Thanks a lot @WiFive.. it works now

Ok so I partially fixed the issue and now I can read the letter "p" that is being transmitting from a pic microcontroller. but I'm having this Guru meditation error after the buffer get full. I tried to flush after the loop but it didn't help. The code is below : #include "freertos/FreeRTOS.h" #incl...

At the beginning, I was using only the second one (the one terminated with 0) but then I added the first one (before the while loop) just to compare.

I have already specified them earlier but then I changed them into default hoping it could help!

Hello Guys, I'm trying to use ESP32 to publish topics within Mosquitto via CLion IDE (Windows 10), I'm trying to link the library (Mosquitto.lib) with ESP-IDF tools so that it helps the compiler to read it. To do that, I added this path to environment variables : C:\Program Files\mosquitto\devel The...

#include <stdio.h> #include <esp_vfs_fat.h> #include <esp_modbus_slave.h> #include <esp_err.h> #include "UART.h" void app_main() { int uart_buffer_size = (1024*2); const int uart_num = UART_NUM_2; uart_config_t uart_config = { .baud_rate = 115200, .data_bits = UART_DATA_8_BITS, .parity = UART_PARIT...

@ESP_Sprite.. So i did add '\0' at the end of the string but nothing changed, the serial monitor is always rubbish. what's weird to me is that i can see a response on the oscilloscope when i do an echo, so that means my esp32 is receiving correctly via rx buffer and write the data back via tx buffer.

@ESP_Sprite.. So, i let the pic transmits a letter (uint8_t) instead of an integer and the final code is as below: void app_main() { int len; int uart_buffer_size = (1024*2); const int uart_num = UART_NUM_2; uint8_t data[128]; uart_config_t uart_config = { .baud_rate = 9600, .data_bits = UART_DATA_8...

Hi @ESP_Sprite,

It's the same code, i just replaced : (Int data = 0) By (int *data = (int *) malloc(uart_buffer_size);)
