Re: Ethernet example for W5500 does not compile OK

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 apparently...

Ethernet example for W5500 does not compile OK

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 CONFIG_...

Strange behaviour on init of BLE/nimBLE

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 c...

Unable to flash firmware

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 -...

Re: Ways to make binary smaller?

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 info...

Re: Ways to make binary smaller?

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 in...

Re: Communicationg TWO ESP32 Boards

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 I ...
