10.6 NVRAM Programming Example

The following code sample provides an example of writing a Bluetooth device address to NVRAM and reading it back.

#define APP_VS_ID

BD_ADDR bd_addr_write = { 0x01, 0x02, 0x03, 0x04, 0x05, 0x06};

BD_ADDR bd_addr_read;

void test_nvram_read_write_app( )

{

uint8_t written_bytes, read_bytes;

wiced_result_t status;

/* Write BD ADDR to NVRAM */

written_bytes = wiced_hal_write_nvram( APP_VS_ID, BD_ADDR_LEN, bd_addr_write,

&status );

WICED_BT_TRACE("status of nvram write %d, number of bytes written %d\n", status,

written_bytes);

/* Read BD ADDR from NVRAM */

read_bytes = wiced_hal_read_nvram( APP_VS_ID, BD_ADDR_LEN, bd_addr_read,

&status );

WICED_BT_TRACE( "status of nvram read %d, number of bytes read %d\n", status,

read_bytes);

wiced_bt_trace_array( "BD_ADDR read back : \n", bd_addr_read, BD_ADDR_LEN);

}
