autoPlane PID system made for providing flight stabilization and automatic flight capabilities to an RC plane, these capabilities allow the plane to maintain a stable flight path and follow a specified course angle set by the user. This system can be calibrated and configured through Bluetooth communication and sends telemetry data to a ground station using a LoRa module.
- ESP32
- LoRa SX1278
- MPU9250
- BMP180
- 2 Servos (pitch and roll)

- RC plane used a V-tail configuration, therefore there's not direct yaw control nor servos used for this movement.
- Bluetooth communication can be used for magnetometer calibration, data logging or arming/disarming servos.
- This code has capabilities to add a buzzer and voltage and current sensors.
- Constant variables are stored in a struct data type to differentiate between various uses of constants.
When using Bluetooth communication some functions can be executed with the following input values:
- 10: Magnetometer and IMU calibration.
- 20: Disarms servos.
- 21: Arms servos.
