# dmesg | grep -i bluetooth

In spite of hci0: BCM: Patch brcm/BCM.hcd not found
the bluetooth module works:

Sometimes it is needed to run:
# rfkill unblock bluetooth
blueman works correctly.
Here https://forum.libreelec.tv/post-12512.html[dead link 2020-03-28 ⓘ] I have found a firmware for BCM43142 - BCM.hcd.
# unzip BCM.zip # cp BCM.hcd /lib/firmware/brcm/
After restart:
# dmesg | grep -i bluetooth
[ 21.606725] Bluetooth: Core ver 2.21 [ 21.606750] Bluetooth: HCI device and connection manager initialized [ 21.606758] Bluetooth: HCI socket layer initialized [ 21.606762] Bluetooth: L2CAP socket layer initialized [ 21.606771] Bluetooth: SCO socket layer initialized [ 21.663192] Bluetooth: hci0: BCM: chip id 70 [ 21.679212] Bluetooth: hci0: thinkbali [ 21.679218] Bluetooth: hci0: BCM (001.001.011) build 0172 [ 22.414606] Bluetooth: hci0: BCM (001.001.011) build 0172 [ 22.430520] Bluetooth: hci0: Broadcom Bluetooth Device (43142) [ 25.208811] Bluetooth: BNEP (Ethernet Emulation) ver 1.3 [ 25.208814] Bluetooth: BNEP filters: protocol multicast [ 25.208822] Bluetooth: BNEP socket layer initialized
But I felt no any difference without or with firmware.
Card Reader
Works out of the box. Tested with SD card 512 Mb.
Dual boot with Windows
To boot Windows 7 it is needed to switch on CSM at BIOS. Otherwise Windows boot hangs at logo. Set the BIOS setting OS Selection in the Advanced menu to Windows 7.
Freezing on 4.x kernels
Pentium N3520 processor is affected by the c-state bug: https://bugzilla.kernel.org/show_bug.cgi?id=109051
Workaround: add intel_idle.max_cstate=1
kernel parameter.
