hi all,
can anyone teach me how to start microcoap-server example.....

if i am running on native as per read me file i'm getting the following result..i dont know after what to do? i also installed copper plugin and radvd,when i'm trying to ping in firefox it showing network unreachable..

Waiting for incoming UDP packet...

Sometimes when receiving many frames in a short period of time, the UART speed is too low to be able to capture every frame. The current format of the sniffer output is very verbose and the data is hex encoded in ascii, so every sniffed byte will use three bytes on the UART.
Changing the format of the UART output into something like SLIP encapsulated 802.15.4 frames would significantly reduce the risk of lost frames.

This is an example output from the current version of the sniffer, the frame contains a 6lowpan compressed ICMPv6 echo request packet with the destination address ff02::1

rftest-rx --- len 0000001F lqi 79 rx_time 00000000025A4D96
41 D8 D0 23 00 FF FF 4E 6E B7 36 29 53 14 23 7A 3B 3A 01 80 00 C1 F4 00 53 00 03 53 53 53 53

The LQI and RX timestamp could be appended/prepended to the frame data to preserve the same functionality.

This change would possibly affect the shell functionality in the sniffer, the terminal program on the PC side might not handle raw binary data well, so the sniffer would need to be used together with the sniffer script to handle demuxing the binary frames from the shell text.

The instructions on how to set up the sniffer are outdated.
I didn't look into details yet but the way how parameters need to be provided is clearly different.

According to @haukepetersen microcoap has issues.

The RIOT submodule currently points to the almost 2 year old 2020.07 release. One of the future releases should fix this (and maybe also fix the CI / automation into the release manager script in the process).

Currently the travis configuration is broken. flake8 does not seem to work with the Python version they install.

currently, the openwsn application does not build, as the openwsn package is outdated?!

While trying to move away from our old econotag-based sniffer setup, I noticed that RIOTs sniffer seemed to drop some packets. I generated traffic on a RaspberryPi with Openlabs-Module using the following command:

# ping -s 100 -c1 ff02::1%lowpan0

This requires 6lowpan to use fragmentation, resulting in two succesive IEEE 802.15.4 frames being transmitted.

While the econotag correctly receives both, the sniffer app on a pba-d-01-kw2x only receives the first frame. I guess this is some kind of race condition. How would I go about debugging this?

E.g.

$ BOARD=samr21-xpro make flash
2015-03-27 20:39:53,328 - INFO # > nc ff02::1 1234 test
2015-03-27 20:39:53,329 - INFO #
2015-03-27 20:39:53,333 - INFO # Trying to send 5 bytes to ff02::1:1234
[board never comes back]

Stepping through the code has led my to thread_yield_higher, where the board appears to stop responding, but I'm not sure whether this is due to my non-existant gdb skills or if its related to the actual problem :D

PS: This does not seem to be related to UDP on the SAM R21 in general, since sending UDP packets with pretty much the same code works when taken out of the sixlowapp example. Also, the UDP server seems to work, as UDP packets sent from another app (i.e. not sixlowapp) can be received by the sixlowapp UDP server.

hi all,
when i running make for microcoap application getting the following error.if anybody knows share it will be useful for me.. thanks in advance......
