The BFObjectPushClient Object

For this you use the BFObjectPushClient as the simple approach. In this method you open the connection, send a file and close the connection. Your program will also get events on the progress.

The progress events are as follows:

• OnData
• OnDisconnect
• OnProgress: There is an ?Abort? parameter which will stop the transfer if set

Using this object to send a file is quite straightforward:

Sample: Send a file

Code: [Select]

    BFObjectPushClientX1.BluetoothTransport.Address = strDeviceAddress
    BFObjectPushClientX1.Open

    Debug.Print "Connected with " & BFObjectPushClientX1.BluetoothTransport.Address & _
        ". Service: " & BFObjectPushClientX1.BluetoothTransport.Service
    BFObjectPushClientX1.Put "C:\Temp\me.jpg"
    BFObjectPushClientX1.Close
As mentioned above, the OnProgress event will be fired multiple times showing how much of the file has been sent. You can change the ?Abort? parameter to stop sending a file.

5.2 changes

Since 5.2 version Bluetooth Framework supports multi APIs. It mean, you should specify which Bluetooth dongle (radio module) the library must use to send file.

BFObjectPushClientX (as well as all other components which has BluetoothTransport property or which designed to use with Bluetooth (such as BFBluetoothCOMPOrtCreator)) now has Radio property.

Code: [Select]

BFObjectPushClientX.BluetoothTransport.Radio
How to specified the working radio? It is very easy. Firstly, you can use BFBluetoothDiscovery to enumerate installed radio modules and then assign one to this property. (See http://forum.btframework.com/index.php?topic=182.0 for more details)

Code: [Select]

BFObjectPushClientX.BluetoothTransport.Radio = Radio
Secondly, you can just assign selected (discvoered) device to Device property

Code: [Select]

BFObjectPushClient.BluetoothTRansport.Device = Device
If you are using BFObjectPushClient with other transport (not with Bluetooth) you do not need specify radio.

Also, you can refer to following topics (about radios and MultiAPIs(tm))

Mike

Thanks. I shall update my document. As I said, I hadn't proof-read what I had written. I had posted the snippet here from my main Word document where I am documenting all the classes and how to use them to show people what I've been doing.

My original code had been written using BTF 5.1.5. I have been changing the code for 5.2.0.

The problem is that I had no idea just how much stuff I would have to write. I really need other volunteers to help me. People, step forward please.
