Switch Router and End-Device function after download the code

Alex Abraham

Other Parts Discussed in Thread: PMP, TIMAC

Hi,

we need to switch the Router and End-Device function AFTER we have already downloaded the code into chip, and wonder whether we can do as follow:

1、modify the code on Router, such as : add a devFlag, to indicate what the device type(router or end-device) shoule be now; also modify the code to du end-device function in router, or do router funcion in end-device;

2、coordinator send the commond over the air, the Router analysis the command and modify the devFlag, then swith between router and end-device.

TKS in advance!

Take a look at the ZNP sample application and how it is built to be able to act as either RFD or FFD with the BUILD_ALL_DEVICES build flag.

Take a look at the ZAP sample apps from the ZAP installer to see how to drive the ZNP "role change" behavior, and that is what you will imitate. Basically on command from your ZC, your device can just set the new device type, setup to do a new network join, and reset to effect the new device type and new network join:

#include "OSAL_Nv.h"

      uint8 startUp = ZCD_STARTOPT_DEFAULT_NETWORK_STATE;
      uint8 newDeviceType = ZG_DEVICETYPE_ROUTER;
      //uint8 newDeviceType = ZG_DEVICETYPE_ENDDEVICE;

(void)osal_nv_write(ZCD_NV_STARTUP_OPTION, 0, 1, &startUp);
(void)osal_nv_write(ZCD_NV_LOGICAL_TYPE, 0, 1, &newDeviceType);

SystemReset();

hi, harry:

I did what you suggested in ZNP->CC2530-Debug project, the device was restarted ,but still remain what type as it was, following is the screenshot:

Hi Alex,

Please try the below code and configuration in Generic Apps. It working for me. I can change the coordinator/router/end device

Compiler options --->preprocessor

HAL_UART=TRUE
xHAL_UART_ISR=FALSE
LCD_SUPPORTED
BUILD_ALL_DEVICES
HOLD_AUTO_START
NWK_AUTO_POLL

Linker--->Extra Option

   (void)osal_nv_read(MY_LOGICAL_ROLE_ITEM_ID, 0, 1, &NvFlg);
    if(NvFlg)
    {
      #if defined ( BUILD_ALL_DEVICES )
          // The "ATCommand" target is setup to have BUILD_ALL_DEVICES and HOLD_AUTO_START
          // we will start up a coordinator with 0 and Router with 1. Otherwise,

   }
