Re: [riot-devel] 802.15.4 for Linux

[Martin]

Hi,

we have the R-IDGE 6LoWPAN router USB sticks running on Linux. We 
succesfully made them talk with the samr21-xpro and the iot-lab_M3.
But, currently no unicast communication was succesfull from board to 
stick only with multicast address as next-hop.
However, we succesfully transmitted UDP packets forth and back using 
multicast next-hop.


As Raphael wrote, when plugged the stick is directly recognized by Linux 
as NIC and shows up on `ifconfig`.
The 6LoWPAN specific configurations, such as setting the PAN/context or 
the channel, are made with a provided configuration tool (cfgtool [1]) 
which can be built from source.
There is also a RPL Edge router daemon available [2], which we want to 
test with the boards.


Best regards,
Martin

Dear reasoning IoTlers,

I know, we had this question already several times before , but I'm 
not sure
about the current state and if some of you have made new experiences 
in this
domain: is there any off-the-shelf hardware available that provides 
an IEEE
802.15.4 interface for Linux systems - preferable something like a 
USB stick?
If yes, does this hardware work with a standard Linux vanilla kernel 
and which
version is required? Or does it need any custom/developer version of 
a driver?
How well are upper layers like 6lowpan supported by Linux in the 
meantime? And

has anyone ever tried to connect such a device to a RIOT driven device?

Thanks,
Oleg

Hello,

ah, sure. I did not connect "tests/malloc" to the path in RIOT. Thanks for the 
clarification.

Hi,

we have a couple of these USB things [1]. Martin has made a few tests with 
them. If I am not mistaken the sticks show up on Linux as a network interface 
without any problems.
