TRNG DA14531

我总是得到相同的输出，如果我重新加载和启动固件。我不应该这么认为。

代码:

Void user_app_init(Void) {arch_printf("\r\n\r\nuser_app_init\r\n");//初始化随机数生成器种子使用随机比特从TRNG init_rand_seed_from_trng();//初始化标准c rand()函数与trng随机数srand(trng_state_val);//测试:循环通过随机数生成器来测试随机数生成器…(uint8_t我= 0;我< 10;i++){//为AES-128密钥获取16字节的随机数(uint8_t i=0;我< ENC_DATA_LEN;i++){generated_challenge[i] = rand()%0xFF;} user_app_format_data("CHALLENGE"， generated_challenge, 16); } app_param_update_request_timer_used = EASY_TIMER_INVALID_TIMER; // Initialize Manufacturer Specific Data mnf_data_init(); // Initialize Advertising and Scan Response Data memcpy(stored_adv_data, USER_ADVERTISE_DATA, USER_ADVERTISE_DATA_LEN); stored_adv_data_len = USER_ADVERTISE_DATA_LEN; memcpy(stored_scan_rsp_data, USER_ADVERTISE_SCAN_RESPONSE_DATA, USER_ADVERTISE_SCAN_RESPONSE_DATA_LEN); stored_scan_rsp_data_len = USER_ADVERTISE_SCAN_RESPONSE_DATA_LEN; default_app_on_init(); }

控制台输出：
