Hello,

All three examples (from the NCP "SDK") works out of the box. Note that these use channel 21 by default, while the Zigbee samples from NCS uses channel 16 by default.

To change the channel, please use channel mask (1l<<channel) (where channel is the channel number you want to use, e.g. channel mask (1l<<13) ).

The reeason you have build issues is the lack of a space character before the channel mask. It should be #define LIGHT_CONTROL_CHANNEL_MASK space (1l<<13). Without the whitespace character, it defines an empty macro that takes parameters inside the paranthesis.

I have seen that the customer had some issues determining what protocol that is used by the Host to communicate with the NCP. Please remember that we provide two .hex files for the nRF52833 board:

ncp_nrf52833_xxaa_uart.hex
ncp_nrf52833_xxaa_usb.hex

The first one uses UART which goes through the on-board Segger. You can determine which serial port your NCP board is assigned with by issuing the nrfjprog --com command. The second one uses native USB which requires an additional USB cable connected to the on-board nRF USB port.

Also note that NCP stores some information in it's flash memory. When testing different applications and connecting to different networks it may be necessary to erase the flash memory in between two runs.

Best regards,

Edvin

Sorry, Pranav. There isn't.

I'll ping the internal ticket.

Please note that there is Easter vacation season in Europe, so it may cause some delays in the answer from our Zigbee team (I am not sure how they are staffed during Easter).

I just wanted to know whether this Zigbee NCP example is tested? Or still in the development phase.

Because I have tried everything that suggested in this Zigbee: NCP — nRF Connect SDK 1.5.0 documentation (nordicsemi.com) link and my ticket still not getting any result.

It has been two weeks since I have followed this ticket but still not getting any positive result regarding the NCP sample example.

Also in the log file that I have provided

It says "Can't find PAN to join to! " what does that mean ? What PAN I required and where it located ?

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,

Hello Edvin,

Thank you for your quick reply. I tried what you suggested.

[quote userid="26071" url="~/f/nordic-q-a/72360/use-of-ncp-in-zigbee/300941#300941"]Ok, so you intend to run the light switch from the ubuntu machine then, correct?[/quote]

Correct.

[quote userid="26071" url="~/f/nordic-q-a/72360/use-of-ncp-in-zigbee/300941#300941"]

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).

[/quote]

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).

[quote userid="26071" url="~/f/nordic-q-a/72360/use-of-ncp-in-zigbee/300941#300941"]

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)

[/quote]

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.

devzone.nordicsemi.com/.../light_5F00_control.log

Can you please suggest what else (modification) required to test the NCP example?

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.

RE: Use of NCP in Zigbee

Edvin — Wed, 17 Mar 2021 15:16:38 GMT

I don't understand your NCP example issue. The NCP is a network co processor. What are you using it with? It needs an application CPU running an openthread application, and using the nRF NCP as the radio. What is running your application?

"I am running the light_control application and NCP connected to my Linux pc".

What is your linux pc doing then? Is it doing some openthread things? Or do you expect the NCP to create a folder that you can drag and drop applications into? (That is not a serious suggestion, but I try to figure out how you are trying to use the NCP example).

RE: Use of NCP in Zigbee

Edvin — Tue, 16 Mar 2021 20:20:32 GMT

With version 1.5.0, if I flash the unmodified light_bulb, light_switch and network_coordinator from the ncs\nrf\samples\zigbee folder, they all connect and I can control the light bulb using the light switch. LED3 and LED4 is on on the switch. If that is not the case in your test, can you please try to erase all boards, and compile and flash them. NB: LED4 on the light_switch doesn't turn on until you press button1 or 2 to turn on/off the light.

Regarding the BLE:

Does it work after the configurations? I don't know what to say. I can't guarantee that all examples are the exact same from version to version. There are probably some differences in main.c as well.

I see that in v1.4.2, CONFIG_BT_NUS is not set to y either, so bluetooth is not enabled by default. Is that what you claim it was doing, or do I misunderstand?

RE: Use of NCP in Zigbee

Hello Edvin,

Thank you for your reply. I tried what you suggested. It worked but In the light_switch board only LED 3: (On and solid when the device is connected to a Zigbee network.) is ON.

LED 4 i.e. (On and solid when the light switch has found a light bulb to control) is not glowing/OFF.

I am not able to control the light_bulb from boards as well as a mobile application

I am not able to understand what's wrong. In SDK v1.4.2 it's worked easily and seamlessly ( also setup part) without any additional steps.

Can you please help to resolve this issue?

I have attached some screenshots for proper understanding.

In the first step, I have imported/selected the light_switch example(under zigbee - light_switch)from SDK v1.4.2.

In this the path of the example is - C:/Users/Pranav/ncs/v1.4.2/nrf/samples/zigbee/light_switch/build_nrf52833dk_nrf52833

In the second step, I have followed the same for SDK v1.5.0.

In this the path of the example is

- C:/Users/Pranav/ncs/v1.5.0/nrf/samples/bluetooth/mesh/light_switch/build_nrf52833dk_nrf52833

I have also tried to enter the path manually in v1.5.0. But it also redirects to Bluetooth/mesh.

I also confirmed this issue with my colleague and the same issue occurred on his pc.

RE: Use of NCP in Zigbee

Edvin — Fri, 05 Mar 2021 12:56:32 GMT

Hello,

NCP stands for Network Co-Processor. Basically, it is used if you want to run the stack on another chip, and just use the nRF as the radio. So the Zigbee stack is split in two pieces. NCP and the rest. "The rest" is running on another chip, and sends commands to the NCP to tell it what to send over the air, and the NCP reports back with events from the radio to the application chip.

The NCP can either be a coordinator or a normal node (router or end device).

Best regards,

Edvin
