Yes, the ModemManager was the issue, it was still running under my nose, I was sure it was disabled and stopped! Thank you!
I am still having a "Permission denied: '/dev/ttyACM0'" error when the dongle switches to DFU so I need to run the command twice. I'll check udev config again. Thanks!

Hi Everyone, I'm trying to intercept all the packets that a node overhear, while awake, I know this is somewhere around the MAC files, but looking at CSMA.c files and the framer files, I couldn't pinpoint where exactly, it would really help if someone could guide me with this. I want to simulate it using Cooja. I know it may look straight forward, but I have little experience dealing with MAC. Also, my simulation script runner suddenly stopped working, in Cooja, I keep getting this error "construction error for tool of class: org.contikios.cooja.plugins.ScriptRunner". Any help would be appreciated. Thank you
PT_BEGIN(&state->pt);
CHECK_RESULT(bignum_exp_mod_start(e,1,m,1,b,1 ,&state->rv,state->process));
PT_WAIT_UNTIL(&state->pt, pka_check_status());
CHECK_RESULT(bignum_exp_mod_get_result(l_result, 1, state->rv));
PT_END(&state->pt);
CHECK_RESULT(bignum_exp_mod_start(e,1,m,1,b,1 ,&state->rv,state->process));
PT_WAIT_UNTIL(&state->pt, pka_check_status());
CHECK_RESULT(bignum_exp_mod_get_result(l_result, 1, state->rv));
PT_END(&state->pt);
But i always get PKA_STATUS_BUF_UNDERFLOW error. I checked in the bignum_exp_mod_get_result function and i see that the length of the result is always -3.
Someone know if exist any issue with this function?
by default, it drops frames not for the node
you can modify this bit. Or create your own MAC layer if you want more extensive changes
for Cooja, I find it best to use Docker - it always works there, when the official Contiki-NG docker image is used
i want to ask is any new version coming after the release of contiki-3.0
:point_up: November 25, 2020, 7:29 PM Since Contiki-NG does not work off the shelf with 6lbr so will i not be possible to push the data to ubidots ??
Now the problem is Mqtt-client isn't connecting to the 6lbr router
Are you stumbling anywhere?
I use a cc1352p1 launchpad.
But what you describe tells me that fundametal communication with the flash works
erase, read, write something, read it out
perhaps you are spending too much time inside your function without refreshing the watchdog, and it barks at you
Just created PR #1464 that provides preliminary support for the TI LPSTK sensortag in the Simplelink platform. It needs massaging to conform to contiki-ng best practices and I don't feel educated enough to complete the needed modifications. I know @g-oikonomou has specific ideas about how what I did in the modified hdc-1000-sensor.c is not up to snuff. There may be other needed changes but I want to remove me as the expected maker of these changes.
Anyone using Mac OS Big Sur yet? I am using Mac OS Catalina, and I can run the RPL Border Router natively on my Mac through the tunslip mechanism, after I use Homebrew to install tuntap. But apparently Big Sur is doing away with 3rd Party kernel extensions (kexts) and tuntap relies on a legacy kext being available. Anyone with experience with contiki-ng and a Mac running Big Sur, specifically around running target Native applications? Or using tunslip natively on a Mac using Big Sur?
@g-oikonomou Thanks, I would like to know if I am able to upgrade to Big Sur and not be negatively impacted. I am using the native RPL border router on my Mac with a SLIP radio cc1352r launchpad and a LPSTK sensortag running mqtt-client. But tunslip6 required me to deploy tuntap before it would work.

Hi All,
I was wondering if there is an example project that shows how to use SPI instead of UART?
I want to connect an ESP32 and communicate with SPI with a CC1310 flashed with RPL-Border. I can get it to work with UART, but I can't find an example to make it work in SPI
Thank you!
hello, i'm trying ubidots demo and i am using cetic-6lbr router. i have created a blank device and also created two variables under the device(temperature and humidity). i have enabled CONTIKI_WITH_IPV6=1 and ubidots address as ::ffff:a937:3df3. and also i have given variable ID's and ubidots token in project-conf.h file.
