CC3220SF Wi-Fi direct,利用network terminal例程,无法修改Device Name

开发板型号:C3220SF

利用例程Network Terminal,其它地方没有进行修改,只改动了mainthread如下:

void * mainThread(void *arg)
{int32_tRetVal ;pthread_attr_tpAttrs_spawn;struct sched_param  priParam;struct timespects = {0};/* Initializes the SPI interface to the NetworkProcessor and peripheral SPI (if defined in the board file) */SPI_init();GPIO_init();/* Init Application variables */RetVal = initAppVariables();/* Init Terminal UART */InitTerm();/* initialize the realtime clock */clock_settime(CLOCK_REALTIME, &ts);/* Switch off all LEDs on boards */GPIO_write(CONFIG_GPIO_LED_0, CONFIG_GPIO_LED_OFF);GPIO_write(CONFIG_GPIO_LED_1, CONFIG_GPIO_LED_OFF);GPIO_write(CONFIG_GPIO_LED_2, CONFIG_GPIO_LED_OFF);/* Create the sl_Task internal spawn thread */pthread_attr_init(&pAttrs_spawn);priParam.sched_priority = SPAWN_TASK_PRIORITY;RetVal = pthread_attr_setschedparam(&pAttrs_spawn, &priParam);RetVal |= pthread_attr_setstacksize(&pAttrs_spawn, TASK_STACK_SIZE);/* The SimpleLink host driver architecture mandate spawnthread to be created prior to calling Sl_start (turning the NWP on). *//* The purpose of this thread is to handleasynchronous events sent from the NWP.* Every event is classified and later handledby the Host driver event handlers. */RetVal = pthread_create(&gSpawn_thread, &pAttrs_spawn, sl_Task, NULL);if(RetVal != 0){/* Handle Error */UART_PRINT("Network Terminal - Unable to create spawn thread \n");return(NULL);}/* Before turning on the NWP on,reset any previously configured parameters *//*IMPORTANT NOTE - This is an example reset function,user must update this function to match the application settings.*/RetVal = sl_WifiConfig();if(RetVal < 0){Handle ErrorUART_PRINT("Network Terminal - Couldn't configure Network Processor - %d\n",RetVal);return(NULL);}/* Turn NWP on */RetVal = sl_Start(NULL, NULL, NULL);if(RetVal < 0){/* Handle Error */UART_PRINT("sl_start failed - %d\n",RetVal);return(NULL);}/*Set Mode*/_i16 Role;_i16 Status;Status = sl_WlanSetMode(ROLE_P2P);if(Status){UART_PRINT("sl_WlanSetMode failed\n");return(NULL);}Status = sl_Stop(0);Role = sl_Start(NULL, NULL, NULL);if(ROLE_P2P != Role){UART_PRINT("ROLE_P2P != Role\n");return(NULL);}/*Set Network Configuration*/SlNetCfgIpV4Args_t ipV4;ipV4.Ip= (_u32)SL_IPV4_VAL(192, 168, 0, 108);ipV4.IpMask= (_u32)SL_IPV4_VAL(255, 255, 255, 0);ipV4.IpGateway= (_u32)SL_IPV4_VAL(192, 168, 0, 1);ipV4.IpDnsServer = (_u32)SL_IPV4_VAL(192, 168, 0, 1);Status = sl_NetCfgSet(SL_NETCFG_IPV4_STA_ADDR_MODE,SL_NETCFG_ADDR_STATIC, sizeof(SlNetCfgIpV4Args_t), (_u8*)&ipV4);if(Status){UART_PRINT("sl_NetCfgSet failed\n");return(NULL);}/*Set Device Name*/_u8 device_name[] = "Simple_WiFi_Direct";Status = sl_NetAppSet(SL_NETAPP_DEVICE_ID, SL_NETAPP_DEVICE_URN, strlen(device_name), (_u8*)device_name);if(Status){UART_PRINT("sl_NetAppSet failed\n");return(NULL);}UART_PRINT("Success!");return(0);
}

但是最后串口那里输出 sl_NetAppSet failed。即没有成功修改device name。

这是怎么回事。

Viki Shi:

请参考以下文档的3.9节,进行device name的修改:
