I noticed the website http://wpan.cakelab.org/ mentions a bunch of boards. Some of those pointers don't work and the ones that do, show standalone boards that need to be wired up to a SPI bus. I assume the SPI bus is easily found on a rPI-like board. Is it difficult to hook one of them up to an x86 desktop? Thanks in advance.

Yes, it's a bit painful since few desktops have easily accessible GPIO pins that you can turn into a SPI bus. You can add one with a FTDI USB interface easily, but given the cost of an RPI... hard to argue. -- ] Never tell me the odds! | ipv6 mesh networks [ ] Michael Richardson, Sandelman Software Works | network architect [ ] mcr@sandelman.ca http://www.sandelman.ca/ | ruby on rails [ [-- Attachment #2: signature.asc --] [-- Type: application/pgp-signature, Size: 464 bytes --] ^ permalink raw reply [flat|nested] 8+ messages in thread

Pretty simple. Just want to see how well the technology works. With all the industry's talk about IoT, we are just trying to set up in our lab various technologies that customers may ask us about. And we want to see how well it works with our products. :-) > > The at86rf233 is popular and easily obtainable and Alex is doing lots of work > to support it. Get the openlabs device.

Is it difficult to > hook one of them up to an x86 desktop? You might be able to do this with some USB dongle exposing some GPIOs to to the kernel but I never used anything like that. Most of my transceivers are connected to Pi's. So it goes down to embedded. I'm in the lucky position though to have two ATUSB dongles which are simple USB dongles and get connected to your x86 systems with ease. They work out of the box in mainline since 4.1 and the firmware is open source as well. The problem right now is that it is now longer being sold. We are working on changing this though. See my mail from a few minutes ago to this list about interest for a new ATUSB production batch. Right now we would estimate them being on sale again sometime in October (the smaller fabs we are using for SMT is on holiday and we also need to prepare things in our spare time). If this is to far away, fair enough. If it does not really matter to you and you would have an interest to use them please let me know so I can better estimate the needed number of devices for the batch. regards Stefan Schmidt ^ permalink raw reply [flat|nested] 8+ messages in thread

One can use various dev boards to run OpenThread, such as Zolertia's RE-Mote or TI's CC2538 dev kit. Alternatively, there are also very good kits from SiLabs, NXP (Freescale) and Dialog (check OpenThread Sandbox Development Platform). From a Linux perspective, it might be worth playing with OpenThread and wpantund, a user-space 15.4 driver that talks to 15.4 radio chip over UART or SPI. In this setup, one could flash 15.4 with OpenThread and run wpantund on a Linux host to create a Thread network gateway, which typically is used by low-power 15.4 only devices to get outside of the Thread network.

We are aware of them and I already has some mails with Jonathan from Nestlabs to see how we can work together here. In this setup, one could flash 15.4 with OpenThread > and run wpantund on a Linux host to create a Thread network gateway, > which typically is used by low-power 15.4 only devices to get outside > of the Thread network. What you are describing is the network co-processor setup (NCP). This sadly means that Linux is only aware of the very high level characteristics of the Thread network. IP address range, routes, etc. The rest would all be handled in the device firmware. With OpenThread this would be at least open source. On the other hand the linux-wpan and 6LoWPAN stack we are working on here is capable of handling the PHY and MAC layers as well. Thus we are aiming for a way to run the higher level bits of OpenThread in userspace while having at least 15.4 and 6LoWPAN be dealt with by the existing subsystems. I'm working my way through the code right now to see what is needed on our side to support the OpenThread use cases and what interfaces we would need to offer. I should be able to but some initial thoughts into the wiki by the end of the week maybe. In my opinion the NCP as well as the native linux use case are both valid and it depends on your idea or project/product what you want to use. regards Stefan Schmidt ^ permalink raw reply [flat|nested] 8+ messages in thread

I don't see an archives for this mailing list, so I can't see your previous email. How much would this cost? I might be up for buying 5 or so.

How much would this cost? I might be up for buying 5 or so. One archive is on spinics.net. Here is a link to my mail about this topic: http://www.spinics.net/lists/linux-wpan/msg04084.html As you can see we are estimating how big the production batch needs to be. The price point would be 50 EUR with a little hope to cut it down a bit. We can't make promises on the later one though. I will keep the list informed. regards Stefan Schmidt ^ permalink raw reply [flat|nested] 8+ messages in thread
