There are a few potential advantages of using bluetooth to connect to and control an embedded device. I have previously paired the ESP successfully to the phone, using an Arduino code example and a bluetooth terminal so the hardware is confirmed to be working. I have to upload the same code again to make it run. Thus using the Arduino SPI API, it should work, like all other devices (the ESP32 Arduino Core implementation conforms to the API defined by Arduino, of course I would check if your board's pinout corresponds to the Espressif defined ESP32 After the big success of the ESP8266, the ESP32 is a new chip from Espressif that combines WiFi and Bluetooth wireless capabilities with two CPU cores and a decent hardware peripheral set. The ESP32 should appear as a Bluetooth device named "ESP32 once I reset the esp32, it starts working again with the same problem. Instead, it takes care of storing the MAC with ESP32 and ESP8266, it's quite more easier to add some kind of a p2p integration with a computer, since the firmware is already available in open source state and can be modified to Check your device manager for an unknown device when you plug it in and search for the driver. Copy ESP32 #1 code, paste to Arduino IDE #1 and save it use our content on any other websites. Serial port names start with COM in Windows. The functionality I'm looking for is to be able to connect any PC to the ESP device as an "Outgoing" COM port and be able to send and receive data just like uart_read_bytes and uart_send_bytes works. The experiment on ordinary bluetooth is done by transferring data from phone to ESP32 and vice versa, and the experiment on low-energy bluetooth is done by setting two ESP32 as server and scanner So I'm trying to replace the IP Address of an ESP32 with a name, using the WiFi.
