IMU 6 Degrees of Freedom - v4 with Bluetooth

we have a IMU 6 Degrees of Freedom - v4 with Bluetooth and we configured the output mode to run in the wired mode. now it is sending data through the wired line but we want to change back to the blutooth mode. we tried to press the space bar while turning on the imu but it is not changing . anybody had similar problem or any ideas to solve it?

thankyou so much.

you will need to access the imu v4 via the programming serial port and change it back to the bluetooth serial port mode.
