I am using the MMA9555L with the nrf 51422 as master using i2c communication protocol. I have read the datasheet and sent the respective commands as mentioned there for each respective function but i am not getting the specified response from MMA9555L . An uint8_t pedo_read12[21]={0x15, 0x20, 0x00, 0x11, 0x00, 0x00, 0xff, 0xff, 0x01, 0x00, 0x00, 0x00, 0x50, 0xaf, 0x03, 0x04, 0x82, 0x05,0x00, 0x00} .This is the array sent by me as mentioned in article "pedometer configuration example" in  datasheet. Have attached screenshot of response. Any help will be appreciated.
