I'm trying to use "Bluetooth HCI snoop log" on my Nexus 6P with Android 7.1.2 but even if the option is enabled in the developer option it doesn't work. In fact, the option inside the bt_stack.conf is disabled.
adb shell head /etc/bluetooth/bt_stack.conf
# Enable BtSnoop configuration from this config file
# Snoop is enabled by default on userdebug builds, below configuration
# enables to override it and take effect from the configurations here.
BtSnoopConfigFromFile=false
# Enable BtSnoop logging function
# valid value : true, false
BtSnoopLogOutput=false
BtSnoopExtDump=false
Anyone has encountered this issue?
