Key Features CoreBluetooth CBATTErrorDomain Code = 11 "Attribute Not Long

Question

I have a characteristic value that contains a large data set (~ 200 bytes)

Peripheral

_ch = [[CBMutableCharacteristic alloc] initWithType:_chUUID
                                      properties:CBCharacteristicPropertyRead
                                      value:nil                                                                 
                                      permissions:CBAttributePermissionsReadable ];

When this value is requested, the didRecieveRequest callback is called:

-(void) peripheralManager:(CBPeripheralManager *)peripheral didReceiveReadRequest:(CBATTRequest *)request {

if ([request.characteristic.UUID isEqual:_chUUID]) {
    if (request.offset > _data.length) {
        [_peripheralManager respondToRequest:request withResult:CBATTErrorInvalidOffset];
        return;
    }
    else {
        // Return the data
        request.value = [_data subdataWithRange:NSMakeRange(request.offset, _data.length - request.offset)];
        [_peripheralManager respondToRequest:request withResult:CBATTErrorSuccess];
    }
}

This is pretty much the case for Apple.

On the central side, when the callback is called didUpdateValueCorCharacteristic:, I get an error

Error Domain=CBATTErrorDomain Code=11 "The attribute is not long."

I know that I could use the Notify mechanism to crop the data myself, as shown at WWDC 2012. But this is not an option, because I am not responsible for the central code.

I would suggest that it didReceiveReadRequest:should be called more than once (with an increase in offset), since the CB Framework should take care of the block, right? Am I missing something here?
