supported to begin with (you would have to cobble something together from the ESP-IDF startup code and the LL driver layers) and impossible if you want to use WiFi: although you could potentially modify it for another RTOS, the WiFi drivers expect some kind of RTOS as the underlying ...
My product using ESP32 couldn't pass the Carrier Sense test in the WiFi test in Japan. I saw a new API esp_wifi_set_dynamic_cs() is added in v5.2.2. So I upgraded the SDK version and add this API in my WiFi init code: ESP_ERROR_CHECK(esp_netif_init()); ESP_ERROR_CHECK(...
To connect to it I use (from a browser) http://192.168.4.1 It is possible to use some technique to be able to browse to it by name instead of its IP address? Eg. http://MyESP32 (I have used NetBios to do something similar in the past on Ethernet) ...
My question is that to reach this goal which one of the available examles in esp_idf is more suitable to use? Since I see both examples named "ble_spp_server" and "gatt_server", and I don't undrestand which one should I use for this purpose?
Connect the ESP32 CYD to the computer; Click on "Tools" menu -> "ESP32 Sketch Data Upload" line; ClickYesin the pop-up window. The program is going to format the built-in flash memory. Step 7: Clear EEPROM To use Midbar, you first need to clear EEPROM. ...
The ESP8266 has by far not enough RAM to hold this amount of information in the RAM. That’s why we used an old trick known from the first home computers to reduce the color information per pixel. Instead of 16bit “True Color” we use a palette of defined colors. Before the library...
I have tried in ESP AP mode and with esp_wifi_internal_reg_rxcb I can receive ARP and other packets but in STA mode I can't. I have been digging in the lwip source code and esp-idf framework source code but it is too complex for me. I understand the posible s...
OTA: https://github.com/espressif/esp-idf/tr ... system/ota But this project seems to use the ESP32 as an HTTP client, connecting to a server running on a computer, and both the ESP32 and the computer being connected to the same local network created by a r...
You may want to use LNA with a voltage source other that a thermocuple. To do so, first characterize the LNA with this particular voltage source. There are two examples provided specifically for this purpose, one for Arduino and one for ESP-IDF. They provide identical functionality showing LN...
How to Use a Debugger on an ESP32: Have you ever wanted to take a peek inside your code to see why it's behaving the way it is? Traditionally in ESP32 projects, you would have had to add endless print statement to try figure out what was going on, but th
