Pi 3 - no wifi or bt ?

Sat Mar 12, 2016 4:08 am

I had a Pi 2 and before moving the SD card to a new Pi 3, I did:

Code: Select all

apt-get update
apt-get dist-upgrade
rpi-update
reboot
So far as I can tell, everything on the 3 looks as it should, but I don't see any evidence of the BT or Wifi.

Is there another step required to get them to show up?

Are you using dtoverlay=sdhost to overclock?

If so, change it to dtparam=sd_overclock=100

My config.txt has no dt lines in it at all.

Code: Select all

# grep -v ^# config.txt
hdmi_force_hotplug=1

hdmi_group=1
hdmi_mode=4





gpu_mem=64

max_usb_current=1

Try, from a command line:

Code: Select all

hciconfig -a
That should tell you that the Bluetooth adapter is recognized and powered up.

I had to install bluez and bluez-hcidump, but having done that, hciconf -a prints nothing.

This post:

viewtopic.php?f=28&t=138137

has the solution. Two files are missing from /lib/firmware/brcm. I was able to fill in the missing files from

https://github.com/RPi-Distro/firmware-nonfree

At least, that made wlan0 show up. hciconfig -a still shows nothing.

I figured out BT.

I was unable to add pi-bluetooth, because wheezy doesn't have that package, but upgrading the whole system to jessie made it available. That pointed out that what was apparently missing was "bluez-firmware". Now hciconfig -a shows the local host adapter, and I can see some local BT devices with an hcitool scan.

Anyone know where to obtain the firmware needed for bluetooth? Fedora doesn't have a "bluez-firmware" package. I've posted in another post here about it.

I seem to have the same issue as nsayer with hcitool / hciconfig not showing anything.
