I am developing a code for implementing OTA over BLE. Since no BLE OTA available for ESP32 I am creating a custom mehtod. OTA works fine. But the time required is really high. In the process, I am only able to send 500 bytes per second via ESP_GATTS_EXEC_WRITE_EVT. and it almost takes 1 hour 5 minut...

Hi, I was trying to implement file uploading using the native method. I am able to upload the files without any problem but after the upload when I am trying to close the connection, it always returns FAIL. err = esp_http_client_close(client); if (err != ESP_OK) { ESP_LOGE(TAG, "Failed to close HTTP...

Can anybody please clarify

Hi, I am using 5 and 4 for UART num 1. uart_set_pin(UART_NUM, 5, 4, UART_PIN_NO_CHANGE, UART_PIN_NO_CHANGE); I would like to implement a light sleep-wake up from UART. But according to the Doc, I am seeing some confusing things in pins selections. Which is: "in ESP32, the wake-up signal can only be ...

Yes but in my case I don't have uart options provided in the PCB. trying via JTAG. Can anyone help??

Hi kubera, are you able to run esptool.py tool to read flash contents from the chip? It may help determine why programming over JTAG is failing. For instance, try reading back the flash contents, and compare it with the binary file. See if flash is not programmed at all, or there are only some prog...

Hi, I got a new esp32 chip, Trying to flash the code with JTAG options. The chip is fresh nothing is written into it. when I tried to upload the new partition.bin using the following command openocd -f board/esp32-wrover-kit-3.3v.cfg -c "program_esp filename.bin 0x10000 verify exit" programming was ...

Thanks for the reply, ESP_Sprite "abort() was called at PC 0x40082f56 on core 0 0x40082f56: lock_acquire generic at C:/Users/Desktop/esp-idf/components newlib/locks.c:143 " This is the error I am getting after the following flow. The program starts with wifi then shifts to BLE upon getting notificat...

Hi,
I have wifi and ble in separate tasks. implemented blufi along with it for provisioning.
while switching from one task to another I call vTaskDelete(handler). To delete that task. But unfortunately i doubut memory is not released by that call. How can we free the memory?
