z-Stack restore factory setting

Hi Felix,

I am not fully understand what exactly you mean by "factory settings".

Can you please describe in a more detailed way, what is exactly you

are trying to achieve here?

Br,

Hi,

By  "factory settings" I mean the following:

I have a device which is working in network 1.

Now I want to join this device to network 2.

So the device has to "forget" network 1 in order to join network 2.

After the "reset" the device should be in the same state as after programming (with "Erase Flash" on, except user defined NV variables) without reprogramming.

I hope this is clear enouth?!

Thanks,

Felix

Hi Felix,

Yes, this clarifies a few things.

I have one more question, how exactly the end device knows (what is the criteria)

that at this moment it should be trying to connect to network 2, or to network 1?

By the way, network 1 differs from network 2 by PAN_ID, by ZigBee Channel, or by both?

Hi,

the reset is initialized by a button press sequence done by the user.

After the sequence the device should search for networks and connect to the strongest (this can be network 1 or any other network, exactly the same way as it does during the first boot).

The difference can be pan ID, Channel, extended pan ID or non of the listed items (When there is no other network it should join the "original" network).

Thanks

Hi,

Ok, let's say that the user has pressed the right sequence and now let's assume for

a moment that somehow you've managed to store your application's current state

(so it could be restored later).

If the device's FW was precompiled with the following configurations:

1. -DDEFAULT_CHANLIST=0x00000800  // 11 - 0x0B
2. -DZDAPP_CONFIG_PAN_ID=0xFFFF
3. NV_INIT and NV_RESTORE options are OFF
4. No HOLD_AUTO_START option initiated

Calling SystemReset(); will reset the device (hard reset). After this type of reset the device

will scan for available network.

Is that what you are trying to do, or am I mistaken somewhere?

Br,

Hi,

I forgot to mention that I'm using NV_INIT and NV_RESTORE - sorry about that.

ad 1) yes

ad 2) yes

ad 3) no

ad 4) yes

NV_INIT and NV_RESTORE are turned on, because normaly when a power cycle is done the device should rejoin its network.

Just image a situation in the field: (how it should work)

My device is a Home Automation Mains Power Outlet.

It has been working in its network for a longer period of time, survived a few balckouts, ...

Now I wan't to join this device into a new network.

I press the "magic sequence" and the device does a reset into a state where it is ready to join a new network.

Device joins the found network.

Everyone is happy :)

Thanks

Felix

Hi Felix,

Ok, so you've pressed the "magic sequence" and now your device

restored to "factory setting", while the PAN_ID configured to 0xFFFF.

What can possibly prevent from this device to join the network it has been

associated with prior the "magic sequence" was entered?

Br,

Hi Felix,

You are correct, except one thing, you must set ZCD_STARTOPT_DEFAULT_NETWORK_STATE

before you doing the SystemSoftReset() (or other reboot).

Br,

Igor

Hi,

thank you, I will try it on friday.

Felix

Hi,

this worked for me. I set "ZCD_STARTOPT_DEFAULT_NETWORK_STATE" before resetting the device and afterwards it joins a new network.

Big thanks

Felix

Hi,

 

please corret me if I'm wrong:

I have to add "HOLD_AUTO_START" to my compile options and initialise network start on my own by calling "ZDOInitDevice()" (e.g. from "xxx_Init()" function). To let the device join a new network I do a reboot (SystemSoftReset()) and set "ZCD_STARTOPT_DEFAULT_NETWORK_STATE" before calling "ZDOInitDevice()"?

 

Thanks

Felix
