Remove a dead/disconnected device from ZigBee controller.

[Jimmy@zone]

Hi 

I have this code that works like a charm when the device is connected and I want it to leave the network.

But if the device is dead or disconnected and I want to  remove it from the controller it fails and I am

looking for the best way to handle this any thoughts ? 

    zb_buf_t *buf = ZB_BUF_FROM_REF(param);
    zb_zdo_mgmt_leave_param_t *req = NULL;
    zb_uint8_t tsn;

    LOG("send_leave 0x%04hX\n", dst_addr);

    req = ZB_GET_BUF_PARAM(buf, zb_zdo_mgmt_leave_param_t);

    ZB_MEMSET(req->device_address, 0, sizeof(zb_ieee_addr_t));
    req->remove_children = ZB_FALSE;
    req->rejoin = ZB_FALSE;
    req->dst_addr = dst_addr;
    tsn = zdo_mgmt_leave_req(param, leave_callback);

Hi,

Do you mean that you want to remove an end device device from the Zigbee coordinator? The device should be removed automatically from the router table automatically after a timeout period. Did you want the device to notify the network that it is leaving and should be removed before it leaves?

Best regards,
Jørgen

Yes I want to remove the device from the coordinator and that its not possible to rejoin.

What limits the device from coming back !? The statment would imply that I would need to do a new pairing if the device is disconnected for a long period. The pairing information must be stored some where. I look in the gc_addr_map when restarting to se what is paired. I can go manually in to the mapp and set that item to unused but I guess there is more to it.
