    `let value = myCharacteristic.value`. Now, what's supposed to be " <500c0b62 00008f2c 10223344 55660000 00000000>"? What is it supposed to mean? Is that a "text"? A custom struct you send? We can't guess how to parse it without infos of the specs of your peripheral. – Larme Dec 05 '18 at 09:32

    `let value = myCharacteristic.value`. But `<500c0b62 00008f2c 10223344 55660000 00000000>` is more a debug value, you can get it with `print("\(value as NSData)")`, but printing hex data seems weird. You can check https://stackoverflow.com/questions/39075043/how-to-convert-data-to-hex-string-in-swift for the hex representation. – Larme Dec 05 '18 at 09:40

Try this 

if(characteristic.value != nil){
            if let ASCIIstring = NSString(data: characteristic.value!, encoding: String.Encoding.utf8.rawValue) {
                characteristicASCIIValue = ASCIIstring
                print("Value Recieved: \((characteristicASCIIValue as String))")

            }
        }

  • Please don't do `if(characteristic.value != nil)` and then `characteristic.value!`: instead, directly safely unwrap with "if let", it's much better and swifty. – Eric Aya Dec 06 '18 at 13:06
