Where is iOS Bluetooth LE Peripheral Example Manager didReceiveWriteRequests

Question

I need an example implementation of the didReceiveWriteRequests function, which works on the periphery of the iOS Bluetooth, when data is written to it using the central iOS device doing "writeValue:".

But I searched the web and cannot find an example. There is still no sample code in Apple docs.

Answer 1

I have earned. Here is my working code:

// Processes write command received from a central. - (void)peripheralManager:(CBPeripheralManager *)peripheral didReceiveWriteRequests:(NSArray *)requests { CBATTRequest* request = [requests objectAtIndex: 0]; NSData* request_data = request.value; CBCharacteristic* write_char = request.characteristic; //CBCentral* write_central = request.central; //NSUInteger multi_message_offset = request.offset; // Face commands this PWR RX to advertise serno UUID? int total_write_requests = 0; if([ write_char.UUID isEqual: [CBUUID UUIDWithString: YOUR_CHARACTERISTIC_UUID]] ) { // Read desired new_state data from central: unsigned char* new_state = (unsigned char*)[request_data bytes]; my_new_state = new_state[0]; #endif NSLog(@" - advertise serno UUID: %s", my_new_state ? "TRUE" : "FALSE" ); // Select UUID that includes serno of PWR RX, for advertisements: ++total_write_requests; } if( total_write_requests ) [peripheral respondToRequest:request withResult:CBATTErrorSuccess]; // result = success else { NSLog(@"_no_write_request_FAULT !!"); } }
