SMS rule execution syntax

---

To execute an SMS rule, send an SMS message to your device's SIM card number with the rule's SMS Text preceded by the selected authorization keyword, which depends on the selected authorization method:

• No authorization - no special keyword required; simply send a rule's SMS Text. For example, to execute the reboot rule without authorization:

  reboot

• By serial - include the device's serial number before a rule's SMS Text. For example, to execute the iostatus rule with serial authorization:

  1111111111 iostatus

  (replace 1111111111 with your device's serial number)
• By device admin password - include the device's password before a rule's SMS Text. For example, to execute the vpnon rule with admin password authorization:

  admin01 vpnon

  (replace admin01 with your device's admin password)
• By password - include the configured custom password before a rule's SMS Text. For example, to execute the sshon rule with password authorization:

  Custompw1 sshon

  (replace Custompw1 with your configured custom password)

Modify SMS Rule

---

Every SMS rule can be edited to your liking. To begin configuring a rule, click the click the 'Edit' button under "Actions" column:

After this you should redirected to configuration page for that rule. Below are examples of what the configuration page for the reboot rule looks like.

General settings

---

1. The Enable slider turn the rule on or off. In order to use a rule, this slider must be set to 'on'. By default, all existing SMS rules are turned on.
2. The Action dropdown selection specifies which action should be performed when the rule is executed.
3. The SMS text field specifies the text that will trigger the rule upon receiving a message.
4. The Get status via SMS after reboot slider specifies whether the device should send a status report message after an action is executed. The name of this slider may differ from rule to rule and it is only available for some rules.
5. The Message forwarding slider specifies whether the device should send a status report message to another number (besides the original sender). Setting this slider to 'on' will prompt you to enter an additional phone number(s) of the status message recipient(s).
6. The Message text box is used to modify the text that should be included in an SMS rule's response message.

Authorization

---

1. The Authorization method dropdown selection specifies the type of authorization an SMS rule requires (device admin password, serial number, password or none). If By password is selected a Password field will appear and a custom password will be required. A custom password must have at least one uppercase letter, one lowercase letter, one number and must be from a minimum of 8 to a maximum of 80 characters in length.
2. The Allowed number(s) dropdown selection specifies who can execute an SMS rule (based on phone number).

---

Most rules are configured in a similar manner. However, the configuration does differ from rule to rule, depending on a rule's purpose (selected 'Action'). If you run into trouble when configuring a rule, hover your mouse cursor over the name of a field to see a hint that explains what that field does.

Change mobile settings (cellular) rule

---

The Change mobile settings rule is used to change the configuration settings of the mobile data connection. The usage of this rule is a bit more complex because the SMS text in and of itself does nothing, as you must also specify the parameters and values that you wish to set. For example, you can send a message that will change your APN only or a message that will change multiple parameters at once.

Below is the full list of parameters that can be changed with this rule.

Parameter	Description	SMS text example
apn=	Sets APN.	cellular apn=internet
auto_apn=	Turns auto APN on or off. Possible values are 0/1.	cellular auto_apn=1
dialnumber=	Sets Dialing number.	cellular dialnumber=*99***1#
auth_mode=	Sets the authentication method. Possible values are: none pap chap	cellular auth_method=pap
service=	Sets the service mode. Possible values are: 2g 3g lte mixture of any two modes (ex.: 3g_lte) auto	cellular service=auto
username=	Sets the user name for PAP or CHAP authentication.	cellular username=user
password=	Sets the password for PAP or CHAP authentication.	cellular password=pass
roaming=	Turns mobile data roaming on or off. Possible values are: 0 - for off. 1 - for on.	cellular roaming=0
interface=	Specifies the interface where changes should occur.	cellular apn=internet,interface=mob1s1a1

Each example above contains a single parameter but you can also send out multiple parameters in one message. For example:

cellular apn=internet service=3g

This message would set your APN to "internet" and the service mode of the mobile connection to "3G Only". You can also send a message that would include all of the parameters above:

cellular apn=internet auth_mode=pap service=3g username=user password=pass roaming=0

Note: only "apn=" or "auto_apn=" is required in a message. For example, to set custom APN:

cellular apn=internet

or if you want to turn auto APN on:

cellular auto_apn=1

UCI API rule

---

The UCI API rule is used to configure any parameters on the device.

---

The following are syntax examples for the UCI API rule:

Structure example	Description	SMS text example
uci get <config>.<section>.<option_name>	Returns the value of a single configuration option.	uci get network.wan.ipaddr Returns the router's WAN IP address.
uci set <config>.<section>.<option_name>="value"	Sets the value of a specified configuration option.	uci set network.mobile.apn=example Changes mobile APN value to "example".
uci show <config>	Returns the contents of a config file	uci show openvpn Returns the contents of the "openvpn" config file.
uci show <config>.<section>	Returns the exact part (section) of a config file.	uci show network.lan Returns the configuration of the "lan" section from the "network" config file.

The UCI rule requires that you know the names of the configuration files and sections and parameters contained within them. You can find the config file list and some examples of the UCI system usage in our UCI command usage article.

Disclaimer: do not enclose values in escape characters like you would when executing UCI commands via CLI. For example: uci set network.mobile.apn="example" will cause an error in SMS API and your value will be altered, as a result, UCI commands execution will fail. Instead, simply write uci set network.mobile.apn=example without any escape characters or quotes.

API rule

---

API allows creating, reading, updating, or deleting configurations using the allowed API endpoints from a list.

---

The following are syntax examples for the API rule:

Structure example	Description	SMS text example
api get <method>.<config>.<section>	Returns specified config options.	api get /auto_reboot/periodic/config Returns periodic reboot options.
api post<method> <config>.<section>.<option_name>="value"	Sets the value of a specified configuration option.	api post /auto_reboot/periodic/config {"data": {"action": "1", "period": "week", "days": ["mon"], "time": ["12:00"]}} Creates a periodic reboot configuration with options to reboot device every monday on 12:00.
api put <method> <config>.<section>.<option_name>="value"	Edits a specified config options.	api put /auto_reboot/periodic/config/{id} {"data": { "enable": "1"}} Sets a specified periodic reboot config to enabled.
api delete <method> <config>.<section>.<config_id>	Deletes a specified configuration.	api delete /auto_reboot/periodic/config/{id} Deletes a specified periodic reboot configuration.

Custom Rules

---

If none of the default rules suit your purposes, you can also configure custom ones. To do so, scroll down to the very bottom of the SMS Utilities page, where you will find the Add Rule section. Enter a custom SMS text, select an Action and click the 'Add' button:

SMS Gateway

This section provides a summary of the SMS Gateway functions for TRB140 devices.

Email To SMS Forwarding

---

Email to SMS Forwarding is a function that connects to your email account and checks its inbox at the specified frequency. If it finds any new received emails with a specific subject (phone number in email subject), it sends the body of the email as an SMS message(s) to the recipient specified in the email subject field.

Important note: all POP3 server email messages from inbox will be deleted when using this service.

Field	Value	Description
Enable	off | on; default: off	Turns Email to SMS Forwarding ON or OFF
POP3 server	host | ip; default: none	Email service provider's POP3 server address (can be looked up online)
Server port	integer [0..65535]; default: none	Email service provider's POP3 server port (can be looked up online)
User name	string; default: none	Email account user name. This is information is used by router in order to atuhenticate itself when connecting to the email client

Secure connection (TLS)	off | on; default: off	Enables/diables secure connection (TLS 1.2 and up). TLS (Transport Layer Security) is a cryptographic protocol designed to provide communications security over a computer network. TLS uses a combination of symmetric cryptography (sigle secret key known to both sender and receiver to encrypt data) and asymmetric cryptography (a public key known to everyone and a private or secret key known only to the recipient of the message) to encrypt data.
Verify TLS certificate validity	off | on; default: off	Enables/disables TLS certificate validation. When enabled verifies the validity of the POP3 server certificate
SMS PDU limit	integer; default: 5	Longer email text will be sent in multiple PDUs (Protocol Data Units), each of them is approximately 130 characters. Specify maximum allowed PDU count
Check email every	time; default: 1 minute	Email inbox check interval
Interval	Minutes | Hours| Days; default: Minutes	Email inbox check interval

Additional note: you may have noticed that there is no option where you can specify the recipient's phone number. As mentioned earlier, Email to SMS doesn't forward all emails, only the ones that are meant to be forwarded. Only emails with the recipient's phone number in the subject will be forwarded to SMS

Correct phone number format is:

• 00 - number must be preceded by two zeros
• <country_code> - the next following element is the number holder's country code
• <receivers_number> - phone number of the recipient

For example, a valid number would be 0037012345678 (370 is country code and 12345678 is the receiver's phone number, all preceded by 00)

Recommendations note:

• Email to SMS application can't guarantee best results when working with flooded email inbox. It is recommended to have less than 100 emails in the inbox.
• Less emails - better performance.
• In most cases it is best to use dedicated inbox.

SMPP

---

Short Message Peer-to-Peer (SMPP) is a protocol used for exchanging SMS messages between Short Message Service Centers (SMSC) and/or External Short Messaging Entities (ESME). It supports both IPv4 and IPv6 addresses. The figure below is an example of the SMPP section and the table below provides information on the configuration fields contained in that section:

Field	Value	Description
Enable	off | on; default: off	Turns SMPP on or off.
User name	string; default: admin	User name used for authentication on the SMPP server.
Password	string; default: admin01	Password used for authentication on the SMPP server.
Server port	integer [0..65535]; default: 2775	SMPP server port.

CA file	-interactive button; default:	Upload CA file.
Certificate file	-interactive button; default:	Upload certificate file.
Key file	-interactive button; default:	Upload key file.

Call Utilities

Just like SMS Utilities, Call Utilities provide you with the possibility to issue certain commands to the router from your mobile phone. The list of possible rules is of course shorter because you can only make one type of call. Keep that in mind when creating Call Utilities rules because one call will trigger all of the enabled rules at once.

Messages

With the help of the Messages window you can read and send SMS messages.

Read Messages

---

In the Read Messages section you can read and delete received/stored SMS messages. The layout is simple, there is a list of received SMS messages and you can choose how many entries of that list should be visible at one time with SMS per page drop box in the top left corner of the page and there is a Search field to help you navigate more efficiently through the list of messages in the top right corner of the page.
