Bluetooth of the Macbook Pro 13 "(mid 2012) with poor signal and constant interruptions
I have a macbook pro 13" mid 2012, no retina display, with OS X 10.9.2 (Mavericks), and your bluetooth device it loses the signal when placing a barrier on the right side of the mac, the output of the optical drive (CD / DVD).
The signal is severely reduced. Just hold the Mac 's right, put my hand in front of the optical drive or turn the machine a little longer and the interference occurs.
I have a set of boxes bluetooth Sony sound and audio is constantly interrupted. I just put my hand in front of the optical drive, at a distance of about 30 centimeters (11.81 inches), and the bluetooth signal (RSSI) fell from -54dbm to -83dbm. The connection was lost completely.
Then I turned the right side of the Mac otherwise the speakers meaning and dropped signal of -54dbm to -75dBm. In this test there were no barriers in front of the optical drive. The audio suffered severe interference. The sound was inaudible.
I did other tests. The same loss occurs with the magic mouse and Apple keyboard bluetooh. Tests done in multiple locations without other nearby connections. Not occurring interference from other devices.
This is a feature of the bluetooth device mac or my computer has a hardware problem?
I thank anyone who can help me.
