I wonder if there are any major improvement in ESP32-S3 BLE power consumption ? I need to use the ESP BLE to wake up every few seconds to check if it is within the range of another BLE device (like the phone). For example, function esp_bt_controller_enable(ESP_BT_MODE_BLE) takes almost 600ms. Winner: ESP8266. Modem-sleep Model (mA) <25. ESP32-C3-WROOM-1 also supports a The ESP32 has Tensilica Xtensa LX6 32-bit Dual-Core processor operating at a frequency of 160/240Mhz whereas the ESP32-C3 Board has RISC-V 32-bit Single-Core processing running at a clock frequency of 160 MHz. How to Control a Servo with an ESP32 I am struggling with BLE in advertising mode. kengster. h) but would like to decrease the power consupmtion to something normal (not 110/130/160mA). Setting advertising interval to 1s reduces consumption further. Hi, In ESP32-C3 datasheet there is current consumption data (tables 15 and 16). The power consumption in the ESP32 devices given in the datasheet is up to 130 mA using "BT/BLE" which is just absurd. Refer to ESP32-C3 Wi-Fi Scan for a EspressifÕs ESP32-C3 Wi-Fi + BLE SoC HMAC Digital signature SPI I2S Temperature sensor LED PWM ADC TWAI Timers GPIO UART RMT GDMA BLE 5. As of now only BTDM (Dual Mode, both classic and BLE) is supported and my assumption is that it is because of the bluetooth classic that current ESP32 Power Consumption Tamed by Sleep Modes. For ESP32 the power is quite large and almost the same If you are using a dev kit board, choose one with a minimum of additional components that have a low consumption. kind regards Ian. According to the features used by an application, there are some sub sleep modes.
