WIZ550io 모듈에서 MQTT 사용 가능할까요?

Question

안녕하세요. WIZ550io 모듈을 이용해서 Socket 통신은 잘 사용하고 있습니다. MCU는 STM32F407 입니다. 고객 요청으로 MQTT 프로토콜를 구현하려고 하는데 지원이 가능 한가요? ioLibrary에 있는 MQTT Source 를 이용해서 시도 중인데 접속이 안되어 문의 합니다. 초기화는 mqtt_interface.h 를 참고해서 아래와 같이 했습니다. 관련소스만 붙혀넣었습니다. wiz_NetInfo gWIZNETINFO = { .mac = {0x00, 0x08, 0xdc, 0x76, 0xed, 0x03}, .ip = {192, 168, 0, 200}, .sn = {255, 255, 255, 0}, .gw = {192, 168, 0, 1}, .dns = {8, 8, 8, 8}, .dhcp = NETINFO_STATIC }; unsigned char targetIP[4] = {192, 168, 0, 26}; // mqtt server IP unsigned int targetPort = 1883; // mqtt server port uint8_t mac_address[6] = {}; unsigned char tempBuffer[BUFFER_SIZE] = {}; struct opts_struct { char* clientid; int nodelimiter; char* delimiter; enum QoS qos; char* username; char* password; char* host; int port; int showtopics; } opts ={ (char*)“stdout-subscriber”, 0, (char*)“
”, QOS0, NULL, NULL, (char*)targetIP, 1883, 0 }; // @brief messageArrived callback function void messageArrived(MessageData* md) { unsigned char testbuffer[100]; MQTTMessage* message = md->message; if (opts.showtopics) { memcpy(testbuffer,(char*)message->payload,(int)message->payloadlen); *(testbuffer + (int)message->payloadlen + 1) = "
"; printf("%s
",testbuffer); } if (opts.nodelimiter) printf("%.*s", (int)message->payloadlen, (char*)message->payload); else printf("%.*s%s", (int)message->payloadlen, (char*)message->payload, opts.delimiter); } int main(void) { /* USER CODE BEGIN 1 */ /* USER CODE END 1 */ /* MCU Configuration--------------------------------------------------------*/ /* Reset of all peripherals, Initializes the Flash interface and the Systick. */ HAL_Init(); /* USER CODE BEGIN Init */ /* USER CODE END Init */ /* Configure the system clock */ SystemClock_Config(); /* USER CODE BEGIN SysInit */ /* USER CODE END SysInit */ /* Initialize all configured peripherals / MX_GPIO_Init(); MX_DMA_Init(); MX_ADC1_Init(); MX_RTC_Init(); MX_SPI2_Init(); MX_TIM6_Init(); MX_TIM7_Init(); MX_USART1_UART_Init(); MX_USART2_UART_Init(); MX_USART3_UART_Init(); MX_I2C1_Init(); / USER CODE BEGIN 2 */ HAL_TIM_Base_Start_IT(&htim6); // Timer6 Start HAL_TIM_Base_Start_IT(&htim7); // Timer7 Start HAL_UART_Receive_IT(&huart1, &bytRx1_Data, 1); // PC Interface HAL_UART_Receive_IT(&huart2, &bytRx2_Data, 1); // LCD Module HAL_UART_Receive_IT(&huart3, &bytRx3_Data, 1); // SD Module HAL_ADC_Start_DMA(&hadc1, (uint32_t *)nlAdcValue, 4); // Start the ADC in DMA mode Initialize_Variable(); reg_wizchip_cs_cbfunc(csEnable,csDisable);// CS function register #ifdef USE_DMA reg_wizchip_spi_cbfunc(spiDmaReadByte, spiDmaWriteByte);// SPI method callback registration reg_wizchip_spiburst_cbfunc(spiReadBurst, spiWriteBurst);// use DMA #else reg_wizchip_spi_cbfunc(spiReadByte, spiWriteByte);// SPI method callback registration #endif wizchip_initialize(); if (gWIZNETINFO.dhcp == NETINFO_DHCP) // DHCP { wizchip_dhcp_init(); while (DHCP_run() != DHCP_IP_LEASED) // wiz_delay_ms(1000); HAL_Delay(1000); } else // static { ctlnetwork(CN_SET_NETINFO, &gWIZNETINFO)…

안녕 하십니까, STM32용 예제 코드 없지만 다음 github repo에 참조하시면 될 것 같습니다 github.com Wiznet/RP2040-HAT-C/blob/main/examples/mqtt/publish_subscribe/w5x00_mqtt_publish_subscribe.c /** * Copyright (c) 2021 WIZnet Co.,Ltd * * SPDX-License-Identifier: BSD-3-Clause */ /** * ---------------------------------------------------------------------------------------------------- * Includes * ---------------------------------------------------------------------------------------------------- */ #include #include #include "port_common.h" #include "wizchip_conf.h" #include "w5x00_spi.h" #include "mqtt_interface.h" This file has been truncated. show original 또는, MQTT broker conf에서 authentication 세팅이 되있는지 확인하시면 좋을 것 같습니다. 감사합니다.
