config ZigBee permit join interval and it's broadcast address

[$pider]

Hi

I'm using ZigBee light control coordinator example in "nRF5 SDK for Thread and Zigbee v3.1.0" on nRF52840 evaluation board.

when it will execute bdb_start_top_level_commissioning(ZB_BDB_NETWORK_STEERING) under ZB_BDB_SIGNAL_DEVICE_FIRST_START switch case, by default 180 seconds of permit join is started. So, how can I modify this default 180 seconds interval, as well as broadcasting address of permit join?

Hi,

I think you could use function zb_nlme_permit_joining_request().This function is used to allow permit joining requests for a given amount of time, and block it otherwise. I'm sorry, this function is not described in our documentation, but there is a brief description inside zboss_api_nwk.h and you could implement something like this:

void join_permit(zb_uint8_t param)
{
  zb_buf_t *buf = ZB_BUF_FROM_REF(param);
  zb_nlme_permit_joining_request_t *req_param = ZB_GET_BUF_PARAM(buf, zb_nlme_permit_joining_request_t);

  /* permit joining forever */
  req_param->permit_duration = 0xff; /* in seconds */


  zb_nlme_permit_joining_request(param);
}

Keep in mind that the default 180 seconds minimum permit join is specified in the BDB specification, so I am not sure how wise it will be to open the network for values lower than that.

I am not sure what you mean by broadcasting address of permit join? Could you explain yourself a bit more?

Best Regards,
