RN4678 Transmit Power

In RN4678 Command sheet - 
The "SY <0-4>" ASCII command is used to set the transmit power level. Is 0 the highest transmit power or is 4 the highest? What are the transmit power levels associated with parameters 0-4

    Hi
    An app I made tested RSSI as following after connection
    0       -62
    1       -57
    2       -65
    3       -59
    4       -69
    Not exactly a firm answer. I saw the RSSI readings higher during some period of the connection but cant capture them. These are the final connection values

    I've done some similar tests yesterday, just to be sure about this question.
     
    But in opposite to the former values in this forum thread here, my RSSI levels were much better.
     
    Mybe the pure distance (less than a single meter beside the notebook) but probably my antenna ground plane construction (exactly as recommended in the data sheet).
     
    In a few words, RSSI values with SY,1 were mostly within -20 to -10 range (I've played a little bit with additional walls in the line of sght), and clearly increased to values between -5 and 0 with SY,4 ... :-)
     
    Cheers!
