Thanks for getting back to me on this Tim, *pauses pulling his hair out for
a moment.
I'm back on this damn API and its driving me crazy I get three options
really for returning a service record from the API, they look like this.
array{uint32} GetRemoteServiceHandles(string address, string
match)
This method will request the SDP database of a
remote
device and retrieve the service record handles. To
request service browse send an empty match string.
Possible errors: org.bluez.Error.InvalidArguments
org.bluez.Error.InProgress
org.bluez.Error.ConnectionAttemptFailed
org.bluez.Error.Failed
array{byte} GetRemoteServiceRecord(string address, uint32
handle)
This method will request the SDP database of a
remote
device for a service record and return the binary
stream of it.
Possible errors: org.bluez.Error.InvalidArguments
org.bluez.Error.InProgress
org.bluez.Error.Failed
string GetRemoteServiceRecordAsXML(string address, uint32
handle)
This method will request the SDP database of a
remote
device for a service record and return its data in
XML
format.
Possible errors: org.bluez.Error.InvalidArguments
org.bluez.Error.InProgress
org.bluez.Error.Failed
The first method, when I print its results just gives me
dbus.Array([dbus.UInt32(65547L)], signature=dbus.Signature('u')) the method
gives me that byte array and the third doesn't appear to work at all :-D
Unfortunately nowhere seems to document what exactly those arrays contain,
so I'm trying to crack one open and find out, but as you can see, I'm not
having much luck. Perhaps this is a DBus thing, they do have a mailing list
so I'll give them a go in a while.
If you have any brain waves let me know mate, I'll add another beer to the
tab,
Rob

No idea, but what happens when you iterate over it?
for i in array_thingy:
print i
Or does it support the buffer interface?
for i in buffer (array_thingy):
print i
If it did then you can at least get access to its
innards and construct some kind of string representation.
I've no idea what the numbers are supposed to represent,
so I don't know what "convert it to a string" is likely
to imply. This looks rather more like a dbus question than
a strictly Python one. Is there a DBus mailing list or
what-have-you?
