How to run two vesc motor's in different direction over bluetooth uart data

i am using two vesc4.12 connected over CAN and with master i connected bluetooth. i want to rotate both motor in different direction.

when i send 255 at x and y value. both go forward , and on 0(zero) both go backward but when i send 255 on x and 0 on y in that case also rotate in same direction.

can anyone plese tell to rotate both motor in different direction what data should i send and what setting should i do

complete data format which i am sending over bluetooth.{2,11,35,255,255,0,0,0,0,0,0,0,0,51,185,3}

If you run unsensored just swap motor phase wires to change direction.
