Zigbee network experiment

Zigbee network needs minimum a coordinator and a router. Since the Core2530/XCore2530 module has a built-in Bootloader in default setting, you can download the firmware to the module directly via the serial port.

Notes: In the Zigbee network experiment, you may need to apply two pieces of Core2530/XCore2530 modules, and two pieces of ZB502/ZB600 baseboards.

Roles in Zigbee network

1. Coordinator

  • Select a communication channel and a PAN ID to build a network;
  • Allow other routers and end devices to join this network;
  • Route the data in the network;
  • Must be kept power supplying, and must not enter the SLEEP mode;
  • Preserve data for the end devices entered SLEEP mode till them wake up and retrieve the data.

2. Router

  • Must join a Zigbee network before performing data transmission;
  • Allow other routers and end devices to join the network, after it joined one;
  • Route the data in the network upon joining the network;
  • Must be kept power supplying, and must not enter the SLEEP mode;
  • Preserve data for the end devices entered the SLEEP mode till them wake up and retrieve the data.

3. End Device

  • Must join a Zigbee network before performing data transmission;
  • Not allow other devices to join the network;
  • Transmit and receive data thought parent node, unable to route the data in the network;
  • Support battery power supply and SLEEP mode.

Bootloader

1. Introduction

The built-in Bootloader enable users to download the program to the module directly via a serial port without using the CC Debugger. However, the CC Debugger is required in the course of programming the Bootloader into the module. For more detailed information, please refer to the Section How to program Bootloader.

There are two different Bootloaders available for this module: bootloader.hex and bootloader_wait.hex.

For easier understanding, we call the module with the bootloader.hex as module A, and the module with the bootloader_wait.hex as module B in this document.

The module A will execute the valid program immediately, if any, in the Flash memory, after powered up. Otherwise, its LED1 will keep blinking indicating that there is no program in the Flash memory and you can download a new one via the serial port in this case.

For module B, its LED1 and LED2 will blink alternately, if there is any valid program stored in the Flash memory, after powered up. Now, if you press the button KEY2, the module B will execute the program immediately; and if you press the button KEY1, the module B will enter the Bootloader mode under which you can download a new program to the module B. In case of no key-press action within 40 seconds after powered up, the module B will execute the program in the Flash memory automatically. When there is no valid program in the Flash memory, its LED1 will keep blinking, and you can download a new one via the serial port in this case.

The module A with bootloader.hex is suitable for independent application, since it can run the program directly without any external key-press trigger. However, the module B with the bootloader_wait.hex should work with the baseboard ZB502/ZB600 for relative experiments and studies. By default, the bootloader_wait.hex is programmed to the module.

3. How to program Bootloader

  • Install the module to the baseboard, and connect the baseboard and the CC Debugger to your PC with the USB cables;
  • Power up the baseboard, and press the RESET key on the CC Debugger. If the communication is built up successfully, the indicator on the CC Debugger will light up and turn to green, indicating that it is ready to download new programs;
  • Open the SmartRF Studio7, and select the button Flash Programmer on the upper right of the software interface to open another window.

Firmware downloading

In this section, we will illustrate how to build a Zigbee network by applying two groups of Core2530 + ZB600, one works as a coordinator and the other one works as a router. For easier understanding, we call the coordinator as Group A and the router as Group B.

  • Connect the Group A and the Group B to your PC with the USB cables, respectively. And get their corresponding serial port numbers after powered up.
  • If the firmware has been installed to the Group A or/and the Group B, the LED1 and the LED2 on the Core2530 module(s) will blink alternately after resetting. Pressing the button KEY1 as soon as possible to enter the Bootloader mode,when the board is powered on.Then you will see the LED1 keep blinking. When there is no firmware in the Core2530 module(s), the LED1 will keep blinking after powered up, which means the Core2530 module(s) has entered the Bootloader mode directly and there is no need to press the button KEY1 again.

Core2530-XCore2530-User-Manual-7.jpg

  • Select the firmware file Coordinator.bin of the Group A in the Select File box and select the corresponding serial port in the Port Settings box,set the Baud rate:115200, Then, click the button Load Image to start downloading.
  • For the Group B, select the firmware file Router.bin. The file download method is the same as that of the Group A.
  • Start two serial debug assistants, and enter the serial port number of the Group A to one of the assistants and the port number of the Group B to the other one. Then, set the Baud rate: 38400, Data bit: 8 and Stop bit: 1;
  • Reset the Group A, you can see the LED1 and the LED2 on its Core2530 module blink alternately. Pressing the middle button of the joystick, you will see the message "Device starting ok" displayed in the window and the LED3 lights up, if the network is built up successfully.
  • Reset the Group B, you can see the LED1 and the LED2 on its Core2530 module blink alternately. Pressing the middle button of the joystick, you will see the message ""Device starting ok" displayed in the window and the LED3 lights up, if the Group B, severing as a router, has joined the network successfully. Now, the Zigbee network is running. (If no external antenna is applied to the Group B, it is recommended to place the antenna interface of the Group B close to the antenna interface of the Group A, in order to ensure the wireless network signal is strong enough.)

Notes:

1. The middle button of the joystick on the ZB600 is corresponding to the button KEY2 on the ZB502.

2. The power amplifier (PA) of Xcore2530 has occupied the Pins P1_1 and P1_4. Hence, the LED2 will not blinking after the Xcore2530 module reset, and the LED3 will keep OFF even if the network is built up successfully.

Networking communicaiton

The operations presented below can be done directly by UART serial communication, baud: 38400.
