Принимаем стандарт IEEE802.15.4-2003 по технологии SDR(Software Defined Radio)
IEEE802.15.4 - стандарт для беспроводных персональных сетей с низким уровнем мощности сигнала в нелицензированных диапазонах частот. Он определяет физический уровень и MAC уровень доступа к среде. В этой статье рассматривается физический уровень, версия 2003 года и OQPSK модуляция.
Another alternative I found is @RIOT_OS.
I face here the same questions as for the Zephyr RTOS:
- can IEEE 802.15.4 be freely used without any membership fees,
- how much of application level and API(s) needs to be custom-developed on each side (device and integrations).
I found @zephyr as an alternative, but I'm not sure whether the IEEE 802.15.4 can be freely used without any membership fees.
And, that's also quite low level/layer protocol. So, I guess, that application level integrations would need be custom developed.
Where Zigbee and Z-Wave standards define also application layer and API(s), and devices can be self-describing (at least in Z-Wave, not sure about Zigbee).

Can Contiki NG and Linux communicate via 6LoWPAN / IEEE 802.15.4?
