I successfully compiled and uploaded the code to an Arduino Nano; however,, I am struggling to compile the code to ESP32. I have included all the necessary libraries for ESP32 and BLE. I will be using an L298n an Android phone and a ESP32. Perhaps I missed something. My config for ESP32 in Arduino IDE: //MCUs

define NANO 328 //Atmega328p

define ESP32 32 //ESP32

//Robot bodies with Atmega328p as MCU --> Select Arduino Nano as board

define DIY 0 // DIY without PCB

define PCB_V1 1 // DIY with PCB V1

define PCB_V2 2 // DIY with PCB V2

define RTR_TT 3 // Ready-to-Run with TT-motors

define RC_CAR 4 // RC truck prototypes

define LITE 5 // Smaller DIY version for education

//Robot bodies with ESP32 as MCU --> Select ESP32 Dev Module as board

define RTR_TT2 6 // Ready-to-Run with TT-motors

define RTR_520 7 // Ready-to-Run with 520-motors

define MTV 8 // Multi Terrain Vehicle

define DIY_ESP32 9 // DIY without PCB

//------------------------------------------------------// // SETUP - Choose your body //------------------------------------------------------//

// Setup the OpenBot version (DIY, PCB_V1, PCB_V2, RTR_TT, RC_CAR, LITE, RTR_TT2, RTR_520, DIY_ESP32,OPENBOT DIY)

define OPENBOT DIY_ESP32

SETTINGS - Global settings //------------------------------------------------------//

// Enable/Disable no phone mode (1,0) // In no phone mode: // - the motors will turn at 75% speed // - the speed will be reduced if an obstacle is detected by the sonar sensor // - the car will turn, if an obstacle is detected within TURN_DISTANCE // WARNING: If the sonar sensor is not setup, the car will go full speed forward!

define NO_PHONE_MODE 1

// Enable/Disable debug print (1,0)

define DEBUG 1

// Enable/Disable coast mode (1,0) // When no control is applied, the robot will either coast (1) or actively stop (0) boolean coast_mode = 0;

My snippet for DIY ESP32 //-------------------------DIY_ESP32----------------------//

elif (OPENBOT == DIY_ESP32)

const String robot_type = "DIY_ESP32";
