esp_bufi_send_custom_data() function not free the memory used

Hello I use the blufi library to configure Wifi on ESP32 and send a 1Mb file to ESP32. For this, the file is sent in blocks of 255 bytes The ESP32 responds for each received block with, esp_bufi_send_custom_data, and the heap decreases. I can't receive the full file because at 91%, the heap memory i...

Re: Bluetooth discover

Hello:

Thanks, but I use the ESP_IDF framework with Vicual Code Studio and Platformio without arduino.

Also I think that is a different question, I think taht me problem is Windows and not the ESP32 framework

Thanks

UART0 for RS485 Hall Duplex, RTS pin not works

Hello: I have write a task for working with a RS485 transceiver with a RTS pin for flow control. I test my task over uart1, and works fine (I have a RS485 transceiver at uart1 and other over uart0) I have disabled all log at uart0 and change form uart1 to uart0 (also change the pin out) but over uar...

Re: How UART working?

Then this means that the Uart working mode is 1 Data input in to the FIFO buffer 2.Data go from FIFO to Uart buffer when a: the FIFO is full (120 bytes) b: there is not more data after timeout* * this timeout is not the timeout from uart_read_bytes, this is the timeout of one character, for example ...

Re: How UART working?

120 bytes seems a hardware limit. is it? well first conts int rxBytes = uart_read_bytes(UART_NUM_1, data, RX_BUF_SIZE,40/portTICK_RATE_MS); I read 120 bytes wait 30 ms vTaskDelay(30/portTICK_RATE_MS); in this moment I expect there are 30 new bytes in the FIFO then I do conts int rxBytes = uart_read_...
