Anyone listening here? I have the same problem. ESP-IDF 4.4.1 file_serving example, SD card enabled via menuconfig. Files doe not seem to be saved to SD.

Hi Ondrej, thanks for your response !

The last output from the original code that I get in the monitor is:

I (348) cpu_start: Starting scheduler on PRO CPU.
I (0) cpu_start: Starting scheduler on APP CPU.

I placed a number of logs inside the conditional code blocks. They do not appear, so ...

Hi,

I recently updated from ESP-IDF 4.2 to 4.4

Now I want to compile the Ethernet basic example, but I have no succes. The code compiles without errors but at run-time it does not show the expected output.

The example contains a number of conditional compilation statements, such as e.g.: #if ...

I have a problem with initializing a BLE/nimBLE controller. I use an ESP32 (Heltec LORA32 V2) and ESP-IDF 4.2 in the command line.

When I try to initialize a nimBLE controller with esp_bt_controller_init(&bt_cfg)) I see the following messages in my monitor screen:

I (1631) BTDM_INIT: BT controller ...

Hi, I want to use a component, but have some problems configuring it. I use ESP-IDF 4.2

I placed the files and subfolders into my project/components folder. The componenets header files are in project/components/include and the source files (.cpp) in project/components/src

I have a CMakeLists.txt ...

Hi I have a Heltec Lora32 board that worked fine until now. When I now want to flash firmware with idf.py -p COM3 flash I get a "A fatal error occurred: Timed out waiting for packet content". I read somewhere that more info about the root cause can possibly be obtained via the command "espefuse.py ...

My app uses esp_wifi and mqtt_client for connection with the outside world. The total app is too large. I already implemented options described here: https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/performance/size.html.

1) this is not enough
2) I need access to debugging ...

Hi @kolban,

I find your proposed method very attractive! I am relatively new so I want to understand this a bit more before I try this.

1)
The most important, in the end you say: "The obvious downside of this is that (absent an ability to refresh the ESP-IDF) you are stuck with a constant ESP-IDF ...

Thanks @chegewara.

Does anyone know about existence of a well-written lib for communication via I2C / UART between peers?

Hi, I need a communication means that has low memory usage.

I want to free up memory by removing WIFI and MQTT code to have more space for the core of the project. I could add a second board that has a wired connection with the first board and does the wireless communication with the network.

Can ...
