Cannot write_value twice through BlueZ

[Slievenamon]

Hi, I'm using BlueZ 5.50,
When I send value through BlueZ, it's work properly the first time but when I call the function a second time the dbus send me back an error (InProgress):
write value failed
write value fail for characteristic 6e400002-b5a3-f393-e0a9-e50e24dcca9e , error, In Progress
write value succeeded
write value succeeded for characteristic 6e400002-b5a3-f393-e0a9-e50e24dcca9e

my code :
characteristic_tx.write_value(str)
time.sleep(10)
characteristic_tx.write_value(str)

Do I need to send something to clear BlueZ flag ?

I'm not used to Python, how can I generate interruption in GObject.MainLoop() to send data through BlueZ ?
