Re: [lwip-devel] 6lowpan support in lwip

[Ivan Delamer]

Hi,

What is available is the patch in Savannah.

I have been testing it in a product for over a year and it works quite 
well.

It is not 100% complete, and lacks documentation. But if you're a bit 
of a hacker you'll figure it out.

The 6LowPAN code is implemented like a netif, but you'll have to 
implement your own driver for your PHY/MAC. I used an AT86RF231, so you 
need to write the driver to write the packets via SPI. That depends on 
your CPU and your external PHY.

I haven't had time to document it and merge, but if you want to improve 
the code we could look into merging with master.

Cheers
Ivan
