"^ECHOF 1" problem with ttl microcontroller comunication 1 Year ago  
hello, i'm using a micro-controller to send and read commands from my SDC2130-S controller.
when ECHOF is set to 0, everything works great, i can send command and queries and read the echos.
when i turn the echo off (^ECHOF 1) and then try to send commands nothing happens and the controller echo junk.
i noticed that when a script is running i can read its printings well.
when using the roborun+ program with usb connection i can turn off the echo with no problems.
here is an example of the controller echos before and after the echo off command:
"
!g 100
+
!g 200
+
?c
C=290860:0
^ECHOF 1
+
kkkkkkk‚kkkkk‚‚kkkkk
"
my goal is to control my motor with my micro-conroller without getting commands acknowledgements. i want only to transmit a specific data from the controller to the mc.
can anyone help with this problem please?

thank you,
Yam Geva

Echo off is practically never used by anyone. We'll verify that it works.

In any case, echo off would not eliminate the + and - acknowledgement. It would only eliminate the controller from sending back every character it receives.

For your application, you may find it just as simple to ignore the echoed characters.
