Whether

Hi,I want to buy a physical board to achieve ICN communication based on RIOT. I want to know whether it must have a radio chip on the board? However,I find the stm32F4discovery does not have any radio chip Can anyone tell me what should I do? Thanks a lot.

Hi,

at least you need a network interface and therefore a radio chip makes much sense. Cenk already proposed three platforms:

... but you can also chose other ones, for example an stm32f4discovery board. In that case I propose to buy an external 802.15.4 transceiver such as the one from Openlabs[1] or Microchip[2], connect it via jumper cables and try out the ccn-lite-relay example.

Best Peter
