Details/sequence/order of allocate_client calls? Allocate client for WDA fails...

[Martin Maurer]

Hello,

I have a question about allocating clients. I use this (based on python 
example in repo):

def open_ready(qmidev,result,user_data=None):
     print("open_ready")
     try:
         qmidev.open_finish(result)
     except GLib.GError as error:
         sys.stderr.write("Couldn't open QMI device: %s\n" % error.message)
         main_loop.quit()
         return

     qmidev.allocate_client(Qmi.Service.DMS, Qmi.CID_NONE, 10, None, 
allocate_client_DMS_ready, None)

     qmidev.allocate_client(Qmi.Service.WDA, Qmi.CID_NONE, 10, None, 
allocate_client_WDA_ready, None)

     qmidev.allocate_client(Qmi.Service.WDS, Qmi.CID_NONE, 10, None, 
allocate_client_WDS_ready, None)


This gives me:


open_ready
allocate_client_DMS_ready
allocate_client_DMS_ready: successful
CID 4
allocate_client_WDA_ready
Couldn't allocate QMI client WDA: QMI protocol error (3): 'Internal'
device_close
device_close_ready
Query done
allocate_client_WDS_ready
Couldn't allocate QMI client WDS: CID allocation failed in the CTL 
client: Transaction timed out


I am using:

Why it fails to allocate a simple WDA client? Does it need more, so that 
I can allocate it successfully? Or order important?

And even when it fails, why does WDS fail afterwards?

When I comment out "WDA" it behaves correctly:

open_ready
allocate_client_DMS_ready
allocate_client_DMS_ready: successful
CID 5
allocate_client_WDS_ready
allocate_client_WDS_ready: successful
CID 21

Or do I need to wait for an answer from this

qmidev.allocate_client(Qmi.Service.DMS, Qmi.CID_NONE, 10, None, 
allocate_client_DMS_ready, None)

before calling

qmidev.allocate_client(Qmi.Service.WDA, Qmi.CID_NONE, 10, None, 
allocate_client_WDA_ready, None)  ?


PS: How can I query used libqmi version in Python?

PS2: And how I can I enable debug (like -v) in Python? Some Python call? 
Or must I use some environment variable?


Many thanks!

Best regards,

Martin
