HC 05 Bluetooth sends wrong distance to android when uused along with HC SR 04

I am using a Arduino UNO board I plugged in an Ultrasonic sensor (HC SR 04) and a bluetooth module (HC 05) I measure distance using the Ultrasonic Sensor and transmit it to android. The problem is I am receiving wrong random distance values. For example the height of ceiling from my desk is 215cm I am receiving random values between 40 and 60 cm. I checked the serial output of arduino without bluetooth and it displays correctly but with bluetooth output is wrong. please help out I am a newbie.

It may be a baudrate mismatch, or a wiring problem.

Have you checked the serial output WITH bluetooth?

It might be time to cease being secretive about the code, and some comment about the power supply might be helpful. Whatever the problem might be, bluetooth is innocent.
