I want to know how connection is established between my BB phone and BES?
Is connection based on my mobile service provider or some other thing?
Can u tell me ,how is this?
Usually a Blackberry is used in a corporate environment. Using the Blackberry MDS Dataservice a connection looks like this. The datastream is encrypted and compressed.

For a quick overview I recommend this video by Research in Motion.
Network Transports
The connection between a Blackberry and the BES can be carried over the wireless carrier network, to the internet, to the RIM operations centre then by the internet to the BES; or by Wi-Fi to the internet to RIM to the internet to the BES; or by Wi-Fi directly to the BES (if the BES is local to the Wi-Fi connection); or by USB to a PC with Desktop Manager via the local area network to the BES.

I need to enable multiple devices to communicate with each other using OSC protocol which runs over IP protocol etc.
I have two wireless routers, one of them is capable of providing internet access from SIM card.
What I want to accomplish is:
provide all devices wireless connection for communication between each other
provide all devices connection to the Internet
avoid spending data from SIM card when my devices communicate with each other
This last point is what I can't solve - in my mind it should not be a problem. If I understand it correctly, I am creating a WLAN and there is no need for passing the data to the internet provider (or asking for data from him) and the router should act like a switch and route the signal from one device to another one if the IP and port is correct.
I have router TP-Link Archer C6 ; router TP-Link Archer MR200 ; Windows laptop ; Android phone ; iPad.
What I want to accomplish is remote control of DAW Reaper (running on Windows laptop) over Web Control Surface or OSC Protocol with TouchOSC app or Open Stage Control app.
I will appreciate any help!
Thank you very much in advance,
Peter
Maybe this is a stupid question but..
Are Wi-Fi Direct and Wi-Fi P2P the same thing?
And I mean, the EXACTLY same thing?
I'm getting really confused with this two.
Wifi Direct is a technology for peer to peer connections and is very different from wifi. Wi-Fi Direct, initially called Wi-Fi P2P, is a Wi-Fi standard enabling devices to easily connect with each other without requiring a wireless access point.It is usable for everything from internet browsing to file transfer
Wifi Direct is not same as wifi . On Jelly Bean and above, when you try to use the WifiP2pManager API, WiFi-Direct is automatically enabled (as long as WiFi is on). Wifi can be switched on by calling:
WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE); wifiManager.setWifiEnabled(true);
For ICS refer to this Can I turn on WiFi-Direct from code? on Android API-14 (ICS)
This is the main reason to get confused between the two.
How do we programatically detect whether the BIS data traffic is routed through the carrier network or Wi-Fi. Looking at the BB logo dots, we can see that it will be near Wi-Fi indicator if data is routed through Wi-Fi, and near the carrier signal indicator if the data is routed through the carrier data network.
Is there a way to detect that programatically?
You can use the API to determine if a particular service is capable of carrying BIS-B or BES traffic. Since BIS-B and BES are automatically routed through the least expensive means, if Wi-Fi is capable of carrying it BIS-B will go by Wi-Fi.
The KB article in Mister Smiths's comment specifies BIS-B access is available with a qualifying data plan (AKA a BlackBerry data plan, BlackBerry bolt on, etc
"To connect to the BlackBerry Data Services over Wi-Fi for PIN
messaging and BlackBerry Internet Service connectivity, the BlackBerry
smartphone requires a BlackBerry data plan from the wireless service
provider..."
). Given a qualifying data plan BlackBerry Internet Service (BIS) is available under all conditions specified in the chart. If the Wi-Fi connection supports a connection to the BlackBerry router at the ROC then BIS will travel via that connection unless a better option is available. One such better option is also known as "wireless bypass". When a BlackBerry in connected (by USB or BlueTooth) to a PC with internet access and Desktop Manager installed, the BlackBerry will use the PC internet connection.
The KB article also mentions BES. It is often helpful to think of BIS/BIS-B as a subset of BES capability hosted at a RIM Operations Center. Both BES and BIS/BIS-B make use of the BlackBerry router capabilities. The BlackBerry will automatically seek out the apparent least cost method of connecting with the BlackBerry Router either BES or BIS/BIS-B. In order of preference that is: wireless bypass; Wi-Fi; wireless carrier.
Try disabling Wi-Fi:
Radio.deactivateWAFs(RadioInfo.WAF_WLAN);
Maybe you could also detect if Wi-Fi is active calling RadioInfo.getActiveWAFs, but how would you know if it is your app the one using the connection?
To detect whether BIS is going through Wi-Fi, use
if (CoverageInfo.isCoverageSufficient(CoverageInfo.COVERAGE_BIS_B)) {
if (CoverageInfo.isCoverageSufficient(CoverageInfo.COVERAGE_BIS_B, RadioInfo.WAF_WLAN, false))
{
//BIS-B going through wifi
}
else
{
//BIS-B going through carrier
}
}
Has anyone researched how to access the gps chipset on a blackberry over usb so that it is unnecessary to transmit this data over the cell carrier's data network?
Is it possible to access the GPS chipset, store information in a buffer, and open an interface connection (over the usb charging port), for access? Not sure if J2ME allows for this...
Checkout the "UsbDemo" project and the "GPSDemo" that are included in the blackberry JDE.
the GPSDemo listens to the GPS and stores the location information into a buffer that gets sent over the network.
The USB Demo shows how to interact with a desktop client over USB.
You should be able to pull on the network code from the GPS Demo and put in the the code to talk over USB.
Wondering how to connect blackberry to desktop or the other around via tcp/ip? I assume both the desktop and the blackberry are connecting to the same router.
If I read your question correctly and you want a TCP connection over a WiFi router on the same LAN as your desktop, then from your BlackBerry app you simply do:
javax.microedition.io.Connector.open("socket://<your desktop's IP/hostname>:<port>;interface=wifi");
(you can replace socket:// with tls:// ssl:// for a TLS or SSL3 socket connection)
If you're going over the cell network the situation is a bit more complex - you'll only be able to connect to your desktop if your device is attached to a BES on the same LAN as your desktop, or if your desktop has a public IP, but the basic syntax is the same (minus the interface=wifi obviously).
