cc2640 如何使用SNV纯30个字节的信息？

//NV_ID有一定范围

// Customer NV Items - Range 0x80 - 0x8F - This must match the number of Bonding entries
#define BLE_NVID_CUST_START 0x80 //!< Start of the Customer's NV IDs
#define BLE_NVID_CUST_END 0x8F //!< End of the Customer's NV IDs

0x80~0x8F都可以用（包含0x80、0x8F），每个ID号最多一次可写入252字节。实际可以写几个ID取决于所剩余SNV空间，并不是说可以把所有ID号都写满252字节。

您可以参考以下代码试试

#define BUF_LEN 1
#define SNV_ID_APP 0x80
uint8 buf[BUF_LEN] = {0,};
// Initialize application
simple_peripheral_init();
uint8 status = SUCCESS;
//Read from SNV flash
status = osal_snv_read(SNV_ID_APP, BUF_LEN, (uint8 *)buf);
if(status != SUCCESS)
{
DISPLAY_WRITE_STRING_VALUE("SNV READ FAIL: %d", status, LCD_PAGE5);
//Write first time to initialize SNV ID
osal_snv_write(SNV_ID_APP, BUF_LEN, (uint8 *)buf);
}
//Increment value and write to SNV flash
buf[0]++;
status = osal_snv_write(SNV_ID_APP, BUF_LEN, (uint8 *)buf);
