Flashing the BD address in OTP - DA14531

Question

Dear Team, 
 We are using DA14531 soc for our application. I have used "default_app_generate_unique_static_random_addr()" to generate the unique address for each device. 
 In this I want to flash this unique address into the OTP memory at this address 0x07F87FD4. 
 I am using smart snippets cli for programming. After flashing i want to verify the BD address in the OTP and the address my device advertise are same. 
 How to read the particular address from the OTP using cli? and how to flash the BD address in OTP. 
 Kindly help me to solve this issue.

Hi TDC, 
 Thank you for posting your questions online. 
 Please refer to this tutorial for OTP and CLI:

Dear TDC, Thank you for the reply. 
 TDC said: Is there any other alternative way to get the BD address of the device, without scanning using mobiles. 
 On the following callback function declare a custom callback function that will call the default_app_generate_static_random_addr callback and then just print out the BDA via the bd_addr struct. //on user_callback_config.h file
 .app_on_generate_static_random_addr = default_app_generate_static_random_addr,
 
//implementation of the default callback functions can be found on app_default_handlers.c file

void default_app_generate_static_random_addr(struct bd_addr *addr)
{
 // Check if the static random address is already generated.
 // If it is already generated the two MSB are equal to '1'
 if (!(addr->addr[BD_ADDR_LEN - 1] & GAP_STATIC_ADDR))
 {
 // Generate static random address, 48-bits
 co_write32p(&addr->addr[0], co_rand_word());
 co_write16p(&addr->addr[4], co_rand_hword());

// The two MSB shall be equal to '1'
 addr->addr[BD_ADDR_LEN - 1] |= GAP_STATIC_ADDR;
 }
}

Dear TDC, Thank you for the reply. First Alternative: Use the default_app_generate_unique_static_random_addr callback function to generate the Unique BD Address, then store this BD Address on the SPI Flash. Via CLI you can read the specific address on SPI Flash to retrieve the BD Address and then burn it into the OTP. Second Alternative: Work with PLT , During Production, you can provide a csv file with all the BDA you want to be burned on the OTP header. Since you will provide the CSV you can guarantee that each device will have a unique BDA. Best Regards, OV_Renesas

Dear TDC, Thank you for the reply. You did not specify the offset and that is why it did not work on your side. For instance, try to use: SmartSnippetsToolbox.exe -type spi -chip DA14531 -jtag 480071106 -cmd read -offset 0x0f000 -file spi_out.txt It worked on my side: C:\Program Files\SmartSnippetsToolbox\SmartSnippetsToolbox5.0.24>SmartSnippetsToolbox.exe -type spi -chip DA14531 -jtag 480071106 -cmd read -offset 0x0f000 -file spi_out.txt
