Accelerometer no response

[EmeraldWolfram]

I am developing an android apps to read the accelerometer reading.
Pairing, setting and reading is okay for other feature - Light Sensor ....

My version is WDS112
SW: 1.5.2 (962)
HW: Rev E

I tried sending
(Set Stream Mode) 0x01, 0x06, 0xE1, 0x02 + the two CRC bytes follow by
(Enable Accel... ...) 0x01, 0x06, 0xE1, 0x01 + the two CRC bytes
and multiple try on padding 0x00 as the payload with length changes.

But the Accelerometer is not giving me respond.
Can anyone help me? or clarify the Accelecrometer Remote Protocol?

Thank you in advance.
