Proximity Sender - Some connections status ignore
« on: December 28, 2009, 05:58:11 PM »
Hi,

i'm trying WCL Proximity Sender Personnal edition, 6.7.0.0 (demo version).
During my tests many devices (phones) found return send result as WCL_E_TIMEOUT (43),
but at the same time nothing append on phone's screens : i expect a message like "would you like to receive file XX from computer XX ?" - "YES" / "NO"

- i tried change connection timeout to 60, without more success

- i tried also with "BluetoothOPPClientDemo" and when i use "connect" on phones, the result is "timeout", but the phone never react.

- then i tried with "TextBlue" app' but i got same result.

I can't make an exhaustive list of incriminated phones.
Have you got some explanations about that ?

My bluetooth driver is Microsoft stack (Enum MS Bluetooth version = 6.0.6000.16682)
The library used is "Personnal WCL 6.7.0.0" for .NET

Thank you for your answers.

Are you able to send file to your device with using standard windows BT tool?

Proximity Sender - Some connections status ignore ...

I didn't try that : i'll do.

Until next test,
do you know some restrictions made by phones' constructors on bluetooth obex service ?
For example on my phone : Sony Ericson K750i i have no connection timeout problem.
For another phone like HTC H2 i have a timeout connection problem and no reaction on phone.
Another example on Acer phone (F900) it seem that i have same timeout if phone is in sleep mode, not if phone is awake (screen light on)

i'll post my next tests tomorrow.

Proximity Sender - Low-level error
« Reply #4 on: December 29, 2009, 05:52:29 PM »
Hi,

this afternoon i tried normal push object from my phone to another phone in sleep mode.
Then he didn't awake, like with wcl library, and my phone said he can't connect.

I made an update on my Windows Vista : got SP1.
Now, with wcl library (with 60 sec. timeout) i have a "Low level" error in ProximitySender app' where i had "Timeout" error before.
I read you post about "low-level driver internal error" (http://forum.btframework.com/index.php/topic,775.0.html)
But i don't know how to change manifest, when i publish debug mode (visual studio 2008) manifest is rewritten.

How could i know if my Microsoft Bluetooth drivers use widcomm or are native ?

Another question, do you know some tricks to force phone awakening before sending my files ? Maybe Obex is not the best way ?
Could it be a problem from Bluetooth version (2.1) into phones ?

Thanks a lot for previous and next anwers.

Hi,

Manifest

WidComm: Actually there is no WidComm drivers on Vista/Win7. It can be just extension for MS drivers. So it can be only MS/BlueSoleil or Toshiba.

Phone: Unfortunatly there is no way to wakeup phone from PC if phone does not support such feature.
