Serial Bluetooth, sending and recieving data question


I have a simple question on using the serial Buetooth LE. The master has the correct MAC and the terminal

I am using says all the information that was entered is correct and I am not getting any errors.

My question is when I enter data to be transmitted ( ATS10=1 ). When I pressed ENTER it is transmitted

with no errors.

Is the data I am entering into the master to be sent ( ATDS10=1 ) slave when enter is selected. Is the

slave receiving (1)? And when I ask to see register 10 ( ATDS10? ) am I seeing data from the slave or

am I just seeing data that I entered into register 10 of the master.

I hope this is understood.
