ESP32 2.4 GHz Dual Cores WLAN WiFi + Bluetooth 38 Pin MicrocontrollerESP32 Pin Description

ESP32 to 8266 Comparison:

  • ESP32 is a powerful device that runs through a 32-bit dual-core processor CPU with a clock speed of 160MHz to 240MHz while ESP8266 is a single-core CPU with a clock speed of around 80MHz. 
  • As we know the ESP32 has a higher speed compared to ESP8266 it consumes more power.
  • ESP8266 comes with 16 General Purpose Input Output (GPIO) Pins and other GPIO, UART, I2C, I2S and ADC Pins. ESP32 has more than 16 GPIO pins along with UART, I2C, I2S, ADC, DAC, and CAN Pins.
  • ESP32 comes with Bluetooth and WIFI together onboard whereas the ESP8266 comes with only WIFI.

1. Does NodeMCU ESP32 have Bluetooth?

  • The NodeMCU ESP-32S is an Expressif ESP32 based microcontroller and has Wifi, and dual mode Bluetooth, all in a single chip.

2. What is the difference between NodeMCU ESP8266 and NodeMCU ESP32?

  • ESP32 is the successor of ESP8266 and has extra features such as an extra CPU core, faster Wi-Fi and Bluetooth 4.0 (BLE) The ESP32 also has more GPIO pins as compared to the ESP8266.

3. On the ESP32, how do I enable Bluetooth?

  • To use Bluetooth on the ESP, a bluetooth sketch will need to be uploaded to the ESP via your PC

4. How many Bluetooth connections can the ESP32 support?

  • The ESP32 Bluetooth LE can connect to up to 9 client devices. But it is advised to keep this number under 3.

5. Can the ESP32 support both Wi-Fi and Bluetooth?

  • It is possible to simultaneously have both WiFi and Bluetooth connection enabled, but it is not recommended to do so as both the protocols use the same onboard antenna.
