GSM menu

Before the individual functions are defined, the GSM module must be parameterised via the „GSM“ browser menu.Before the SIM card is inserted, PIN querying must be deactivated. This can take place using a mobile phone. Initialisation takes place upon initial setting up of the Bootloader with the GSM module and inserted activated SIM card: the red LED flashes and instead of the network operator being displayed, the following displays are sequentially output “No GSM module available”, „Searching for network“, „INIT“, „DATEN“ (Data) and „INIT“. As soon as the red LED is continuously illuminated, the network operator is displayed and the initialisation is complete.

It is recommended that the contact settings are tested by clicking “ Test contact “.

However, before an email contact can be tested, the WAP - MAIL settings must be made.

„GSM“ menu continued:

Settings for the Bootloader network inputs and outputs, the group queries and WAP/MAIL.

The following Error messages can be displayed in the GSM menu:

All text (Identifiers, Event texts), which can be sent by SMS (text message) or email, must only contain the characters A-Z or 0-9. I.e. they should not contain any special characters (e.g. ä, ü, ö, á, č, +, :, & etc.). Lowercase/uppercase is unimportant. One exception is formed by the special text commands for the heating circuit and the on/off commands for the digital network outputs: These commands must dependent on the BLNET version language (languages other than German from GSM module version 1.4) be written exactly as they are listed in the following table (incl. special characters):

Passwords are case-sensitive.

This sub-menu is for configuring the analog inputs of the Bootloader BL-NET and the contact settings. The values of these inputs can be queried using the SMS query "Identifier?"“ abgefragt werden.

Example: If the event threshold is a temperature, it should be borne in mind that the value is indicated without a decimal point, in the example: „300“ means 30.0°C. The current value can be queried with an SMS text message Tank? The response is an SMS message to the number from which the query was sent, with the texttank = 46.8C! („C“ means „°C“). Also an Event is defined in which should the temperature fall below 30°C, an SMS message or email is automatically sent with the text malfunction/tank = 29.0C to the selected contacts.

This sub-menu is for configuring the digital inputs of the Bootloader BL-NET and the contact settings. The values of these inputs can be queried using the SMS query „Identifier?“.

Example: The current value can be queried with an SMS text message heating pump?. The response is an SMS message to the number from which the query was sent, with the text heating pump = off!. Moreover an Event is defined, where the switching off of the pump automatically sends an SMS message or email with the text message/heating pump=off the selected contacts. The event „H/L“ means a change in state from „ON“ (=High or „1“) to „OFF“ (=Low or „0“), the event „L/H“ a change of state from „OFF“ to „ON“.

If a CAN input is to be changed, the corresponding input number is entered and the desired entry modified and saved. The CAN inputs can be parameterised from the menu „CAN bus“ via the sub-menus „Analog Inputs“ or „Digital Inputs“.

This menu permits the definition of groups, so that not only individual values can be queried, rather entire blocks of values via a group identifier. Up to 8 groups with a maximum of 20 values per group can be defined. The values of these groups can be queried using the SMS query „Identifier?“.

Example: The current group values can be queried with an SMS text message system?. The response is an SMS message to the number from which the query was sent, with the text for all values in the group. If the entire text comprises more than 160 characters, a second SMS message is sent.

Important instructions: Different names must be used to identify the analog and digital inputs and the groups.

SMS-queries always end with a Question mark after the identifier. The use of uppercase or lowercase letters in identifiers is ignored.

In the menu “ Analog outputs “, analog CAN network outputs are configured in the Bootloader, whose value can be set by SMS. An SMS command is specified with a value without decimal points (e.g.: 250 for 25.0°C) (e.g. SMS: „Identifier:250!“). Additionally, the commands standby, time, normal, lowered and internal can be used to change the operating mode of a heating circuit via SMS.

Example: An SMS command Warmwasser:600! sets the value of the analog network output with the identifier, Hot water, to the value 600 (=60.0°C). Likewise an SMS command Warmwasser:60.0! is possible (the value 600 = 60.0°C is forwarded to the CAN-Bus). However, if only Warmwasser:60! is sent, then only a value 60 (= 6.0°C) is transferred to the CAN bus. As confirmation, an SMS is received back, with the text warm water=600 at the number from which the query was sent.

The commands standby, time, normal, lowered and internal can be used to change the operating mode of a heating circuit via SMS. The Bootloader forwards these commands to the CAN network as analog numbers.

The commands standby, time, normal, lowered and internal are forwarded by the Bootloader as analog numbers to the CAN network. Accordingly the corresponding parameterised analog network input must be connected to the input „External switch“ of the heating circuit control function of the UVR1611 (see UVR1611 operating manual, Function Heating circuit controller/External switch).

In the above example the network output analog 2 of the Bootloader is allocated the identifier „heating“. Via an SMS message heating:lowered! the heating circuit changes into lowered mode, while the SMS message heating:internal! causes the internal operating state of the control to become active. As confirmation for the command, an SMS is returned with the text heating=lowered.

Value output for analog commands with text input on the CAN bus:

Within the selected setting „Send duration: 3“ of the example, the Bootloader sends in a minute cycle, after 3 repetitions of the command value, the „Alternative value“ (in the example: 0). This value (0) does not cause any further changes in the heating circuit controller. After the send duration has elapsed, the operating mode can again be manually changed (e.g. on the RAS room sensor, on the CAN monitor, on the controller itself or via a browser).

WARNING! If during the send duration a manual change to the operating mode is made, then the controller does indeed „notice“ this change, however it only acts on it, once the SMS (text) command heating:internal! (or alternative value 127) is issued. If during this time an operating mode other than „RAS“ is selected then, once the send duration elapses, this operating mode cannot be changed on the RAS, rather only on the controller, on the CAN monitor or via the browser.

In the menu “ Digital outputs “, digital CAN network outputs are configured in the Bootloader, whose value can be set by SMS. An SMS command is specified with the value on! or off! (e.g. Identifier:on!).

Beispiel: An SMS command Enable pump:on! sets the value of the digital network output with the identifier “Enable pump” to the value ON. As confirmation, an SMS is received back, with the text Enable pump=on at the number from which the query was sent.

Important instructions: Different names must be used to identify the analog and digital outputs. SMS-Commands always end with an Exclamation mark after the identifier. The use of uppercase or lowercase letters in identifiers is ignored.

The settings for the sending of email and the firmware updating of the GSM module are made in the „WAP – MAIL“ menu.

The save tick must be clicked each time a value is input.

A password should be set to prevent unauthorised access to the module. To activate this password protection at least one contact number must be entered in the „GSM“ menu. If no contact number is entered, then querying can take place from any number even if a password is set. If a password is set and at least one entered contact number, it is possible to create queries or commands from another number, if the password is entered and then terminated with a semicolon (;). Passwords are case sensitive!

Example: Password = ta (= factory setting) SMS query: ta;collector?

Setting and deleting of the password Setting and deleting of the password can only be carried out from one of the listed contact numbers. It is not sufficient if the password is positioned at the start of the SMS message.

Set password command: setpw:password!

Delete password command: pwclear! Resetting the boot loader to factory settings does not delete the password in the GSM module.

The SMS command software? is used to query the version of the GSM module. In response an SMS message is received specifying the software module (e.g. 1.4.0 = version 1.4) and the IMEI number.

The update command can be used to set the GSM module to a new or older software version. This SMS command can only be sent from one of the registered contact numbers. Update command: For example: update to version 1.4: update:4! The necessary identifier can be taken from update instructions of our homepage.
Data transfer costs may arise during an update, dependent on the contract you have with your mobile phone provider! (approx. 70 KB)

A 12V power unit (CAN-NT) must be used to provide a reliable power supply. To ensure automatic sending of an SMS or email message in the event of a power failure, (Activation „power supply “ in the contact data), the fitting of a 9V battery in the boot loader is necessary.
