Having the definitions sit in the `net/gnrc/sixlowpan/frag.h` header
does not make much sense, when using Selective Fragment Forwarding
(and the fragmentation buffer already includes a
`net/gnrc/sixlowpan/frag/stats.h` header), so they are moved to their
own header. Since with this change it makes more sense to have the
statistics stored in their own sub-module, the pseudo-module is also
actualized.
Previously `ifconfig` would only know link-local addresses
(printed as 'local') and everything else would be 'global'.
This is wrong for site-local and unique local addresses which were
also denoted as global.
So use the already existing helper functions to determine the correct
type of IPv6 address when printing.
Replaces the special heap command approach of the lpc_common module with a more general heap command approach. Module lpc_common was already removed with PR #2118. PR #2118 integrated cpu/lpc_common code in cpu/lpc2387. With PR #3530 special heap handling for cpu/lpc2387 was replaced by newlib memory management which uses _sbrk_r to allocate chunks from the heap. _sbrk_r uses _sheap and _eheap symbols that are defined in lpc2387.ld and can be used together with mallinfo function for heap statistics.
- Add SEMTECH_LORAMAC_ALREADY_JOINED ret code for semtech_loramac_join
- Add SEMTECH_LORAMAC_TX_CNF_FAILED ret code for semtech_loramac_send
- Update shell commands to notify when no ACK is received on cnf tx
Add a trivial shell program that scans for all slaves on an I2C bus by iterating
all of the possible 127 I2C addresses and checking for the ACK of the device.
I was looking for a quick way to gauge the link quality between two nodes,
so I added the rssi to the output of the ping6 command.
Maybe this is generally useful to have.
Loosely based on [the original ping] and [netutil]'s ping
New features (compared to old RIOT version):
- non-positional parameters
- Better duplicate detection (addresses #9387)
- Better asynchronous behavior
- Potential for future move to `sock_ip`
- (Optional) DNS-support
- Multithreading-safe (in case shell-command handler gets called
from multiple threads)

When IPv6 is enabled, the MTU is given. So users(*) sending IPv6 packets can
easily figure out what the supported maximum protocol unit is.
However, when IPv6 is disabled and a user wants to send layer 2 frames directly,
no information about the maximum PDU is available using the shell.
When 6LoWPAN is used, a user may be interested in the layer 2 PDU as well in
order to avoid layer 2 fragmentation.
This PR adds the L2-PDU info to the output of the ifconfig shell command, which
is printed regardless of the use of IPv6.
(*): Here "users" refers to human beings interacting with the shell.
Applications can get the maximum PDU of each layer more easily using
gnrc_netapi_get() with NETOPT_MAX_PACKET_SIZE instead of using a shell command.
Currently an interface's existence is not checked when it is supplied
by the user with the `nib` command. This can lead to assertion errors
as soon as the generated entry tries to resolve an address or route
generated with that command and the network interface not being found.
sc_rtc.c should only be compiled if periph_rtc module is actually used.
In practice there was not linking error when PERIPH_OPTIONAL|_REQUIRED
was not set as shell_commands hides calling the functions with
'#ifdef MODULE_PERIPH_RTC'.
This updates the ccn-lite package version which brings in the
latest upstream fixes for some compiler issues found on macOS
with clang and newer GCC versions.
A minor adaption of the RIOT shell commands is also included.
When compiled for `hifive1` board with `gcc-7.2.0` this warning was raised:
'ret' may be used uninitialized in this function [-Werror=maybe-uninitialized]
- Use RIOT's GPIO interface to access the sensor to increase portability
- Changed API to allow more than one sensor per board
- Added `sht1x_params.h` that specifies how the sensors is connected - each
board can overwrite default settings by #defining SHT1X_PARAM_CLK and
SHT1X_PARAM_DATA
- Changed arithmetic to use integer calculations only instead of floating point
arithmetic
- Added support for checking the CRC sum
- Allow optional skipping of the CRC check to speed up measuring
- Added support for advanced features like reducing the resolution and skipping
calibration to speed up measuring
- Allow specifying the supply voltage of sensor which heavily influences the
temperature result (and use that information to calculate the correct
temperature)
- Reset sensor on initialization to bring it in a well known state
- Support for the obscure heater feature. (Can be useful to check the
temperature sensor?)
- Updated old SHT11 shell commands to the new driver interface, thus allowing
more than one SHT10/11/15 sensor to be used
- Added new shell command to allow full configuration of all attached SHT1x
sensors
- Removed old command for setting the SHT11 temperature offset, as this feature
is implemented in the new configuration command
The sensor family SHT10, SHT11 and SHT15 only differ in their accuracy (as in
calibration, not as in resolution). Thus, the same driver can be used for all.
The new driver name better reflects this fact.
I'm using something like this command for a while now for debugging
GNRC. Usually, I just patch it into the application I'm using it with,
but I think there is a benefit to also provide it to RIOT upstream
properly.
