for the LCD20x4 how to control the 4 buttons using the MQTT Proxy, e.g. when pressing a Button an action is triggered using publish and how to subscribe.


the Brick MQTT Proxy is a great extension - simplified a lot.

Looking at the example below, how to display f.e. the special char ° which is HHHHHHHL according the special char table.

Example Publish Command:

General Discussion / Red Brick not booting
« on: January 03, 2015, 16:53:05 »

after connecting my (new) red brick via USB to a windows PC and configuring using the Brick Viewer. I rebooted the brick BUT ...the Green Light is ON (Linux bootmodus) but not blinking (Linux ready). Can also not connect via the Brick Viewer. The Brick has a wlan adapter and is reachable using ping.

Any hints?

Hi All,

want to share example apps to control the Master Brick and Bricklets using B4x (see - Rapid Application Development (RAD) tools for native Android (B4A), iOS (B4i) and desktop / webserver apps (B4J)). So far, have not seen any TinkerForge examples using B4x. With B4x it is rather simple to control Bricks using the Java Library. It is also possible to use the JavaScript Library.

Additional information & examples
Control Bricklets RemoteSwitch, Temperature, Humidity
B4A & B4J App using TinkerForge Java API Binding.

Raspberry Pi Webserver to control Bricklet RemoteSwitch
B4J Webserver using JQuery Mobile & TinkerForge JavaScript API Binding.

More apps under Development.


what is the best way, in JavaScript, to fast (=immediate) check if a) the HOST is reachable and b) the bricklet is connencted.
There should no delay in response after trying to connect.
If an error, then the result to be messaged to the user.


Hi All,

have build an app (based on the JavaScript API) using the remote switch bricklet to switch devices ON/OFF.
When starting the App, would like to determine the state of a remote switch to be able to set the initial state of the switches in the app.

Question: Is there a (JavaScript) function available? like getRemoteSwitchState resulting in on or off?



versuche beispiel ExampleAuthenticate.pas auszuführen, aber erhalte timeout fehler bei sender.Authenticate.

Habe die gleichen angaben für HOST, PORT und SECRET verwendet, wie für den Brick Viewer (funktioniert einwandfrei). Auch mittels funktioniert es.

Zugriff erfolgt via internet auf ein raspi server.

Was könnte das problem sein?

« on: May 28, 2014, 14:38:22 »

bin neueinstiger. das remote starter kit installiert und remote schalter können via brick viewer geschaltet werden, aber via IOT-REMOTE.COM nicht?
Brick Viewer Setup: Host: localhost, Port=4223; Keine Auth.

Wer hat einen tipp?
