@rain rain,  I'd like to make some clarification here:

Firstly,  for NCP based on uart, we have two projects. One is based on hardware flow control, which is ncp-uart-hw. The other one is software flow control, which is ncp-uart-sw.  The use hardware flow control on UART, you will need four pins, Tx/Rx/CTS/RTS. To use software flow control, you just need two pins, Tx/Rx.  

If you use software flow control, you need to add "-f x" option to start the host project.

All our starter kit are based on hardware flow control.

Secondly, if you meet some problems, the recommended way to narrow down the issue is to use the pre-built ncp images on a starter kit. (Normally they can be found at C:\SiliconLabs\SimplicityStudio\v4\developer\sdks\gecko_sdk_suite\v2.6\protocol\zigbee\ncp-images).

If you can start the host with the starter kit,  it means the host is running OK. Then you can start the check the ncp side.

Thanks,

Jim

Hi Nguyễn Cao Bái,  the web UI of the gateway is not maintained any more. You can still find the source code of the UI project on github https://github.com/SiliconLabs/gateway-management-ui

For the issue about Simplicity Studio, please gather some debug info by "Help"-->"Report a bug"-->"Export Simplicity Studio log files", and then create a ticket at our support portal.

please refer to below KBA about the end device and le me know if you have any further questions.

I can't reproduce this issue with our GPD sample and Z3LightGPComboSOC example, could you try to use our GDP sample for verifyng this issue?

Best Regards,

Hi Nguyen,

After getting access to the Mesh stack, you can refer to QSG106: Getting Started with EmberZNet PRO for project examples.
