Hello:

I have found the problem. I have been using the https://github.com/wolfeidau/esp32-blufi explample.
And I have found a error at blufi_event_callback(), this function define a nvs_handler, open it, but not close it.

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 ...

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

Hello:

I don´t know if this is the apropiate forum for this question.

I'm try to discover ESP32 bluetooth from PC with WIndows 10. I use BLUFI library and I can see the ESP32 BLUFI_DEVICE at Windows bluetooth add device configuration page, but I can´t found any function to make it with a Windows ...

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 ...

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 ...

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 ...

Can I change the 120 bytes of FIFO to 250 for example? how?

Hello:

I'm trying to read 189 bytes from UART, but some times I doesnt work well.

void init_uart() {
const uart_config_t uart_config = {
.baud_rate = 9600,
.data_bits = UART_DATA_8_BITS,
.parity = UART_PARITY_DISABLE,
.stop_bits = UART_STOP_BITS_1,
.flow_ctrl = UART_HW_FLOWCTRL_DISABLE ...

Hi:

I'm working with Visual Code Studio and Platformio.
