Issues with changing MAC when batch flashing blueNRG-1 with BlueNRG-X Flasher Utility [Copy link]

 

 

MAC location: set to 0x10044BCC

******FLASH OPERATION******

Connected N.1 device by ST Link

17:57:53.953: Waiting device to flash -> Device connected
17:57:54.967: Device Identification -> BlueNRG-1
17:57:55.674: Mass Erase Operation -> SUCCESS
17:57:57.049: Device Flash Programming -> FAILED
17:58:00.917: Device Disconnection ->SUCCESS

17:58:02.009: Flash operation finished!

******END FLASH OPERATION******
I found that it cannot be written. I want to ask where the MAC address is written? Please help me.

#if SERVER
uint8_t role = GAP_PERIPHERAL_ROLE;
uint8_t bdaddr[] = {0xaa, 0x00, 0x00, 0xE1, 0x80, 0x01};

#else
uint8_t role = GAP_CENTRAL_ROLE;
uint8_t bdaddr[] = {0xbb, 0x00, 0x00, 0 xE1, 0x80, 0x02};
#endif

/* Configure Public address */
ret = aci_hal_write_config_data(CONFIG_DATA_PUBADDR_OFFSET, CONFIG_DATA_PUBADDR_LEN, bdaddr);
if(ret != BLE_STATUS_SUCCESS){
printf("Setting BD_ADDR failed: 0x%02x\r\n", ret);
return ret;
}

The flashing was successful, but the MAC address is still aa, 00, 00, E1, 80, 01. The code used is BLE_Examples\BLE_Chat

BlueNRG-X Flasher Utility writes the address you want to define to the specified location of FLASH

In your code, bdaddr uses the memory address defined, so the address written by BlueNRG-X Flasher Utility will not change your program.

If you want to use the BlueNRG-X Flasher Utility to program the address, you need to map the data corresponding to the FLASH address to bdaddr in your code.

For example, you can

Then use BlueNRG-X Flasher Utility to flash the firmware and the address will change.

OK, thank you.

Hello, I use BLUNRG-2, and I also need to batch program and use Utility to set the MAC address, but I can't set it successfully. Can you help me find out the reason? Thank you

Hello, I cannot modify the physical address successfully even if I directly modify it in the code without using the utility. What is the reason?

Did you use the official example or write your own code?

Thanks for the help, we modified it directly in the process, but we solved this problem in other ways, using broadcast data to distinguish different Bluetooth physical addresses.

Now there is another problem, that is, our sleep power consumption cannot be reduced, reaching 1mA

1. First, there is still broadcasting in sleep mode. We use aci_gap_set_non_discoverable() to turn off broadcasting, and then aci_gap_set_discoverable to turn on broadcasting, but we find that broadcasting cannot be turned on. After reading the documentation, we find that the device enters standby mode. Is it impossible to wake up through the set wake-up source? How should we turn off broadcasting?

2. Secondly, reduce power consumption by setting the gpio Mode

Have you read my reply in the private message? There is a link to the low power competition. There are many examples there. You can take a look.

Brother Xia, let me take a look.
