I have seen some related postings (e.g. https://stackoverflow.com/questions/13648373/bluetoothsocket-connect-throwing-exception-read-failed ), but none seems to provide a workaround for this issue. Also, as suggested in these threads, re-pairing does not help, and constantly trying to connect (through a stupid loop) also has no effect. I am dealing with an embedded device

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效，请关闭广告屏蔽插件后再试): 问题: I have code that looks like this: u := make([]byte, 16) _, err := rand.Read(u) if err != nil { return } u[8] = (u[8] | 0x80) & 0xBF // what does this do? u[6] = (u[6] | 0x40) & 0x4F // what does this do? return hex.EncodeToString(u) It returns a string with a length of 32, but I don't think it is a valid UUID. If it is a real UUID, why is it a UUID, and what is the purpose of the code that modifies the value of u[8] and u[6] . Is there a better way of generating UUIDs? 回答1: u[8] = (u[8] | 0x80) & 0xBF // what's the purpose ? u[6] = (u[6] |

I am looking for a way to extract my iPhone (OS v3.0) UUID without using iTunes. I tried "UUID Revealer" from Cydia Store but that is not working on my system.

Thanks Connect your iPhone to the Mac(mine is OS10.8). Launch System Information under Utilies the UUID of your iPhone is list under USB/iPhone/Serial Number This is super easy on Windows. You can also go to Control Panel > Devices and printers in win 7. Plug in the phone Device Manager >

Code excerpt: // CREATE SPP SOCKET mSock = device.createRfcommSocketToServiceRecord( uuid ); if( mSock == null ) { return( -1 ); } // TRY TO CONNECT mSock.connect(); The code above works fine Android-to-Android. Linux on the other hand requires just an "rc channel number" (an integer). The following is some sample code

Does Delphi have anything built-in to generate UUIDs? Mitch Wheat program Guid; {$APPTYPE CONSOLE} uses SysUtils; var Uid: TGuid; Result: HResult; begin Result := CreateGuid(Uid); if Result = S_OK then WriteLn(GuidToString(Uid)); end. Under the covers CreateGuid() calls one of the various APIs, depending on the platform. For example on Windows, it nowadays calls UuidCreate . Nat Also, if you need a GUID for an interface declaration, hit ctrl + shift + g in the code editor to insert a GUID at the caret. RBA If you're using one of the latest version of Delphi, and include SysUtils, you can call
