Same problem here.
Purchased Dobot 1.2 one month ago. Updated firmware to v1.2 successfully, put Bluetooth module into command mode and updated that successfully too.
Downloaded v1.1.1 of DobotApplication and set the baud rate to 9600 and restarted the program. Even tried setting the user input values for joints 3 and 4 to 45 as mentioned in another thread, but still no movement.
Tried moving dobot via Bluetooth on iOS, it seems like we are enable to connect because the Bluetooth light goes solid. However trying to move the dobot results in failure.
Starting to get frustrated here, so any advice would be very helpful.
