Hello, I am trying to compile the ranging example in my machine (Ubuntu 16.04) , but I am facing this issue:

alexandre@alexandre-ThinkPad-T420:~/contiki-uwb/examples/ranging$ make TARGET=dwm1001

I already could finalize MAKE commenting the #include "contiki-conf.h" in uart0.h, So I tryed to declare the entire route to the file #include "../../../platform/dwm1001/contiki-conf.h" n uart0.h but the problem remains.... Could you pls help me to verify this issue?

Hi,
I am a newcomer on uwb device and contiki system, so it's a little confuse after I success compiler the ranging example and write the .hex file to DWM1001, I don't know how to start the next step. Sorry it sound like a stupid question but i can't find the solution. Thanks for helping me.

Hi. I've been following your guides to run the rng application on my evb1000 board and I just cannot figure out why the printf fuctions are not working. Below is the compiling message and it does not print out anything at all after make login.

I tried adding "#define PRINTF(...) printf(VA_ARGS)" line into rng.c and Makefile but it don't work neither. So I compiled this test-serial project which the code is shown below and apparently it also doesnt work. Seems like serial communication is not working at all although compiling is done successfully. I would really appreciate it if there is any idea you can tell about this situation.

when i learning your file cir.c. Have error whit the code #include "contiki.h". I could't find this file. Could you please help?

Hello,

I cloned the contiki-uwb git, and the sub-module contiki, in the sub-module. So, in the submodule I started the Cooja simulator, in order to create a mote using dwm1001 port.

In Cooja I start a "New Simulation", "Create New Mote Type" and choose "Cooja Mote".

Then I tried to compile the ranging example to create this mote I got this error:

I also tried to change the make command as is suggested in README, make TARGET=dwm1001, but got another error:

I already set before the PATH for NRF_SDK in ~/.bashrc
export NRF52_SDK_ROOT=/home/alexandre/Downloads/nRF5_SDK_16

Is there any settings in COOJA that I need to change to refer to correct enviroment variable?

Could you guys please give me a hint how I can start to create a DW1001 mote?

Thanks a lot

After flashing the ranging example and resetting, initialization fails and the display shows "INIT FAILED" message. What is the cause?
