Hello,
I am using nRF52833, nRF Connect SDK v1.5.0.
In v1.5.0 there is one new example i.e Zigbee NCP. ( Zigbee: NCP — nRF Connect SDK 1.5.0 documentation (nordicsemi.com)..)
In the above link, NCP and coordinator are both used for testing.
I'm not understanding what is the use of NCP. I am confused between the use of coordinator and NCP.
Can you please explain to me why and in which case NCP required?
What is the difference between NCP and coordinator?
Thank you,
Pranav.
Hello Edvin,
I have followed this link for Zigbee NCP Zigbee: NCP — nRF Connect SDK 1.5.0 documentation (nordicsemi.com)
The step I have followed -
1. The Zigbee network coordinator sample programmed on one separate device.
2.The Zigbee: Light bulb sample programmed on one separate device.
3. The NCP sample (under Zigbee) import on segger.
4. I have done the "Communication through USB" step by defining the -DCONF_FILE='prj_usb.conf'
in Tools - Options - nRF Connect - Additional Cmake Options
5. Then followed all the steps under Building and running. Also, follow the readme file under NCP Host for Zigbee.
After completing all the steps,
The network_coordinator board has LED3 and LED4 are solid ON and LED1 is blinking.
The Light_bulb has LED3 is solid ON and LED1 is blinking.
The NCP board has only a power light on i.e. LED5
Also, I have attached the screenshot of my NCP sample.
Where is this written? Can you please point me to the location of this readme file? It looks like you are pointing to the light_switch's readme.rst text, but mine doesn't say that.
In this link - Zigbee: NCP — nRF Connect SDK 1.5.0 documentation (nordicsemi.com) .
under "Testing" 6th point.
Am I doing something wrong here?
Can you please help me to resolve this issue?
Thank you,
Pranav
Hello Edvin,
Thank you for your quick reply. I tried what you suggested.
Ok, so you intend to run the light switch from the ubuntu machine then, correct?
Correct.
If you were to test the three examples without NCP:
light_bulb, netwoork_coordinator, light_switch and you set all the channels to 12, does that work? (just to make sure that the two other devices are working before you add the NCP).
These three standalone examples working fine for me. All three boards are connected and also I am able to control the light from both i.e. light_switch and BLE app (nRF ToolBox).
After you have programmed the board, do you switch the USB connector to the USB connector on the long side of the DK?
In the network coordinator and the light bulb, try adding this prj.conf configuration: CONFIG_ZIGBEE_CHANNEL=12
(doesn't have to be exactly 12. Anything from 11 to ...25? Don't remember the range, but 12 should work).
Then open light_control.h and change line 58: #define LIGHT_CONTROL_CHANNEL_MASK(11<<12)
As you suggested above I made all the changes.
while changing light_control.h line 58: #define LIGHT_CONTROL_CHANNEL_MASK(11<<12)
After modifying these file when I tried the "make" command I gives me an error
Also tried #define LIGHT_CONTROL_CHANNEL_MASK(1l<<12) instead of #define LIGHT_CONTROL_CHANNEL_MASK(11<<12) in light_control.h . Still facing same error
After this, I also tried with unmodified light_control.h (default) i.e #define LIGHT_CONTROL_CHANNEL_MASK (1l<<21) and
In the network coordinator and the light bulb, I have added this prj.conf configuration: CONFIG_ZIGBEE_CHANNEL=21
Also, switch the USB connector to the USB connector on the long side of the DK
The LED 3 turn on both boards i.e Coordinator and light bulb i.e
When LED 3 turns on, this development kit has become the Coordinator of the Zigbee network.
When LED 3 turns on, the light bulb has become a Router inside the network.
But the light control device not joining the Zigbee network, Also not sending the On/Off commands with a 15-sec period that toggle the LED 4 on the light bulb on and off.
In my terminal, I can't see any messages. I see some trace messages in light_control where does it suppose to appear?
I have also attached the light_control.log file. please find the attachment.
Can you please suggest what else (modification) required to test the NCP example?
Thank you,
Pranav.
Hello Pranav,
Unfortunately, I don't have an linux machine to run this on.
Can you confirm that you are using the USB port on the long edge of the DK,
When you try to run the application, and that you fed in the correct COM port? (may not be the same as when you programmed it).
If so, can you please try to set the default channel selection in the NCP sample, and use the nRF Sniffer for 802.15.4 and see whether you can see any packets being sent from the light controller? (For simplicity, turn off any of the other devices, the coordinator and the bulb). Check channel 21 using the sniffer and see if you can see any packets.
BR,
Edvin
