Question about using Install Code

[Subin Chen]

Hi Sir or Madam,

I tested examples\zigbee\light_control demo recently and I want to test install code function based on this example, the first step is I add install code in coordinator, then I power up coordinator and bulb(without install code function), and I found the bulb still can join the coordinator, does this means the install code function still can't work? If I want to use install code to join the netwrok that coordinator created what else I need to do? Thanks for your help!

if (zb_secur_ic_add(dut_ieee_addr1, ZB_IC_TYPE_128, install_code) != RET_OK){
}
zb_set_installcode_policy(ZB_TRUE);

Hello,

What SDK version are you using?

So where do you call this, and what does zb_secur_ic_add() return?

Please be aware that your check:

if (zb_secur_ic_add(dut_ieee_addr, ZB_IC_TYPE_128, install_code) != RET_OK)
{
    // you are not doing anything here.
}
zb_set_installcode_policy(ZB_TRUE);

BR,
Edvin

Hi Edvin,

Sorry for my misunderstanding. In fact the router is not join success, and the failure I found it is caused by the order of IEEE Address which I set on Coordinator is not correct.

Thanks!

I already checked the return value of add is RET_OK. Thanks.

/** Start Zigbee Stack. */
zb_err_code = zboss_start_no_autostart();
ZB_ERROR_CHECK(zb_err_code);

if (zb_secur_ic_add(dut_ieee_addr1, ZB_IC_TYPE_128, install_code) != RET_OK){
}
/* Set device installcode policy */
zb_set_installcode_policy(ZB_TRUE);

 You may mean to say that you have already checked while debugging, but this snippet doesn't check the return value of zb_secur_ic_add(), just in case you think this snippet checks, and your application is supposed to handle the exception if one occurs.

This is because the {} brackets are empty. Just like this will print "a is equal to b":

uint8_t a = 1;
uint8_t b = 2;

if (a == b)     //check if a == b
{
    
}

NRF_LOG_INFO("a is equal to b");

I'm glad to hear that you found out the issue

Best regards,

Edvin
