cc2530znp network join after coordinator reset

Hi All !

What is the meaning of the TCSignificance byte in the ZDO_MGMT_PERMIT_JOIN_REQ (ZNP command) ?

The "Z-Stack Developer's Guide" says:

"10.3 Network access control

In a secure network, the trust center (coordinator) is informed when a device joins the network.

The coordinator has the option of allowing that device to remain on the network or denying

network access to that device.

The trust center may use any logic to determine if the device should be allowed into the

network or not. One option is for the trust center to only allow devices to join during

a brief time window. This may be possible, for example, if the trust center has a “push” button.

When the button is pressed, it could allow any device to join the network for a

brief time window. Otherwise all join requests would be rejected. A second possible scenario

would be to configure the trust center to accept (or reject) devices based on their

IEEE addresses.
This type of policy can be realized by modifying the ZDSecMgrDeviceValidate() function

 found in the "ZDSecMgr.c" module."

 How to accomplish this behaviour with the ZNP using the AF/ZDO interface ?

Ok, it was my fault. It seems that when starting the ZNP I need to explicitly tell ZCD_NV_STARTUP_OPTION to be 0x04 or 0x00. So not clearing the state and config is not enough.
