thanks for the help. Anyways, as the title says I have the Broadcom43142 chip for Wifi & Bluetooth. It is a dual-chip, it contains both WiFi and Bluetooth. *Groans Here is the output from dmesg | grep -i blue

I found a solution.

You need to search for a .hex file from a Windows installation, I found mine in C:\Windows\System32\drivers\BCM43142A0_001.001.011.0197.0231.hex; find the one that starts with BCM43142A0.

Then you need to convert it to hcd format. You can find the tool at https://github.com/jessesung/hex2hcd.

git clone git://github.com/jessesung/hex2hcd.git
cd hex2hcd
make
hex2hcd <input_file>.hex fw-xxxx_yyyy.hcd

Insted of fw-xxxx_yyyy.hcd you should use BCM43142A0-0a5c-21d7.hcd.

Then copy the generated hcd file to /lib/firmware/brcm/ and restart.

That should fix the issue.
