ROS and DBus : Advertisement.GetAll not a Python function
Hello everyone,
Hope you're doing good. It's my first post on ROS topic, I hope you could help me with an error I got when I run my launch file. I'm using python-dbus in order to make a bidirectional communication between a BLE device and a BLE peripheral. I use the bluez example of gatt-server and example-advertisement
I'm using python 2.7 with bluez 4.3 and I got an error when I compile my file with the dbus.service.method you can find on line 99 of example_advertisement.
@dbus.service.method(DBUS_PROP_IFACE,
in_signature='s',
out_signature='a{sv}')
def GetAll(self, interface):
print 'GetAll'
if interface != LE_ADVERTISEMENT_IFACE:
raise InvalidArgsException()
print 'returning props'
return self.get_properties()[LE_ADVERTISEMENT_IFACE]
The output error is :
TypeError: <cyfunction Advertisement.GetAll at 0x76188d30> is not a Python function
If anyone knew how to solve this problem, I'll be grateful for life !
