Packet structure send and receive via uart zigbee NCP

[ashegheparyshun]

Hi,

I'm trying to take advantage of nRF52840 as Zigbee NCP in communicate with a host microcontroller via UART. My problem is I don't know what I have to send and what will get.

For example, Texas Instruments has a graphic user interface application for PC called ZTool, using this application you can communicate with for example cc26x2 launchpad over UART and send network formation command, and receive the result. It also has a document about it's packet structure, for example, there is a start byte followed by command type, command, etc.

I'm looking for this packet structure.

Hi,

Unfortunately, there is no documentation of the packet structure or commands for the NCP available publicly. You need to use the ZBOSS NCP Host package to create the application to communicate with the NCP SoC.

Best regards,

According to our developers, it should be possible to build the NCP Host package for any Linux Host MCU. 

Do you have a specific MCU in mind that you want to use?

[ashegheparyshun]

Yes, ESP32 from Espressif.

Any update?

As Zephyr is a Linux based operating system, can I use NCP library if I run Zephyr on ESP32?

Hi,

We do not have any support for building for ESP32, but you can port the package to your desired platform yourself. You will need to re-implement some part of OSIF (serial port access, logging subsystem, mechanism to restart the process etc) for your platform.

Zephyr is not a Linux based operating system, it is an RTOS and it does not use any code from the Linux kernel. It inherits the configuration system (Kconfig and Devicetree) from Linux, but this is implemented in Python for portability to non-UNIX platforms.

Best regards,
