Detecting the address of an external device using twi_scanner example program

[Vijayneerukanti]

I am using twi_scanner example program from nrf_sdk. when I run this program I could able to get the i2c address of some devices i.e., mpu6050 with address 0x68 and I am not able to get the address of the mpu9250. What could be the reason?

Is the device mpu9250 corrupted? 

Thanks

Hi Vijay

If it works for the mpu605, there is a high chance that the issue is not with the Nordic device or our software, but with either the hardware or the mpu9250.

I recommend that you double check you connections. Then you could try to look at the signals with an oscilloscope or logic analyzer to see if signals are sent to and from the mpu9250.
