Hi,
I am trying to use WL1835 bluetooth with AM335x EVM. Software is meta-arago
daisy.
When I run bluetooth agent, I get error "Can't get default adapter"
Following is the sequence of commands:
root at am335x-evm:~# bluetoothd

When I run bluetoothd, I can see org.bluez in dbus list
root at am335x-evm:~# dbus-send --system --dest=org.freedesktop.DBus
--type=method_call --print-reply /org/freedesktop/DBus
org.freedesktop.DBus.ListNames
method return sender=org.freedesktop.DBus -> dest=:1.4 reply_serial=2
array [
string "org.freedesktop.DBus"
string ":1.4"
string ":1.0"
string "org.bluez"
]
But when I query default adapter, I don't get a response
root at am335x-evm:~# dbus-send --system --print-reply --dest=org.bluez /
org.bluez.Manager.ListAdapters
method return sender=:1.0 -> dest=:1.5 reply_serial=2
array [
]
What's missing to get it working ? Any help is appreciated
Thanks
