bytearray - Objective- C how to send data with a Byte Array using Core Bluetooth -

-

I'm trying to send Affes type type through the core Bluetooth will be able to access any other device and use Will be able to. @ Implementation NeeAppDelegate typedef struct {float a, b, c, 

  four names [20]; } MyObject;   
 So here I have declared my typedfaf class, which I want to send through core Bluetooth, which I think is okay. Then in a method later:  
  - (zero) method} type myObject type type; // put it in a byte array _bitere = (byte *) and in the object; Set all the cans in the 0 array (and object, 0, psychobt) in the array; // Assign values ​​to my object myObject.a = 1; MyObject.b = 2; MyObject.c = 3; // This value can be changed, so I have set 20 NSString * name = @ "Name"; Strcpy (myObject.Name, [name UTF8String]); _bitdata = [NSDTO alloc] Init Withbits: _BiteArere Length: SizeOf (MyObage)]; }   
 Now I switch classes to a peripheral ViewController where I handle sending data  
  - (zero) peripheralManager:. (CBPeripheralManager *) Peripheral Union (Sibisiantrl *) Central subscribe by Hanrokarnististik (CBC Features *) feature {if (m_dataToSend! = Null) {[m_dataToSend release]; } M_dataToSend = [NeeAppDelegate Shared Instance] .byteData; M_sendDataIndex = 0; [Send yourself the data]; }   
 Here dataSend method I used to send data to another device  
  - (minus) sendData {if (m_sendDataIndex & gt; = M_dataToSend .length) // Is anyone on the left to send? {// No data left EOD message [M -priferl Manajr Apdetvolum [Ansdita data] to Lisinektiv: M_tronsrprsirtestistik on Sbskripted Sentrls: Nile]; [M_preferl manager closed ad]; // Beacon advertising Resume [_viewControllerNeedle.needlePeripheralManager startAdvertising: _viewControllerNeedle.beaconSpecificPeripheralData]; } And {BOOL bDidSend = YES; NSITferer zodiaced = 0; // left the data, so send the callback until the failure, or we have done it. While (BDaidend) {amountToSend = m_dataToSend.length - m_sendDataIndex; If (amount Tosend & gt; NOTIFY_MTU) {amountToSend = NOTIFY_MTU; } // data we want bDidSend = copy out [m_peripheralManager updateValue: [NSData dataWithBytes: m_dataToSend.bytes + m_sendDataIndex length: amountToSend] forCharacteristic: m_transferCharacteristic onSubscribedCentrals: nil]; If (bDidSend) {m_sendDataIndex + = amountToSend; }}}   
} 
 
 How can I get access to data within the BITE array now in my Central Manager class? I know that you must know the format to the value of a byte array used to 
 
  * (float *) and [NeeAppDelegate is sharedInstance] .byteArray [0]; The text is the easiest way to checkout ->  
 its text Next, use this code (to be all things controlled by LGBluetooth, even connections)  
 LGUtils writeData: self.transactData charactUUID: FCBBLEPaymentTransactionCharUUID serviceUUID: FCBBLEPaymentServiceUUID peripheral: APeripheral completion: ^ (NSError * Error) {}];  
 Here is a sample code, which will convert NSString to equivalent NSData  
  NSString * someString = @ "123456789"; Const char * transactStr = [someString UTF 8 string]; Int8_t * transactbytes = malloc (strlen (transactStr) * sizeof (int8_t)); Size_t transactDataSize = (strlen (transactStr) * sizeof (int8_t)) / 2; Int cursor offset = 0; For (int i = 0; i & LT; transactDataSize; i ++) {transactBytes [i] = ((transactStr [curssorOffset] - '0') * 16) + (transactStr [curssorOffset + 1] - '0' ); Cursor offset + = 2; } NSDTA * TransdataData = [NSDTATA DataWithbites: TransActivity Length: Transdetectus]; Free (transactBytes); [LGUtils writeData: transactData charactUUID: @ "5ec0" serviceUUID: @ "4ca1" peripheral: APeripheral completion: ^ (NSError * Error) {aCallback (error); [Aperifier disconnectivity finale: zero]; }];

java - Gradle dependencies: compile project by relative path -

Is it possible to specify a dependency on another gradeal project in the granular (in android studios) outside the current project limits? For example, with a relative path like this: dependence {collection project ('../../ stdlib / dagger'}} MyApp (path / user / foo / workspace / mypad) The app (Path / User / Foo / Workspace / MyPass / App) And I have an Android Library Project with 3 subdomules: stdlib (path is / user / foo / Utilities (Path / User / Foo / Workspace / Stadlib / Utilis) http (Path / User / Foo / Workspace / Stadlib / HT) / Li> What I have to do is compile the Dagger, Util, http module in the MyApp project. The Stidelib Library module under heavy development And MyApp will grow in the form of Growth, so I do not want to push them into a Mewen repository. I am a little change. is likely to add another Gredle projects in some way? I will push the study library into the Maven repository after the source is in search of a temp...
