something faster than 1950's speeds.

Wanting to give my HSMM node something to do, I thought about interfacing a packet TNC to ttyS1 and offering a 2M packet gateway via HSMM.

How would you access the serial port through the advertised services from remote nodes?

I understand TTL to 232 hardware is required. 

Thanks.

Hi Joe,

I have a friend in Fremont who is planning on setting up a node with my help. Not sure when it will go live, maybe after next weekend. So check the map every few days. Maybe we will have it up and running and on the map by then.

If you have your node setup already, post it to the map and we will try aiming your way in a week or two.

Hi there Rogier,

I read your post and thought you might like to check out this conversation thread: http://www.broadband-hamnet.org/hsmm-mesh-forums/view-postlist/forum-11-sfbay-area/topic-787-saratoga-fremont-san-jose-mesh-network-plans.html

If you set up a node try listing it on the map: http://www.broadband-hamnet.org/googlemapped-mesh-nodes.html

Tyler, With a building in the way I think it will be difficult for our two nodes to connect. If you leave yours up and running I will try to aim my antenna your direction sometime this week or next weekend.

Try to position it near a south facing window.

This is almost identical to the directional wifi antenna I currently have: ( http://www.amazon.com/Alternative-Wireless-Pole-Mount-Directional-Antenna/dp/B003LY6VHI/ref=sr_1_30?ie=UTF8&qid=1393827523&sr=8-30&keywords=wifi+directional+antenna )

Obviously the higher the dB gain the better. Here is the antenna I am considering buying next: ( http://www.amazon.com/Silver-802-11b-Wifi-Antenna-Rp-sma/dp/B00DSVPAGM/ref=sr_1_10?ie=UTF8&qid=1393827828&sr=8-10&keywords=25dbi+wifi+directional+antenna )

Just make sure you don't use a very long coax cable between your node and the directional antenna you eventually get.

I know we currently don't have good odds of making contact with each others nodes or the one in Milpitas. However I think if we both set up nodes and list them on the map: ( http://www.broadband-hamnet.org/googlemapped-mesh-nodes.html ) other hams will see that there are new nodes showing up in the area and that might be the extra push they needed to do the same.

I think contacting our local ham clubs to ask if they have any mesh nodes setup in the area would be a good idea. If so suggest they list them on the map. If they don't have any mesh nodes then suggesting this as a project for their group to work on would be a good idea that they will probably appreciate.

I also plan on talking to several other hams I know into setting up nodes of their own. I think if we can get the ball rolling then this could easily snowball into a decent sized bay area mesh network. Feel free to post a message on here when you get your node listed on the map and I will do the same sometime this week.

Good luck,

James KH2SR

This device looks like it ought to help me make sure the right voltages are getting to the right pins:

Hi James,

I suspect my building is going to make this a pretty big challenge.  My patio is on the main floor of a 2 story apartment building.  My lease terms make it clear that I cannot put anything on the roof either.  South of me is another building as well.

If you wanted to see how my location would fare, give it a shot:

http://www.heywhatsthat.com/main-0904.html?view=K88E04SK

Very nice website.  Looking at it, it should theoretically be possible to get the signal through if we had good line of sight.  Hmm, being new to the area I didn't realize how much the elevation changes from North to South, but then I guess I shouldn't be too surprised. :)

What kind of antenna on Amazon would you recommend?  There seems to be quite a range from cheap non-directional  antennas to fancier directional ones.  

I'd try a dish, but I suspect I'd be out of luck for aiming it South.

Thanks,

Tyler

So I have not seen an official spec, but Mirocom sales site and some other reports I have seen seem to suggest 10vdc is OK to run these on so that means a 12v battery charge/discharge range is in the avaliable power range.

What you want is a PASSIVE POE INJECTOR with pins 4/5 as Positive and 7/8 as NEGATIVE  pins.

If this is a field setup you can probably get away with the really simple one such as follows: (I found it more expensive to try and make one so I didn't bother and went straight to buying though i haven't used any of these below yet) (Hint: just cut the ends and put Anderson on them)

http://www.amazon.com/HCP05-Passive-Injector-Splitter-Connector/dp/B00DZLSRJC/ref=sr_1_1?s=electronics&ie=UTF8&qid=1393814600&sr=1-1&keywords=passive+poe+injector

http://www.amazon.com/Passive-injector-Power-over-Ethernet/dp/B00EBCGJVW/ref=sr_1_4?s=electronics&ie=UTF8&qid=1393814600&sr=1-4&keywords=passive+poe+injector

(NOTE: always verify the pins before connecting an unknown POE injector to your device to avoid destroying it)

If you need to power several (such as I need to for the programming lab)  I have actually used:

http://www.amazon.com/WS-POE-8-ENC-Multi-Passive-Injector-devices/dp/B0075F7F2O/ref=sr_1_3?s=electronics&ie=UTF8&qid=1393814600&sr=1-3&keywords=passive+poe+injector

(at any given time 4+ have been plugged in and active in my lab off my central 13.8 supply)

If these will be outdoor permanent installs, especially if you get lighting,  I recommend something a bit more protective however with built in lighting protection such as:

http://www.l-com.com/power-over-ethernet-single-port-cat5-passive-poe-midspan-injector-w-integral-lightning-protection

If you will be trying to run these in a car with a motor, I don't know how well the on board SMPS handles up and downs. A capacitor on the power lines may not be a bad thing in a car deployment. I have  planned to be preemptive and instead install as 12v to 16v dc-dc switcher to bring the voltage up and clean it up for car usage but I have been known to over engineer.

I also plan on using the dc switcher to allow me to dump a battery at the bottom of a hill and run up to 300ft of CAT5 up to the top of a hill (Higher voltage, less current less system losses.) This also applies if you have a long run from your power source to your Ubiquiti device.

Useful calculator for POE voltage drop: http://blog.fosketts.net/toolbox/power-ethernet-calculator/

I am new at working with Power over Ethernet.  Is there an easy way to provide PoE to a Ubiquiti router from a standard 12VDC power source?  I know I could use a 12VDC to 120VAC inverter but these are typically in short supply and a bit expensive.  Ideally I'd like to somehow be able to power a Ubiquiti router from PowerPoles.

Thanks to those who ported the BBHN firmware to the Ubiquiti hardware.  I now have a Bullet and AirGrid both running BBHN and I really like the devices.

The 0.0.0.0/0 route should show up in the OLSR status screen as I recall (however I can't check on mine right now)  as an HNA annoucement.

No GUI exists to see the full routing table at this time.  You would need to log into the node and run the route command manually to see the actual routing table.
