+# OSC MESSAGES
+
+ESP-IMU receives messages on UDP **input port** (default 9000)  
+The last IP that sent a message will receive all messages from ESP-IMU on **target port**  
+Default **target IP** can be changed through webserver
+**input port** and **target port** can be changed through webserver
+
+## to ESP-IMU
+- **/calibration** :  
+triggers a gyro calibration process, useful if the sensor drifts. Turn the sensor all the way around during 15 seconds
+
+## from ESP-IMU
+
+- **/button/[A, B, C]** :  
+message is sent on A/B/C button state change  
+1 when pressed, 0 when released
