I am facing an issue connecting the STM32F4 NUCLEO-F429ZI board to an HMI screen that uses RS232 and RS485 communication standards. The HMI can communicate successfully with my computer, but the STM32 board cannot communicate with the computer exce...
"I'm working with STM32 NUCLEOF429ZI but I encountered this error. Right after I plugged in the cable to upload the program, the txt file showed this error. Please help me identify the cause and how to fix it.""The interface firmware FAILED to reset/...
I’ve successfully implemented data transmission between my STM32 NUCLEO F429ZI and an MQTT broker. Now, I want to enhance the security of this communication by configuring TLS. Initially, I would like to set up TLS without requiring CA certificates f...
I am running an STM32 NUCLEO F429ZI project connected to HiveMQ, with the following details in the mqtt_app.c file using LWIP and MBEDTLS:
char* strUrlDefault = "mqtt://broker-dev.vconnex.vn:888";
char* strUsernameDefault = "SmartHome";
char* strP...
i transmitted/received data from stm32 to my computer however, i transmitted "123" but stm32 received "67 B3 06". I used uart 2(PD5 Tx, PA3 Rx)ReceiveTransmit /* USER CODE BEGIN Header */

I'm using USART 3 with my computer via STLINK and communication is normal, but if I switch to using USART2 (PD5 is TX and PD6 is RX) and of course the code will also change from uart3 to uart2 but it won't transmit. receive. During that process, I st...
So, again I have tested the STM32 separately with the computer, but the STM32 does not receive the messages sent from the computer.I have tried debugging both the hardware and software.I'm using DMG80480C070_15WTR displayDisplay SpecificationsResolu...
