It was developed for the lack of security, which was in ESP8266. Pros: ESP32 offers you dual-core 160MHZ to 240MHZ; You can control and monitor your device with the help of Wi-fi or Bluetooth at a very low price. ESP32 offers you more GPIOs; ESP32 gives you a high speed of 150Mbps. Cons:
Oct 05, 2019 · I have the esp32 with the ble firmware version 0.93. My access point is a Ubiquiti long range and behind it is an Asus router. I have given a static ip to the esp32 in my router software., but still it will disconnect sometimes. Then the esp32 is making a ap itself and if I login to this, the config is empty.
In this case, you can increase the range of your WiFi network with a repeater. The WiFi will also be ideal for making objects to interact with an online service (publish values hopefully reach 1100m in open field at very low speed (check under real conditions).
