Hi Oleg, I understand and tried what you said. The problem I faced for a long time is that
txtsnd: I cannot set the interface, if I use tap0, which will echo: error: invalid interface given. I found the tutorial that said using addr, but I do not have the addr command when I use the R21 board. And what is the mean for interface for txtsnd to use, if I have /dev/tty.usbmodem* MCU device Thanks, Haoyang > On Oct 23, 2015, at 13:50, Oliver Hahm <oliver.h...@inria.fr> wrote: > > Hi Haoyang! > >> The problem I face now is that I want to use the embedded default network >> stack to make two Atmel R21board to send packet with each other through RF, >> before I implemented the a new protocol on Network stack.
