(CC2562P) TC_DEV_IND with PermitJoin with value 0 seconds.

Luca Vetri

Hi,

I would like to know if I run a ZDO_PERMIT_JOIN command with value 0 seconds do I still get the TC_DEV_IND packets or I'm supposed to not receive anything from the ZED?

BR,

You shouldn't receive TC_DEV_IND from a new device if you don't enable permit join.

Hi Luca,

If permit join is disabled on the ZC then there should not be any ZDO_TC_DEV_IND messages as the Trust Center should not allow a device to join the network. This message will only occur on a coordinator/trust center device.

Ryan

Pretty Interesting. I keep getting them although permit join timeout is set to zero.

I would suggest you to use sniffer to check what exactly happens over the air.

APP_CNF_BDB_START_COMMISSIONING will also reset the BDBC_MIN_COMMISSIONING_TIME which affects the permit join duration.

Any way to fix this? so i can close the network with permit join value:0 seconds

Yes, you can close network by set permit join time as 0.

I'm thinking a workaround regarding what Ryan said. I believe the network doesn't close due to some external influence.

When a new device joins the network, it will typically broadcast a Management Permit Joining Request which will restart the permit join timer. These can be monitored with zstackmsg_CmdIDs_DEV_PERMIT_JOIN_IND from the application. As YK mentioned, manually setting the permit join time to zero on the ZNP/ZC will prevent more devices from joining the network.

Ryan
