For a simple call like Get Manufacturer, see e.g:
http://www.lanedo.com/~aleksander/libqmi/html/libqmi-glib-DMS-Get-Manufacturer.html

So the flow would be:
 * Create a QmiDevice.
 * Request to allocate a QmiClient for service QMI_CLIENT_DMS.
 * Call the get_manufacturer() method in the QmiClientDms.
 * Get the response with the output bundle in get_manufacturer_finish().
 * Check about errors in the bundle with output_get_result().
 * Get the final string if no errors with output_get_manufacturer().

For each async operation, both the call and finish() use bundles to pack
all possible input or output TLVs, so the bundles will also need proper
introspection data.

I guess the same flow would apply in the case of a Python client. From
what I can tell, the generated sources need additional annotations for a
proper introspection (think I added some I knew of, but probably not
all); or you won't be able to run the previous flow.

I would suggest to play with all this first, including:
 * operations that need TLVs in output bundles
 * operations that need TLVs in input bundles
 * operations with different input/output types being passed (e.g. with
integers, strings)
 * operations with different containers (e.g. structs, arrays)
