If you only want advertising reports from your device address you need to put it in a whitelist and use it when you scan. There are several questions about whitelisting in here, have a look. If you get into trouble please add a new question and explain what you have done. If I answer your question please accept my answer by clicking the grey circle next to it.

I believe this is happening because you are getting too many advertising events, and staying in interrupt context 3 forever. The UART peripheral is configured to use the same interrupt priority, so it is not able to interrupt to tell that another character can be sent.

Possible solutions:

Stop scanning when you want to print something
Raise the interrupt priority of the UART from APP_IRQ_PRIORITY_LOW to APP_IRQ_PRIORITY_HIGH inside log_uart_init()
Try using Segger RTT instead of UART to print

Of course it will, it is before the if statement? How exactly is it printing your device address?

RE: central device

nordicbeginner — Thu, 12 Jan 2017 15:25:29 GMT

but if unwanted device is on then it will print unwanted device's address

RE: central device

nordicbeginner — Thu, 12 Jan 2017 15:24:31 GMT

yes. it will print my device address

So nothing is ever printed? Are you receiving any advertisments from your device if you turn off the unwanted device? Does

APPL_LOG("%02x%02x%02x%02x%02x%02x\r\n",
                             p_adv_report->peer_addr.addr[0],
                             p_adv_report->peer_addr.addr[1],
                             p_adv_report->peer_addr.addr[2],
                             p_adv_report->peer_addr.addr[3],
                             p_adv_report->peer_addr.addr[4],
                             p_adv_report->peer_addr.addr[5]
                             );

print your device address?

but my problem is that i want to print my devices data

RE: central device

nordicbeginner — Thu, 12 Jan 2017 15:06:51 GMT

yes nothing is printed

I'm sorry, but I still don't understand, if p=0x44, q =0x55, r = 0x66, s =0x77, t= 0x88 and u =0x99, (p == 0xD1 && q == 0x2A && r == 0xF7 && s==0x62 && t ==0x2f && u ==0xdb) should evaluate to false and nothing should be printed. Are you saying that it evaluates to true? If that is what you are saying I would appreciate if you could put a breakpoint on APPL_LOG("yes\r\n"); and use the debugger to show that p=0x44, q =0x55, r = 0x66, s =0x77, t= 0x88 and u =0x99. Take a screenshot.

my devices's mac address is 0xD1:0x2A:0xF7:0x62:0x2F:0xDB. if other device's mac address is 0x44:0x55:0x66:0x77:0x88:0x99 then i will get p=0x44, q =0x55, r = 0x66, s =0x77, t= 0x88 and u =0x99.

so this condition if( p == 0xD1 && q == 0x2A && r == 0xF7 && s==0x62 && t ==0x2f && u ==0xdb) will not be satisfied

What do you mean by getting the wrong value?

RE: central device

nordicbeginner — Thu, 12 Jan 2017 13:18:22 GMT

i have put condition if( p == 0xD1 && q == 0x2A && r == 0xF7 && s==0x62 && t ==0x2f && u ==0xdb) but if other device is in range then i am getting wrong value.

yes i want to printout content of advertisement when i get a match on address.

RE: central device

I'm having trouble understanding what the problem is here. Do you want to print out the content of the advertisment when you get a match on the address? And now it print outs even though there is no address match?
