Hi Ramu,

Could you help explain the issue. Is Bqstudios not recognizing the gauge whenever you start the app?

Thanks,

Adam

I’m not using Bqstudios .

im attempting to communicate with a BQ27750 battery fuel gauge via the I²C1 bus on a Linux-based embedded platform (likely Qualcomm MDM9607). However, the device is not detected using i2cdetect, and no response is received at the expected I²C address 0x55

Hi Ramu,

We do not support Linux or Linux-based platforms. This is the reason you are not getting any communication.

Thanks,

Adam

Okay. Can you check the I2c interface schematic why it’s not

Hi Ramu,

The bq27750 gauge is not supported by the Linux Driver for BQ27XXX, which can be accessed by this link.

Thanks,

Adam
