…example

add microcoap example application

…ofix

sixlowapp: fix small typo

…ll_commands

RIOT-OS@426170b

sixlowapp: rename thread related constants

…gnore

git: added .gitignore, copied from RIOT

Provide an application for openwsn

This application was not adapted to
RIOT-OS#3162 and
RIOT-OS#3188

…etif_default

ng_sniffer: added ng_netif_default

Related and dependent on RIOT-OS#3555

…hell_uart

ng_sniffer: use uart0 only for none newlib boards

…rm/remove-old-app

sniffer: remove old application

…etwork_stack_apps

remove apps belonging to the old network stack

Was accidentally removed and is also updated to current gnrc.

sniffer: re-add sniffer

spectrum-scanner: Application for radio ED scanning

sniffer: add script, moved from RIOT main repo

Since the device is in raw mode, we don't have any network layer
modules included and we subscribe to `GNRC_NETTYPE_UNDEF` it is safe
to assume that `pkt->next` in `dump_pkt()` is the `gnrc_netif` header.
This only contains GNRC-internal information and should thus be removed
from the dump (though Wireshark seems to be okay with the extra bytes,
a reader of the raw data might be confused).

Since this header however contains the LQI, which the sniffer claims to
output but always returns 0, the LQI value in the `gnrc_netif` header
is read and set before the deletion of that header.

Usually we have a message queue for threads handling GNRC netapi calls.
Maybe the absence of one in this application contributes to the packet
loss reported at various places.

…g_queue

sniffer: add message queue for dumper thread

The sniffer RIOT application doesn't generate non-ASCII characters so it
is safe for the python PCAP-generating script to assume that those
characters are garbage output (e.g. in initialization) and can be
ignored.

…-netif_hdr

sniffer: remove gnrc_netif header; read LQI

This is mainly a preparation step to make some arguments (namely
baudrate and the "serial/socket" argument) optional, to make it more
usable like the old `rftest2pcap` script for the econotag.

…gparse

sniffer: use argparse to parse script arguments

…udrate-optional

 sniffer: make baudrate optional

The KISS approach alternative to RIOT-OS#38 (also includes RIOT-OS#39, because...).
Disadvantage: we loose backwards compatibility for this tool.

…ript-decode

sniffer: script: ignore non-ASCII characters on input

…nn-type-from-context

sniffer: get connection type from string format

I was able to reduce stack usage by 2/3 on `samr21-xpro`. Additionally,
I removed the leading `0x` for the hexadecimal numbers. The parsing
script knows which numbers are hex (all of them) and they just waste
time both on the node and in the parsing script

…_openwsn

openwsn: remove deprecated application

…rate

sniffer: fix default baudrate in script

The script was moved from the main RIOT repository to the sniffer
application's directory in 08b173b. This fixes the README of this
application to reflect that.

The sniffer script was ported to an `argparse`-based approach for its
parameters in fb79b79, 5017bea, and 22516be. However, that change was
missing an update to the README. This fixes that.

sniffer: various documentation improvements

 sniffer: use fmt instead of printf

uncrustify: fix existing applications

Accessing and handling of network interfaces with gnrc_netif has changed
and needs adaption to compile and work again.

Currently only the at86rf2xx driver supports the required NETOPT to make
the spektrum scanner work.

…-scanner

spektrum scanner: adapt to new gnrc_netif calls

Adapt python script to comply with python coding conventions, i.e.
fixing error reported by flake8.

spektrum-scanner: fix plot_rssi.py script

This application allows to send (small) messages via CoAP to any
destination address. To chat locally you may use `ff02::1` to reach
neighbouring nodes, or chat directly using unicast addresses. The
application provides a distinct shell command `chat` but also brings
standard shell commands like `ifconfig` to show a nodes IP addresses.

coap-chat: a simple chat application using gCoAP

Make differences in ED level more visible.

Avoids a hard fault when using the latest RIOT master where raw mode
does not provide a netif header.

…xt-nullptr

sniffer: Check for missing netif header in dump_pkt

The RIOT submodule is intended to be fixed to lastest release, in this
initial state that is 2018.10. The idea is to make sure all applications
compile and run with that release and the submodule is later on updated
by the RIOT release manager as part of the release process.

add RIOT as submodule

CI: add travis config
