Hi,

How to use I2C with BLE , I got return HAL_ERROR when I read/write register data from sensor.

Thanks.

Thank you for your reply.

Because my PCB assembly in production is faulty with pull-up resistors, now my problem is solved.

Please remove this question if this is junk.

Thanks,

Hello,

Are you able to use I2C without BLE using this configuration or not? If no, please refer to the I2C example available in STM32CubeWB package. If yes, check the clock configuration but I think issue is not related to BLE.

Best Regards
