Dear RIOT-developers,
up to now I have worked with a beaglebone as a 6LoWPAN border router.
I want now to change to a microcontroller based system (STM32 family).
Now my question - what is the minimum clock speed of such a controller to be able to work as a border-router?
Thanks a lot!
Best regards,
Neo
Hi Neo,
regarding clock speed Iām not aware of any restrictions on the gnrc_border_router
example (though there are some on space, which most STM32 MCUs should fulfill). It might get slower and depending on the traffic it might get overwhelmed, but I think no one ever made any experiments for that specifically.
Best regards,
Martine
Hi Kaspar,
I'm just searching for a very small device - and the device I have in my focus STM32L432 is running at it's nominal speed of 80MHz.

Hi
We have 6LoWPAN border routers running on Contiki OS and TI CC1310 @ 48 MHz ā RAM is the main issue, 20k is enough for up to ~100 nodes in the network. No heavy traffic, though ā except OTA fw updates, but we perform them one by one, not simultaneously.
I believe RIOT should have similar or lower hardware requirements, so a border router on STM32L4 should be fine.
