Tunnel – Reading of analog and digital inputs and switching of relays from an Android app via Bluetooth and GPRS/3G

< Back to Knowledge Base

Scenario details:

  • An app for Android telephones that allows for the automatic control of a loft is designed. We need to know the status of three windows (open/closed) as well as the status of the entrance door (open/closed). In a similar way, we wish to monitor the temperature at any time. Via 4 relays, we want to be able to: 1.- activate/deactivate the heating; 2.- activate/deactivate the main light; 3.- open/close the mechanical shutters
  • The app must show the information previously mentioned. It must also have buttons to be able to switch the different relays
  • The reading of analog and digital inputs, temperature and the switching of relays must be available via Bluetooth and GPRS/3G
  • In order to read temperature, an MTX-Temp-RS485 (modbus) sounding line will be connected to the terminal

Solution: MTX-3G-Java-BAT (with Bluetooth) modem + MTX-Tunnel software

EXAMPLE of settings (file config.txt) for such scenario:

Details:

  • The application is only available for Android and Windows telephones, and those devices that support Bluetooth communications using SPP protocol (Apple products do not support this for example)
  • As can be seen by analyzing the configuration file, the app must be programmed for communications with MTX-IND-3G-Java and to carry out readings of the digital inputs, switching of relays and measuring the temperature via AT commands send from a mobile phone to the MTX terminal.
  • In this manual, you will find the necessary AT commands for this. To read the digital inputs, we have the “AT^MTXTUNNEL=GETIOS” command. To switch relays, we have the “AT^MTXTUNNEL=SETRELAYS” command. To read modbus devices, we have the “AT^MTXTUNNEL=GETMODBUS” command.
  • The AT commands can be sent via 3G or via Bluetooth. To be able to send AT commands via 3G, first we must establish a Telnet connection on the MTX device. To be able to sent AT commands via Bluetooth, first we need to create an SPP (Serial Port Profile) Bluetooth connection from the mobile phone to MTX

FAQ

No, the concentrator is not able to decrypt data from WM-BUS equipment because it does not have a safe on board to guarantee the security of the encryption keys of your equipment. The recovered data is deposited without modification (without decryption) by the concentrator on your remote server.
Please check these items in this order:
  • the battery level: if the battery level is too low or empty, the product will not run properly or not run at all.
  • Modem reception level: a bad signal at the modem may also prevent the hub from uploading files. Look to move the product or install an external antenna to improve signal quality.
  • The last configuration file: a bad configuration file can block the product.

Remotely, by checking the regularly uploaded files if the product configuration is correct.

On site, by passing the magnet over the product, you will hear 3 short beeps.

Replace the product and inject the configuration from the old product into the new one. If a white list is used, remember to inject it into the new product as well.

There are two configuration solutions, using the web interface and using text messages:
  • Configuration using the web interface:
Start by establishing a connection to the concentrator by connecting to it to access the server configuration: Enter the “ethernet” or “modem” connection type: For an ethernet configuration, make sure the IP parameters are compatible with server access according to the concentrator local network configuration. For an ethernet connection, the configuration must be compatible with the concentrator’s local network topology so that it can access the servers. This configuration is done from the “Networks” configuration page (see section 3.2.2.3: “Networks”). For a modem connection, the modem configuration must be correct before a connection can be set up. This configuration is done from the “Modem” configuration page (see section 3.2.2.4: “Modem”). The parameters for the servers to be configured are at least the following: Therefore the following fields need to be configured: “Interface”, “Type”, “Server type”, “Address”, “Port”, “Login” and “Password”. The other fields can be left at the default values subject to the directories having been properly created beforehand. See section 3.1.2: “Configuration files” for more details.
  • Text message configuration:
Text message configuration requires sending the following commands:
      • Apn: to configure the SIM card APN. (see section 3.2: ““apn” modem configuration command)
      • Ftp: to configure the FTP server that will contain the concentration configuration (see section 3.3: ““ftp” FTP configuration command”).
      • Connect: to launch the connection to the FTP server and load the configuration (see section 3.1: ““connect” connection command

Access to the FTP server depends on the selected solution.

If you have chosen a portal, it will give you the FTP server access identifiers.

If you want to use your own FTP server, contact your network administrator.

For all other configurations, and to determine the best solution, contact the Webdyn sales department which will advise you and direct you to the relevant contacts: contact@webdyn.com

General gateway use

There are 2 methods to force a concentrator factory reset:
  • Press the Factory Reset button on the concentrator for 20 seconds:
Wait. The concentrator will reboot using its factory configuration.
  • If a SIM card is installed and configured, a “factory” text message can also be used for factory reset. Just send the “factory” text message to the SIM card phone number (see section 3.7: ““factory” reset command”)

It is possible to send commands to connected devices if they accept them.

The WebdynSunPM can store up to 50Mb of uncompressed data per declared device.

If there is no access to the remote server, the WebdynSunPM concentrator can store the data for several months.

The maximum data storage time varies depending on the amount of data to be collected and the configured collection frequency.

The average storage time varies from 3 to 4 months.

The average service life of the battery is 5 years.

It may vary depending on the installation environment.

All our products are guaranteed for 2 years.

CONFIGURATION OF THE WEBDYNRF GATEWAY

  • If the file is deleted from the directory after connecting the WebdynRF gateway, the problem is usually due to a file format error. The configuration and control files must follow the format described in the schema (XSD) files. To check schema consistency, open the XML file with the Notepad++ text editor and install the “XML Tool” add-on. Next, copy the corresponding XSD file to the XML file in the same directory, and select “Validate now” in XML Tool. Errors detected by the tool should be displayed.
  • If the file is not deleted from the server, the most common problem is that the file has not been located correctly. The file must be available on the server in the “INBOX” directory and in the sub-directory bearing the product UID name (e.g.: “/INBOX/0045CE/”).

GENERAL USE OF THE WEBDYNRF GATEWAY

The amount of data exchanged on the GPRS network varies depending on the configuration. However, the average consumption would be about 5MB / month.
The WebdynRF gateway consumes an average of about 250mA.

There are 2 firmware updating methods:
Local updating:
On the WebdynRF configuration interface, go to the “Actions” tab and select the updater in the “File upload” menu before clicking on the “Upload” button

Remote updating:
Upload the file containing the updater (file with extension “.bz2”) in the “BIN” directory to the FTP server . Next, place the update command in the INBOX directory corresponding to your gateway (“INBOX/”, with, the identifier of the gateway concerned)

The update command must follow the following format:

      updater.tar.bz2
      checksum_md5

updater.tar.bz2
checksum_md5

With:

  • updater.tar.bz2: Updater file name uploaded to the “BIN” directory
  • checksum_md5: Md5 code of the updater file

A lack of connection to the FTP server may be due to a network connection problem (Ethernet or GPRS), an FTP login problem or a failure to initiate the connection.

If you cannot connect to the network, check the following points:

  • Ethernet:
    • Modem set to “off” or “always off”
    • “Gateway” fields correctly entered
    • At least one DNS server must be configured
  • GPRS:
    • Modem set to “on”
    • APN, APN ID and APN password correctly entered
    • GPRS call number set to “*99***1#”

If you cannot log in, check the following points:

  • Incorrect FTP parameters
  • TCP port 21 closed at output
  • Domain name resolution problem: the DNS server is not specified

If the connection fails to initiate:

In this case, only the automatic connection does not work. The problem is probably caused by an incorrect schedule configuration. Please note, the schedule ID must be an integer.

 PARTICULAR APPLICATION OF THE WEBDYNRF WIRELESS M-BUS GATEWAY

For the WM-bus module data to be transmitted, you must:

  • Choose the mode corresponding to the modules used (S, T or N)
  • Define the modules or groups of modules to be processed

A module may be defined in a unique way by all the fields below:

  • Id
  • Manufacturer
  • Version
  • Medium

If a module’s data is encrypted, the encryption key for this module can be defined in the “Key” field.

To simplify the entry of the modules to be processed, a module group can be defined that conforms to the fields entered. The other fields will then be left empty (below is an example of a configuration for retrieving all Webdyn manufacturer (WDN) modules with the encryption key “00000000000000000000000000000000”.

  •   Id :
  •   Manufacturer : WDN
