I have an acer Aspire E3-112 which has internal Bluetooth ... I am unable to get it working ... it seems the only drivers available are for Windows. So I inserted a logitech USB Bluetooth dongle; now Ubuntu 14 is able to 'see' the device (my iphone 5) sometimes, but even with Ubuntu finding the device the connect function is greyed out.

Any help would be appreciated. Thanks - Trenton

I downloaded the Windows driver and found the following: %Dell1704.DeviceDesc%=RAMUSB21D7, USB\VID_0A5C&PID_21D7 ; BRCM Generic 43142A0 RAMUSB

I can not find the *.hex file that the other posting is asking for. Please help.

Just found it ... following further directions from previous question now.

how do i "Now extract that firmware from the same cab file." ??

I am a newbie, sorry for any extra effort .. I am following the directions in the other post.

I found the file BCM43142A0_001.001.011.0197.0229.hex ... what does it mean when the instructions say "Now extract that firmware from the same cab file."?

I believe I have done all the steps in the preceeding issue ... here are some commands I saved to make sure I did it correct: %BtUSB.DeviceDesc%=BlueRAMUSBE055, USB\VID_0489&PID_E055 ; 43142A0 Acer combo

BCM43142A0_001.001.011.0197.0229.hex

sudo cp BCM43142A0-0489-e055.BCM.hcd /lib/firmware/brcm

Does that look correct?

BCM43142A0-0489-e055.BCM.hcd is that wrong?

Yes, you are right about BCM43142A0 device. I think you take incorrect *.hex file. You can find required firmware from here - https://github.com/winterheart/broadcom-bt-firmware . Make sure that you placed *.hcd to /lib/firmware/brcm. After that re-insert BT device or just reboot.
