Its iOS app using Nordic type app with custom framework. While a tried to update 3 character then only it crashed. I was able to update single character successfully... like date

written code:

let bytes : [UInt8] = [ 0x00, 0x09, 0x98 , 0x88, 0x83, 0x92, 0xD3, 0x39, 0x39, 0x39, 0x39, 0x39 ] let datar = Data(bytes:bytes) deviceNameCharacterToUpdate?.service.peripheral.writeValue(datar as Data, for: deviceNameCharacterToUpdate!, type: CBCharacteristicWriteType.withResponse)

    let bytess : [UInt8] = [ 0x43, 0x67, 0x61 , 0x6E, 0x64, 0x72, 0x61, 0x20 ]
    let dataLoca = Data(bytes:bytess)
    locationCharacterToUpdate?.service.peripheral.writeValue(dataLoca as Data, for: locationCharacterToUpdate!, type: CBCharacteristicWriteType.withResponse)

    
    let data = self.dataWithHexString(hex: hexDateToWrite)
    dateCharacterToUpdate?.service.peripheral.writeValue(data, for: dateCharacterToUpdate!, type: CBCharacteristicWriteType.withResponse)
