Protect BT Address in NVRAM

[aglier]

Hi,

we want to protect our Bluetooth address from beeing deleted when the firmware is updated.

We use "wiced_hal_write_nvram" to store the Bluetooth address in NVRAM.

Is there a way to protect it from beeing overwritten or is there another way to store data in non volatile memory

for this purpose?

Used hardware. CYBT-343026

Thanks in advance

Best regards

Alex

And  if you have MCU to control  CYBT-343026,  generally, you can save BT address in the MCU flash, after update BT firmware,  you can rewrite address by the wiced_hal_write_nvram. Or you can change address derictly in firmware* .hex file when you download firmware.
