tock-ping

Ping app used to verify the Tock OS 6LoWPAN/IEEE 802.15.4 stack implementation. Forwards IPv6 ICMP packets to and from the Internet via Linux.

End goal is a setup like this:

[imix running Tock OS]  )))  (((  [imix running Tock OS] <----> [Raspberry Pi running Linux] <----> Internet

The second imix will transfer packets to and from the Raspberry Pi using SLIP.

Files in this repo:

• serial_log.py: Reads from serial on the Raspberry Pi and prints to the console.
• tun_ping.py: A first stab at stuffing raw bytes into a Linux network interface by setting up a tunnel device.
• setup_interfaces.sh: Sets up wpan and lowpan interfaces on the Raspberry Pi.

Files related to this repo:

• radio_rx_slip_tx/: Tock userspace program that implements SLIP in one direction. Writes all radio packets received to serial using printf().
• lowpan_frag_dummy.rs: Tock kernel space program that sends ICMP packets over IEEE 802.15.4.
• pyCCSniffer: Uses a Texas Instruments CC2531emk USB dongle to sniff packets, dissect them, and stuff them into a WPAN interface on Linux. @ptcrews and I were using this to develop the outbound side of the ping app (the TI dongle can only receive IEEE 802.15.4 frames, not transmit).
