i use SKKCA-21 for transmitting the ASCII code to control two motors direction
w forward 1010
s backward 0101
a left 1000
d right 0010
x stop 0000

the connection is up...in bypass mode...sending 'w' and the motors is moving forward...but when sending 's' the motors doesn't move and the connection is down

AT-ZV ConnectionUp
AT-ZV -BypassMode-

w

s

AT-ZV -CommandMode-
AT-ZV ConnectionDown


i coudn't figure it out why? but b4 trying with the motor i use 4 LEDs...the LEDs are fine... so what happen with the motor?

plus when the motor is block from moving ...the connection is down 2...

Maybe the current draw higher when motor is blocked which cause the system reset. For reverse, you need to troubleshoot the hardware. Try change the motor wires polarity and press forward, just want to make sure the motor can 'reverse'. If not OK, then the reason same as motor blocked. If that OK, then check the hardware part at motor driver. What you need is check, check and check, that is called TROUBLESHOOT. :)
