Burning the hex to SPI FLASH,how to ensure that each MAC address is different?
Posted bywentong.lin0 points 1 replyHi Dialog,
I can load the hex to the SPI Flash successfully.
In the process of mass production, how to ensure that each MAC address is different?

Hi Wentong,
The MAC address, or actually the BD address could be written to a specific address in your SPI flash device. This has to be done for each device individually during production, (just like the parameters for the XTAL calibration). Your code has to take care for copying the data form the flash location to the right registers (BLE_BDADDRL_REG, BLE_BDADDRU_REG) of the DA14580.
