How to initialize zigbee network with persistent data?

Hi,

I have spend several days trying to initialize a network with persistent data. Meaning: Save the zigbee network settings and joined devices and load them again after a reboot/power loss.

Below the code I use to initialize it. But after that the devicelist is empty/stays empty. If I store it aswell and load that again I get the error that the deviceID is not found in the APS address map.

The flow of the code is:

  1. The network is initialized
  2. network is formed and device can join.
  3. device join and are added to the devicelist
  4. the persistnotify is called and stores data
  5. reboot: network is initialized and loads data with code below.
  6. Device are not joining and list stays empty...

apparently I miss something in the flow, but I cannot find this anywhere in the documentation. Really looking for some suggestions :)

I now also tried this with the QCLI, and also there it does not seem to work. Is this an issue with the QAPI an loading or do I just miss a step?

Steps - Device 1:

ZigBee Initialize
ZigBee Setextaddress 000000FFFE000001
Zigbee ZCL CreateEndpoint 1 4
Zigbee form 1 0 18
Zigbee permitjoin 255

Device2:

ZigBee Initialize
ZigBee Setextaddress 000000FFFE000002
Zigbee ZCL CreateEndpoint 1 5
Zigbee Join 1 1

Response device 2:

> ZigBee: Join confirm:

> ZigBee:   Status:        0

> ZigBee:   NwkAddress:    0xBE9E

> ZigBee:   ExtendedPanId: 0000000000000007

> ZigBee:   Channel:       18

 

Response device 1:

> ZigBee\ZDP: Device Annce:

> ZigBee\ZDP:   ExtendedAddress: 000000FFFE000002

> ZigBee\ZDP:   NetworkAddress:  0xBE9E

> ZigBee\ZDP:   Capability:      0x8E

 

all seems well... I add both addresses both the address and extended addresses and the panid to the devicelist.

Device 1:

Zigbee AddDevice 3 000000FFFE000002 1

Zigbee AddDevice 2 0xBE9E 1

Device 2:

zigbee adddevice 3 0000000000000007 1

Now I can control the device for instance with

Zigbee levelcontrol movetolevel 1 1 1 100 10

Then shutdown one of the zigbee stacks and re-initialize it (example here is the co-ordinator):

Zigbee shutdown

Zigbee initialize 1

Zigbee ZCL CreateEndpoint 1 4

Zigbee form 1 0 18

 

But the device will never connect back. I only shutdown either the coordinator or the other device.

I tried multiple things, but most of the time I get the following error:

#define QAPI_ZB_ERR_APS_NO_SHORT_ADDRESS                 (QAPI_ZB_ERR(169)) /**< APS status indicating a transmission using a short address failed because a                                                                                 short address for the device was not found in the address map. */

Kindly initialize with option 1 (ZigBee Initialize 1)  to use persist data.Device 1:

ZigBee Initialize 1
ZigBee Setextaddress 000000FFFE000001
Zigbee ZCL CreateEndpoint 1 4
Zigbee form 1 0 18
Zigbee permitjoin 255

Device2:
ZigBee Initialize 1
ZigBee Setextaddress 000000FFFE000002
Zigbee ZCL CreateEndpoint 1 5
Zigbee Join 1 1
 
Device 1:
Zigbee AddDevice 3 000000FFFE000002  1
Zigbee levelcontrol movetolevel 1 1 1 100 10

 

If End Device is restarted, initialize as below and control the device: // SHUTDOWN
ZigBee Initialize 1
Zigbee ZCL CreateEndpoint 1 5

 

If CoOrdinator is restarted, initialize as below and contro EndDevice: // SHUTDOWN
Zigbee Initialize 1
Zigbee ZCL CreateEndpoint 1 4
Zigbee AddDevice 3 000000FFFE000002  1
Zigbee levelcontrol movetolevel 1 1 1 100 10
