Frequently asked questions

Q: Does CCN-lite support 8-bit MCUs on RIOT?
A: Short answer, no. Most integer types in CCN-lite are {u}int32_t and need to be set to the (correct) size. This is already a todo item on our Roadmap


Q: In RIOT NDOs are delivered to the loopback face, while the Interest originates from another node. Why?
A: Check if the last two bytes of the MAC address of the devices involved match. By default in RIOT and IEEE 802.15.4, short addresses are used (which are 2 bytes). A node might misinterpret that the Interest originates from the same host if short addresses are used. A workaround is to increase the length of the short address using RIOTs ifconfig command. For further information see also #239

Q: What happened to NFN support in CCN-lite?
A: We discontinued the support of NFN in CCN-lite and NFN-scala. NFN is continued as a part of PICN which is designed to be easier to use. NFN in PICN contains new features and is covered by many test cases to provide a stable NFN experience. You can find further information over here. The last release of CCN-lite which supports NFN is 2.0.1, which is compatible with NFN-scala 0.2.1.
