Hi
I checked the rsapberry settings and bluetooth was not disabled. I tried disbale, reboot, then ‚enable‘ by unticking and reboot again, but still the same. I also checked the Pi model and confirmed it is a Pi3 both via both Max2Play header and also using: cat /proc/cpuinfo – see output at bottom of this post. I also looked at the overlays in the config.txt file as this seems to be where bluetooth can be disabled. It is not obviously disabled via an overlay such as pi3-disable-bt-overlay but there is a Hifiberry overlay and I also found on another forum that someone had issues when they connected devices to GPIO but no answers received. Could the hifiberry dac+ on GPIO and the hifiberry overlay somehow disable bluetooth? I am only guessing and do not know how to check!
The below are the only uncommented items in config.txt: –
# Enable audio (loads snd_bcm2835)
dtparam=audio=on
# Enable audio (loads snd_bcm2835)
dtparam=audio=on
gpu_mem=128
dtoverlay=hifiberry-dacplus
Looking at hifiberry-dacplus, only documentation I can find is: –
Name: hifiberry-dacplus
Info: Configures the HifiBerry DAC+ audio card
Load: dtoverlay=hifiberry-dacplus,<param>=<val>
Params: 24db_digital_gain Allow gain to be applied via the PCM512x codec
Digital volume control. Enable with
„dtoverlay=hifiberry-dacplus,24db_digital_gain“
(The default behaviour is that the Digital
volume control is limited to a maximum of
0dB. ie. it can attenuate but not provide
gain. For most users, this will be desired
as it will prevent clipping. By appending
the 24dB_digital_gain parameter, the Digital
volume control will allow up to 24dB of
gain. If this parameter is enabled, it is the
responsibility of the user to ensure that
the Digital volume control is set to a value
that does not result in clipping/distortion!)
slave Force DAC+ Pro into slave mode, using Pi as
master for bit clock and frame clock.
