read gyro value when max30102 sensor is also connected #75

I think this is a bug , when i have both sensor connected either in the same i2c port or different i2c on the same mcu, the gyro does not return any value, it only display 0 for all 3 value which in my case i use yaw, roll, pitch. I already try for euler value, also the same.

so in void loop, i usually collecting a few data for the max30102 then i read the data from mpu9250. what i do to avoid return 0 value. i make sure in void loop the first thing i do is to read mpu9250 a few times consecutively , then i proceed with the usual flow that i have. and it fix the problems.

however , the value from the mpu9250 fluctuate a little bit which not happening when only mpu9250 is connected. i not yet play around with the mpu9250 setting. just want to let you know, i think it is a bug but im not sure.

im using: esp32 dev board - wrover e platform io v2.4.0 arduino framework mpu9250 library v 0.4.8 sparkfun mpu9250 - v1.1.1

I think it's not a library bug if it works without any other libraries. Could you try to analyze your circuit and let me know about the detail if you still have the problem?

Sure i will have a look again, i not yet analyse it with logic analyser, but what i can say using mpu9250 with mlx90614 based on adafruit library ,does not produce this kind of problems.
