telink_zigbee_sdk-4.0.2.0 creating new project?

wes58

I have noticed that SDK has been updated and now supports B85 and TL721x series so I wanted to try it out. And it looks like the way the SDK works in Telink IoT Studio is different now. I started with File-Import and I selected only B85 and TL721x projects and I get this screen - which looks different from the previous SDK's  How do you create a new project/app based on, for example, existing configuration zigbee_sampleGW? For example I want to create project/app "ZGateway" Before I right click on a selected SDK and in properties I had configurations of all projects. I could create new and it worked. - Now, first I tried to right click on this sample project - zigbee_sampleGW_sdk (b85) - and in properties create new configuration which will be based on this sample. But I don't think this is the right way because I don't know where to put the folder with new source files? - Then I tried to create new project and then select "Referenced project" but it doesn't create the same folder structure as other projects have.  Could you please advise? <i class="pstatus"> 本帖最后由 wes58 于 2026-9-28 09:06 编辑 </i><br /> <br />

Here's how I do it，hope it helps you out. 1. Create a ZGateway folder under the build folder. 2. Copy the b85 folder (./build/zigbee_sampleGW/b85) into the ZGateway folder. 3. Change the name in the .project file (./build/ZGateway/b85/.project) to 'ZGateway'.     4. Put the vendor code under apps/zigbee/sampleGW. 5. Import the ZGateway project.     <i class="pstatus"> 本帖最后由 TL_YANGBIN 于 2026-9-28 16:58 编辑 </i><br /> <br />

Ok, so I can create a project based on your steps:  As you can see from the picture above, the problem is that my new project will use the same source files as sampleGW. This is because of all references in the `.project `file to `sampleGW`. I only show 2 in the picture below:  So, unless I change all of them to the location of the source files of my new project it is not going to work. Especially if you look at the picture from my previous zigbee SDK. I have many different projects (devices), which were based on a router project in the SDK - that's how you create new configuration in old SDK. The source code for each of them has to be in a separate folder.  So this is not going to work unless I change `.project` files for each of them. Is that the way to do it? Is there a better solution? **EDIT:** I changed all references to the sampleGW in the `.project` to ZGateway. I added folders with source code ZGateway and ZGateway_ext but nothing has changed. It is still showing source code for sampleGW. So this is not working. I probably would have to make changes in `.cproject `files as well. But I don't think that should be the way of creating new projects. <i class="pstatus"> 本帖最后由 wes58 于 2026-9-29 05:55 编辑 </i><br /> <br />

If you don't want to use sampleGW and sampleGW_ext, you could follow the steps below (instead of step 4 from before). 4. Put your vendor folder under ./apps. 5. Add the vendor directory to the workspace.    a. Right-click on the app and select 'new' -> 'folder'.    b. Select 'Linked Folder' and 'Variables' -> 'PROJECT_LOC'.    c. Complete the vendor path.     6. Use exclude to block unwanted files.     7. Select 'Properties' -> 'C/C++ Build' -> 'Settings' to change the project name or create a new configuration.

I will try it later. What I did this morning was this - following your previous steps: #1 Create a ZGateway folder under the build folder. #2 Copy the b85 folder (./build/zigbee\_sampleGW/b85) into the ZGateway folder. #3 Change the name in the .project file (./build/ZGateway/b85/.project) to 'ZGateway'. #3.1 Change all references to sampleGW and sampleGW_ext to ZGateway and ZGateway_ext in .project file #4 Create 2 folders with new source code in apps/zigbee/ZGateway and apps/zigbee_ble_concurrent/ZGateway_ext #5 Import the ZGateway project. #6 Change sampleGW to ZGateway:  #7 Change sampleGW and sampleGW_ext to ZGateway and ZGateway_ext:  And this worked. But I think your method will be better because I could group the same devices - for example I can create project "Routers_B85" and have all routers in one project area. I have to try it. Thanks for your help, again. Just one last question. In app_ble_cfg.h file there is the following line: `#if ZIGBEE_DIRECT_ENABLE    //only support for b91` Does it mean that Zigbee Direct is only supported by b91? What about TL7218? And I haven't seen in any file define for ZIGBEE_DIRECT_ENABLE -  `#define ZIGBEE_DIRECT_ENABLE  1` <i class="pstatus"> 本帖最后由 wes58 于 2026-9-29 12:48 编辑 </i><br /> <br />

The full code is as follows. It should mean that among B85 and B91, only B91 supports ZIGBEE_DIRECT_ENABLE. ``` #if defined(MCU_CORE_8258) || defined(MCU_CORE_B91) #if ZIGBEE_DIRECT_ENABLE    //only support for b91     .... #else     .... #endif #elif defined(MCU_CORE_TL721X) #if ZIGBEE_DIRECT_ENABLE     .... #else     .... #endif #endif ``` The ZIGBEE_DIRECT_ENABLE is defined in the preprocessor.

Thanks for this information. I didn't read the code carefully. Because now I realise that it means that it supports b91 but not 8258 series. <div class="quote"><blockquote><font size="2"><a href="https://forum.telink-semi.cn/forum.php?mod=redirect&goto=findpost&pid=102987&ptid=98925" target="_blank"><font color="#999999">TL_YANGBIN 发表于 2026-9-29 14:12</font></a></font><br /> The full code is as follows.

Alright, have a good day. <img src="static/image/smiley/default/smile.gif" smilieid="1" border="0" alt="" />

Thank you very much for your help but after spending 2 days on the new zigbee SDK I came to the conclussion that I have to stay with old zigbee SDK and zigbee ble concurrent SDK. Here is the reason for this: **Zigbee devices** After looking in drv_nv.h file I realized that I can't use my existing devices based on TLSR8258 because there is no support for 512k flash, although the size of the firmware is enough for this. **Zigbee Ble concurent devices** When I started to work with TL7218 I managed to convert my Gateway project from TLSR8258 (1M flash) to TL7218. I also copied (cloned) from TLSR8258 flash to TL7218 all the information about my Zigbee devices that I have on my network. And everything works fine. Now I noticed that in the new SDK (4.0.2.0) in drv_nv.h, memory mapping has changed so all the information about zigbee network that I have on TL7218 will be in different flash address. Especially that I also had to change it for 2M flash in TL7218.  I am not sure why this change was necessary or what else has changeg that would affect information about devices on my network. I like the idea that zigbee stack will be the same for both Zigbee and Zigbee Ble concurent, but for now I will leave everything as I had it for the last couple of years. Thanks for your support.

Early Zigbee and Zigbee BLE were independent of each other, without a unified flash memory layout. So, starting from V4.x, the two SDKs were combined to share the same flash layout, which makes it easier to develop and upgrade future products. Regarding the TL7218 issue with V4.0.2.0 that you mentioned, it can actually be fixed by slightly modifying the NV_BASE_ADDRESS_ZB and NV_BASE_ADDRESS_BLE addresses. ``` /************************************************************************ * Flash address of NV module. */ #define NV_BASE_ADDRESS_ZB              0xE0000 //(FACTORY_CFG_BASE_ADD - 0x18000) #define NV_BASE_ADDRESS_BLE             0xF7000 //(FACTORY_CFG_BASE_ADD - 0x1A000) ```
