You're quite correct that this is an oversight of ours. I thought Trenz had already put the schematics etc on their website as they are manufacturing the PCBs and selling the units for us (we are currently between the 100 devkits having gone out, and being ready for pre-order for final machines, so unfortunately you can't just yet order one, but later this year we expect to open pre-orders). We will solve this one way or another.
While the final machines are not yet purchasable, you can buy an off-the-shelf Artix7/Nexys4DDR FPGA development board and run the core on that. This has been supported for several years. Also with 100 devkit machines sold and in people's hands, its definitely not vapour ware.
One of the other things we have been doing with Serval in the Mesh Extender devices is making it possible to connect external radios, including HF radios from Codan and Barrett, for really long range inter-cluster communications.
Yes, we know we need to fix the website and app store. This is the pain of depending on grants to get work done :/ Getting the app back up on Play Store is our current priority.
Howdy,
as the founder of the Serval Mesh adhoc networking protocols and hardware, what I would look for in a new radio is:
1. True packet radio mode, that doesn't hide the radioness of the link etc, but lets the programmer use it's strengths.
2. UART link, ideally using 3DR/RFD900 compatible connector (then we can include it directly in our existing systems, and so can others).
3. Field-flashable, but with robust protections on the boot loader, as it is not uncommon for a radio to be on the boot serial interface, on hardware that has only one serial port.
4. Support 434, 868 and 905-935MHz ISM bands.
5. Use advanced interference tolerant wave-forms, like Chirped Spread Spectrum or even something better.
6. Fully open chipset/firmware design, so that it can be truted.
Anyway, poke me at paul@servalproject.org if you would like to talk further about it.
