question about delay in particle example

Hello,

Is it necessary to put in the delay of 500ms after "Wire.endTransmission();"?

```
// Stop I2C Transmission
Wire.endTransmission();
delay(500);
// Request 3 bytes of data
Wire.requestFrom(Addr, 3);

```
The reason I ask this is because I am using [Blynk](https://blynk.io/) and they advice not to work with delays in your code.

Thanks in advance,
Bart
