It is also possible to change the Baud Rate, data bits, parity, stop bits and flow control values.
To get the latest updates to the BB-PMU and BB-Serial packages, type in the following commands in your terminal:

$ apt-get update

The latest version of Node-RED contains a new flow allowing the user to connect to different cloud services. This cloud connector flow will allow you to connect the BB-400 to the following cloud services: AWS (Amazon Web Services), IBM or FRED (Front End for Node-RED).

The flow also reads the BB-400’s IO status using WebSocket, then sends the IO status to the cloud services. The device can also receive data from the cloud services.

Node-Red Flow

This flow will appear in your Node-RED flow if you run the following commands:

$ apt-get update

$ apt-get install bb-node-red

Restart your Node-RED instance, then import the cloud connector example by clicking on the menu and going to:

Import > Examples > Brainboxes > CloudConnectors
