This post builds on my previous posts in the Raspberry Pi Cluster series by adding the ability to receive data from the master. In this update, I will be adding a way for the slave to request data and have it returned by the master.
This post builds on my previous posts in the Raspberry Pi Cluster series by changing how the slave sends messages. From now on the slave will send useful information about the system to the master. The master will also be configured to receive messages of many types.
This post builds on my previous posts in the Raspberry Pi Cluster series by changing the format of the data I send. In this tutorial I am now sending data as JSON to allow a richer set of messages to be sent.
This post builds on the third step to create a Raspberry Pi Cluster Node to store our configuration settings in a config file. Here we move all the configuration settings in our script into a useful .cfg file using the python ConfigParser.
This post builds on the second step to create a Raspberry Pi Cluster Node to create a hello world application across two different scripts. Here we will create a socket connection between the two and use it to send a message to the master.
