STM32f1xx UART slow and when I added another logic it just didn't works I made a simple program on an ESP32 to send dummy data with something like this $DUMMYDATA,0,1I've tried using another ESP32 as a receiver and it works perfectly. My goals is implement the same thing to my STM32F103C8T6. Here's my code for the first attempt.while (1)
{
HAL_UART_Receive(&huart2, receivedData, sizeof(receivedData), 100);
CDC_Transmit_FS((uint8_t *)receivedData, strlen(receivedData));
}It works but the data is corrupted⸮0kTԽ⸮5⸮⸮c 8 ⸮⸮ d⸮֩⸮&⸮⸮.⸮Z⸮�?|!Qi;⸮1⸮⸮z\⸮9⸮$DUMMYDATA,1,0Then I changed the third line to something like thisHAL_UART_Receive(&huart2, receivedData, sizeof(receivedData), HAL_MAX_DELAY);Now it works perfectly but with downside it just became really slow. Then I tried to add a simple logic to parse the data while (1)
{
HAL_UART_Receive(&huart2, receivedData, sizeof(receivedData), HAL_MAX_DELAY);
strcpy(dataMode, strtok(receivedData, ','));
strcpy(latitude, strtok(NULL, ','));
strcpy(longitude, strtok(NULL, ','));
