Rejoining Network

Abhishek Trivedi
Prodigy 170 points

Hi,

Once sending the data from the end device to the parent I am clearing the NV Storage in the end device by 

NLME_InitNV();
NLME_SetDefaultNV();

 Once I clear the NV ,it is not able to scan for any parents , I think it needs to get connected back to the network.

Now I want that the end device should search for all available PANs, and connect to one as it does when it is first turned on. Can anyone tell me how do I do that?

I'd really appreciate any help.

Thanks.

    You should not do what you are attempting - back out all of that code. Instead, you should send the ZED a leave request (either over the air from another device, like its parent, or from within the device from your Application code) and set the parameter in your request to initiate a new network join after leaving.

    /*********************************************************************
     * @fn          ZDP_MgmtLeaveReq
     *
     * @brief       This builds and send a Mgmt_Leave_req message.
     *
     * @param       dstAddr - destination address of the message
     *              IEEEAddr - IEEE adddress of device that is removed
     *              RemoveChildren - set to 1 to remove the children of the
     *                                device as well. 0 otherwise.
     *              Rejoin - set to 1 if the removed device should rejoin
                             afterwards. 0 otherwise.
     *
     * @return      afStatus_t
     */
    afStatus_t ZDP_MgmtLeaveReq( zAddrType_t *dstAddr, uint8 *IEEEAddr, uint8 RemoveChildren,
                     uint8 Rejoin, uint8 SecurityEnable )

    Dears,

    In my program, I use "zgWriteStartupOptions(ZG_STARTUP_SET, ZCD_STARTOPT_DEFAULT_NETWORK_STATE)" to clean up NV and do SystemReset() after that. You can have a try.
