hi
we are using mpu9250 and nrf51 to develope a ble device. We need to use 9 axis mode to measure a, g and m. But the current consumption when the chip is in sleep mode is too high. I set MPU_REG_PWR_MGMT_1 to 0x40 and set magnetometer mode to 0 to make the whole chip to sleep. Is this method right?
I get 1.2mA after set the chip to sleep. It's still too high and the specification says it will only be 8µA. Is there any thing I do wrong? Thank you !
