hello everyone,
in my project i need to advertise the sensor data as well as connecting the BLE TAG . in detail i am using nrf52810 with mpu6050 and i want read the accelerometer and Gyro-meter , battery data which i need to advertise in the nrf connect mobile application and also whenever necessary i want to connect BLE and change the angle of Gyro-meter since i am using ble_app_template example source code and i could not advertise the data please help me to resolve this problem . for more information please find the below attachment of my code .
thank you.
