Bluetooth does not find adaptor after overlay=pi3-miniuart-bt

Mon Dec 18, 2017 12:46 pm

Hi All,

I running into a problem with pi3-miniuart-bt. Only partial switch of UART.

My need: bluetooth enabled and adafruit gps on UART 14 15
Board: pi3 zero W
Raspbian version: latest stretch
Kernel: 4.9.59+

What have I changed:
/boot/config.txt
enable_uart=1
dtoverlay=pi3-miniuart-bt

/boot/cmdline.txt
Removed : serial0,115200

sudo systemctl stop [email protected]
sudo systemctl disable [email protected]

Rebooted

sudo apt-get install gpsd gpsd-clients
sudo killall gpsd
sudo gpsd /dev/ttyAMA0 -F /var/run/gpsd.sock
cgps -s

=> Works perfectly

HOWEVER: bluetooth: no adaptor found
sudo hcitool dev
Devices:
sudo bluetoothclt
list => nothing ...

I'm out of options ... what else can I check ??

Many thanks in advance

1. What is in /lib/systemd/system/hciuart.service?
2. Does /usr/bin/btuart exist?
3. What do get from running "ls -l /dev/serial*"?

By the way, you shouldn't have to disable the systemd getty service because it takes its cue from the kernel command line; removing "console=serial0,..." should be sufficient.
