"Edge Router Design"

Other Parts Discussed in Thread: CC2650, CC3200, CC2531, CC2630

Firstly i'm very new to 6LoWPAN, and trying to get my head around it, so if the questions seem a little odd, please forgive me.

I'm currently working on another project with a TI CC3200 and a CC2650, where the intention is to provide a Wifi --> Bluetooth Gateway..  The issue that i'm likely to face is that i'll only be able to connect to a few devices at the same time. ( max 3).. 

It struck me that the CC2650 can run other protocols and i thought that just maybe  we might be able to to use this same bridge as a way to connect to many more devices..    

Could the 2650 be used as the 6LoWPAN edge router ( if its connected to something more powerful, like a CC3200 ).    In the Contiki-6LOWPAN wiki, i see that a Beaglebone and CC2531 is used.  This is a possible option, but not nessarily ideal..  

I'm hopeful someone can provide some guidance.

 

  • Hi Andrew,

    CC2650 can act as an Edge Router. The main issue with that setup is that it need to store routes to all its children, which requires RAM. I think the default setting is to allow 20 'childs'. You can test this directly by using the /examples/ipv6/rpl-router example and build for cc26xx. Just make sure to use bleeding edge Contiki. Another setup is to use CC3200 as host MCU and let the CC2650 run like a network processor. This application is called SLIP-radio in Contiki source tree,a nd is a very common setup in systems. There is no CC3200 Contiki port I am aware of, but the platform with CC3200 and CC26xx is very compelling!

  • Hi Jonas,

    I am already planning to use CC3200 and CC2630. Do you know if there is any CC3200-CC2650 example SW?

    I am planning to use 4 pin SPI connection and 1 pin SPI-slave to interrupt SPI-master to fetch data from the slave. Would you recommend a different interface (4pin UART) or a pin set-up?
  • Yes, the 2600/3200 platform is very compelling, And shouldtn be too hard to establish.
