static assertion failed with "please enable bluetooth in menuconfig to use bt.h". I get this error when I try to build bluetooth spp server demo. my sdkconfig.defaults is as follows; # Override some defaults so BT stack is enabled # in this example # # BT config # CONFIG_BT_ENABLED=...
I am using Bluedroid BLE stack in order to do BLE with an Esp32S3 chip and everything is ok. The stack runs normally, I have no problems with it. Now, I would like to enable Wifi in SoftAP mode when the chip starts in order to have the possibility to upgrade the firmware via OTA...
Once this server is started, you can access it even in your mobile phone using nRF Connect in just two steps as below: Step 1: Open the scanner and connect to your Bluetooth device Step 2: After connecting to your ESP32, you can check the characteristic, and it will be displaying your...
Make sure that Bluetooth on your phone is on and click ‘Start Scanning’, as long as the esp is in range and powered on you should be receiving some temperature value. Possible errors: -1000 :: This means that your device couldn't find the ESP. make sure that Bluetooth is on and tr...

In this manner, we can connect up to 8 LCDs to the same line. There is one more thing, the ESP32 takes 7 bit address for the I2C device. All the functions, which are included in the library of ESP32 will shift this address to the left by 1 bit, 0x27<<1, and the LSB here...
I purchased the ESP-WROVER-KIT v4.1 from Digikey and can not get the external 32.768 crystal to be accepted when I enable it with menuconfig. The output is always W (321) clk: 32 kHz XTAL not found, switching to internal 150 kHz oscillator I've tried deep sleep examples which ...
In esp32c3 technical reference 26.4.2, there is: UARTn can access FIFO via register UART_FIFO_REG. You can put data into TX FIFO by writing UART_RXFIFO_RD_BYTE, and get data in RX FIFO by reading UART_RXFIFO_RD_BYTE. If I get it right, it means that reading the lower 8 bits ...
If you want to get overall free memory available, use the function esp_get_free_heap_size(). An example usage (in ESP-IDF) is: static const char *TAG = "Main File"; ESP_LOGI(TAG, "[APP] Free memory: %d bytes", esp_get_free_heap_size()); ...
package in Arduino IDE, it’s crucial to ensure that you have the latest version of Arduino IDE. ESP32 has been known to have compatibility issues with previous versions of Arduino IDE. Therefore, we recommend deleting any old versions and installing the latest ones to avoid any potential ...
