White List for Passive BLE Observer

[PaDo_1228851]

Hi.  I want a passive BLE Observer to accept advertising packets from one and only one designated BLE Peripheral.  Is this possible?  I've studied the Cypress BLE_Whitelist project on GitHub but I am still having trouble.  I believe all I need to do is, in my Observer's main.c, pass my designated Peripheral's 6 byte public address by calling CyBle_GapAddDeviceToWhiteList().  Then if my Observer is set to passive scanning and whitelist only filtering, it should work, correct?

   

The problem I am having is correctly getting the designated Peripheral's 6 byte address into the bdAddr[] of my CYBLE_GAP_BD_ADDR_T struct.  Could you show me what that should look like?

   

Thanks much,

The address should be used as following:

   

    CYBLE_GAP_BD_ADDR_T bdAddr;
    
    bdAddr.bdAddr[0] = 0x01; /* LSB of 6 byte Address */
    bdAddr.bdAddr[1] = 0x02;
    bdAddr.bdAddr[2] = 0x03;
    bdAddr.bdAddr[3] = 0x04;
    bdAddr.bdAddr[4] = 0x05;
    bdAddr.bdAddr[5] = 0x06; /* MSB of 6 byte Address */
    
    bdAddr.type = 0;    /* public = 0, Random = 1 */
    
    CyBle_GapAddDeviceToWhiteList(&bdAddr);

Thanks roit.

   

I put the code below in my empty main.c file, just above the int main() loop:

   

************************************

   

#include<project.h>

   

#include<BLE_1_Stack.h>

   

CYBLE_GAP_BD_ADDR_T periph;  
    
    periph.bdAddr[0] = 0x01; /* LSB of 6 byte Address */
    periph.bdAddr[1] = 0x02;
    periph.bdAddr[2] = 0x03;
    periph.bdAddr[3] = 0x04;
    periph.bdAddr[4] = 0x05;
    periph.bdAddr[5] = 0x06; /* MSB of 6 byte Address */
    
    periph.type = 0;    /* public = 0, Random = 1 */
    
    CyBle_GapAddDeviceToWhiteList(&periph);

   

********************************************

   

All but the top line of code had syntax errors.

   

The lsb to msb lines had the same error message: unknown type name 'periph'

   

The periph.type line's error message was also: unknown type name 'periph'

   

The error on the line CyBle_GapAddDeviceToWhiteList(&periph);  was: type specifier missing, defaults to int

   

The same results obtained when I pasted in your code exactly as is: unknown type name 'bdAddr' on all lines but the top and bottom.

   

What have I left out?

   

Thanks.

What I mean is this line:

   

CYBLE_GAP_BD_ADDR_T periph;

   

had no error

   

Nor did "CYBLE_GAP_BD_ADDR_T bdAddr;"  when I pasted your code.
