I use 2 wireless boards (SENA LS100W), one MINI-ABB + SSC-32 to control legged robot.
I also use serial cable + Mini ABB + SSC-32, and the robot is working ok.
But when I use the wireless boards, the servos motors do not move at all. the communication is ok, we checked. D1 light on SSC-32 is not on at all unless I push reset button on Mini-ABB.
the DB9 port is connected 2-2 3-3 and 5-5. It used to work before.But now it doesn’t work.
Don’t post in two places. It makes it difficult to keep track. Pick one and only post there…
check Rx Tx connection, baudrate etc.
Tx from wireless should go to Rx at controller
and Rx from wireless to Tx at controller
other thing is RTS CTS signals are off etc
then check if your radios works in TTL standart just plug it directly to mega chip (if you use SSC32), but since it powered 9-30V i think RS port will be in RS232 standart so
MAX232 is required between radio and controller.
my BT module for example doesn’t want to work through MAX232 converter .
