no , I working with thé module GY-86 it have a three sensors , MS5611 HMC5883L MPU6050 , for the first sensor I used the library in sensor lib , and i modify the other library for the HMC5883L magnetometer , for work with the cdmc function , the problem was the mpu6050 need activated the i2c bypass for the communication ,i test only one sensor and this is the error . i need activated the mpu6050 before the HMC5883 .

Hello Andres

OK, so it was sequencing of the sensors that was the issue!

yes , with the GY-86 , is necessary first activate the opcion i2C Bypass in the MPU 6050 , for access the HMC5883 , thanks for all .
