ModemManager: 'org.freedesktop.DBus.Error.NoReply: Did not receive a reply.'

[Thomas Bechtold <thomasbechtold jpberlin de>]

Hi,

i have a detected Modem and tried to send the SIM-PIN with the dbus 
method (with d-feet) 
org.freedesktop.ModemManager.Modem.Gsm.Card.SendPin() and get a dbus 
error back:

'org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible 
causes include: the remote application did not send a reply, the message 
bus security policy blocked the reply, the reply timeout expired, or the 
network connection was broken.'



The debug output of modemmanager (it's the latest git version, 
0c4b94458ac0a71d278ce1b711a022fdf96b3abf) is:

So the AT-Command to set the SIM-PIN worked correct, but ModemManager 
tries to send the PIN again and again and the dbus method have a timeout?!


Any ideas,

Cheers,
