Send and Retrieve Data

Example Code​

Pre-requirements​

Before you can send data, you will need to:

Convert Data to Bytes​

You can convert data to bytes by using the following functions from the Converter class:

Send Data​

You can use the sendData(client, tag?, data?) function to send data to a SingleNodeClient. You will need to provide a SingleNodeClient, and optionally a tag and data as bytes.

Retrieve Data​

You can use the retrieveData(client, blockId) function to retrieve data from a SingleNodeClient. You will need to provide a SingleNodeClient and a blockId. If successful, the function will return an object with the block's data.
