Welcome to the June 2019 update for the BB-400.

This version of software has implemented changes to the following 3 packages:

• BB-PMU
• BB-Serial
• Node-RED

BB-PMU

There has been a performance enhancement update within the BB-PMU (Power Management Unit) package. The device can now recover from UPS mode without restarting.

BB-Serial

The following serial configurations are possible:

• Full Duplex: RS232, RS422 and RS485
• Half Duplex: RS485

Switching between serial configurations is possible on the web admin serial page, as shown below:

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

$ apt-get install bb-core

Node-RED

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.

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

Two new nodes have been installed onto the palette:

1. FRED nodes: node-red-contrib-fred v0.0.6

1. IBM Watson IoT nodes: node-red-contrib-ibm-watson-iot v0.2.8
