How to use the ZBoss zb_secur_set_tc_rejoin_enabled API Call

[WestCoastDaz]

I'm working with several Samsung SmartThings and I am wondering if a call to 

zb_secur_set_tc_rejoin_enabled(true)

will address this the issue of devices leaving the network insecuely https://www.samsung.com/sg/support/mobile-devices/overview-of-samsung-smartthings-secure-mode/

Hi,

The function zb_secur_set_tc_rejoin_enabled() specifies whether Trust Center Rejoin is allowed or not. When it's set to ZB_FALSE, devices attempting insecure rejoin will not be authorized, so it would be the same as Secure Mode ON in the link you attached, while if it's true then insecure rejoin is enabled. 

Best regards,

Marte

Thank you for the quick response.  Two follow up questions:

1. I'm assuming the default setting for this is ZB_FALSE, is that correct?
2. To use this API should it be called before the ZBoss stack is started?

Thanks,

Darren

Hi Darren,

1. Trust Center Rejoin is enabled by default, so set to ZB_TRUE.
2. You shouldn't need to call this API before the ZBOSS stack is started. Usually there's information in the documentation for the function if you need to do that.

Best regards,

Are you sure that Trust Center Rejoin is enabled by default.  I have some SmartThings sensors that use install codes that don't seem to rejoin after leaving the network.  They seem to require the the install code to be used again before allowing a rejoin.

Thanks,

Hi Darren,

When the devices leave the network, are they doing that with REJOIN=1?

It would be helpful to know whether the devices delete their network credentials or not.
