Use debugging tools provided by the ESP32-C3 development environment to inspect the BLE advertisement packet contents. This can help identify any discrepancies or issues with the packet format. Also, make sure that you are using the latest firmware for the ESP32-C3. Sometimes, firmware updates can r...

Make sure that the ESP32-C3 is configured correctly to include both Service Data and Manufacturer Data in its BLE advertisement packets. You can make an ESP32-C3 DevBoard. It's a basic ESP32-C3 DevBoard with CH340C USB to serial chip: https://www.pcbway.com/project/shareproject/ESP32_C3_DevBoard_208...

The ESP32 is a popular choice for IoT projects, offering dual-core processing, Bluetooth (including BLE), Wi-Fi connectivity, and GPIO pins. There are some alternatives too. The Raspberry Pi is a versatile and widely supported development board that offers dual-core processing, Bluetooth and BLE (5....

You can modify your code like this: #include <esp_sleep.h> #include <driver/gpio.h> bool isFirstBoot = true; void IRAM_ATTR handleInterrupt(void* arg) { // Handle interrupt event here } void setup() { Serial.begin(115200); if (isFirstBoot) { Serial.println("\nBoot"); // Initialize GPIO pins gpio_con...

You can consider JSON streaming.

You can modify your code to manually set the speed to 10Mbps: esp_eth_autoneg_t auto_nego_en = 0; // Disable auto-negotiation esp_eth_speed_t eth_speed = ETH_SPEED_10M; // Set speed to 10Mbps // Set auto-negotiation status ESP_ERROR_CHECK(esp_eth_ioctl(eth_handle, ETH_CMD_S_AUTONEGO, &auto_nego_en))...

You can use the I2C bus in a multi-master configuration, where both the ES8388 driver and your code can share access to the bus.

Here is a thread on compilation error in ESP32-S3. You can check if it helps:https://forum.arduino.cc/t/esp32-s3-sud ... or/1177237

you can buffer incoming data in RAM before entering sleep mode and then process it after waking up.
