Use simppl to access BLE advertisement messages?

[mbeltoft]

Is it possible to use simppl to call the StartDiscovery method in Bluez, and then listen for BLE advertisement messages?

[martinhaefner]

Yes, this should be possible with simppl. Calling StartDiscovery you just need a simppl Stub with appropriate object path set. I don't have any example code for this, just for advertising a BLE GATT service. Do you know how to wait for BLE advertisement messages on D-BUS? I haven't found anything in a hurry.

OK, I'll look into your code, I can see you have a stub or two there.
Yes, I have a working prototype for listening for BLE advertisement messages in "raw" D-Bus code. Decoding the messages is the problem due to all the iterators you have to go through to get to the data.

In that case, you can also just use the iterator interface to deserialize your message: DBusMessageIter iter; dbus_message_iter_init(msg, &iter); // simppl call, just add the types in the list of arguments decode(iter, bus_name, old_name, new_name); Am Mi., 9.
