+##### This is the development version that supports the sending of SMS. This is a work in progress and is not meant to be used in production at this time. This will become the 2nd genreation of the project.
+
+# HBLink3 with APRS/SMS Features
+
+This is a **fork** of the [HBLink project](https://hblink-org.github.io/) that supports APRS and DMR SMS functions.
+
+This repository contains everything needed to setup an HBLink server with APRS/SMS features.
+
+The development server can be found at [https://hbl.ink](https://hbl.ink).
+
+## Features
+
+* Decode GPS locations and upload APRS position packets
+* Each user/DMR ID can customize APRS options (SSID, icon, comment)
+* Send and receive APRS messages as DMR SMS
+* Ability to receive data as a private call or group call
+* Trigger a command or script via DMR SMS
+* Optional web dashboard to show APRS packets uploaded
+* See location of radios on dashboard map
+* Use built in API to send SMS to other HBLink servers
+* Ability to disable APRS and just use dashboard map
+* Use [external applications](https://github.com/kf7eel/hblink_sms_external_apps) (see [API Documentation](https://kf7eel.github.io/hblink3/api_doc.html)) for weather reports, email, and other information.
+
+#### Required modules
+
+* pynmea2
+* aprslib
+* maidenhead
+* libscrc
+
+#### Optional Modules
+* Flask - Required for dashboard
+* folium - Required for mapping on dashboard.

+
+## Would like to test:
+
+Connect Systems GPS enabled radios
+
+## How it works
+
+A user should configure their radio for the DMR ID of the application and private or group call. When a position is received by the application, it will extract the coordinates and create an APRS position packet. The application will find the callsign of the user based on the sending radio's DMR ID. It is essential to have an up to date subscriber_ids file for this to work. A predefined APRS SSID is appended to the callsign. The APRS location packet is then uploaded to APRS-IS. No setup is required beforehand on the part of the user. This is pretty much "plug and play."
+
+For example, N0CALL has a DMR ID of 1234567. N0CALL's radio sends a position to the application. The application will query the subscriber_ids file for DMR ID 1234567. The result will be N0CALL. An APRS location pack is created and uploaded to APRS-IS.
+
+## Individual user/DMR ID APRS settings
+
+By default, all APRS positions will have an SSID of 15, a default comment, and the callsign of the DMR user. These default settings can be changed. 
+
+The comment, SSID, and icon can be set for each individual user/DMR ID the application sees. The application stores all the setting in a file. You may have different SSIDs, icons, and comments for different DMR IDs. This is done via DMR SMS using the following commands:
+
+ | Command | Description | Example |
+ |-------|:---:|:---:|
+|**SSID**|Change SSID of user callsign.|`SSID 7`|
+|**ICON**|Change the icon of the APRS position. *See [http://aprs.net/vm/DOS/SYMBOLS.HTM](http://aprs.net/vm/DOS/SYMBOLS.HTM) for icon list.|`icon /p`|
+|**COM**|Change the comment of the APRS.|`COM This is a test comment.`|
+|**MH**|Set you location by maidenhead grid square. Designed for radios with no GPS or that are not compatable yet.|`MH DN97uk`| 
+|**BB**|Post a bulliten to the web dashboard.|`BB This is a test bulletin.`|
+|**@[CALLSIGN W/ SSID] [MESSAGE]**|Send a message to another station via APRS.|`@N0CALL-15 This is a test.`|
+|**[EMAIL ADDRESS] [MESSAGE]**|Send an email to an email address.|`test@example.org This is a test.`| 
+|**REM MAIL**|Remove all mail (APRS messages, SMS, etc) addressed to you.|`REM MAIL`|
+**@NOTICE**|Used to prominantly display a notice, similar to EMERGENCY activation.|`@NOTICE Server going down at 1800`|
+|**@SOS**|EMERGENCY activation displays a banner on the main dashboard page.|`THIS IS AN EMERGENCY. @SOS`|
+|**REM SOS**|Removes an EMERGENCY or notice.|`REM SOS`|
+|**ID**|Responds by send an SMS containing your DMR ID.|`ID`|
+|**TEST**| Responds with "This is a test." as an SMS.|`TEST`|
+|**?[Network Shortcut] [DMR ID] [Message]**| Send an SMS to a user on another network.|`?XYZ 123456789 This is a test`|
+|**?[App Shortcut] [Input]**|Send SMS to an external application.|`?BBD This is a test post.`|
+|**APRS ON**|Enable sending and receiving of APRS messages.|`@APRS ON`|
+|**APRS OFF**|Disable sending and receiving of APRS messages.|`@APRS OFF`|
+
+
+
+Send a DMR SMS to the configured dmr_data_id in the application with the desired command followed by the value. For example, to change your icon to a dog, the command would be `@ICON /p` (see the icon table for values). Changing your SSID is as simple as `@SSID 7`, and `@COM Testing 123` will change the comment. 
+
+Sending `@BB Test` will result in a post to the bulletin board with the message of "Test".
+
+
+**To remove any of the stored values, just send the appropriate command without any input.** `@COM` will remove the stored comment, `@ICON` will remove the stored icon, and `@COM` will remove the stored comment. Any position now reports sent will have the default settings.
+
+## API
+The API built in to the dashboard can be used to exchange SMS with other HBLink servers/networks or be used to access external applications that provide functionality via SMS. Multiple servers/networks can share a single external application.
+
+See [hbl.ink](https://hbl.ink) for publicly accessible external applications that you can use.
+
+See [API documentation](https://kf7eel.github.io/hblink3/).
+
+Repository for [external applications](https://github.com/kf7eel/hblink_sms_external_apps), if you want to host your own.
+
+
+## Web Dashboard
+
+The web dashboard is completely optional. Python module flask is required for this to work. The web dashboard will display the last 15 positions of radios sent to APRS-IS. The dashboard will also sh user bulletin. A bulletin is a message sent via SMS that will display on the web dashboard. There are several uses for this, including: testing SMS functionality of radio, announcements, and moire. It is a novel feature. The page will automatically reload every 2 minutes. Setup is rather simple. Just modify the example config in the dashboard directory and rename it to dashboard_settings.py. Then start dashboard.py. 
+
+## APRS messaging
+
+You can send and receive APRS messages via DMR SMS. APRS messages received by the gateway are automatically sent to your DMR ID as a private SMS.
+
+## APRS TOCALL
+
+The project was granted a [tocall](http://www.aprs.org/aprs11/tocalls.txt) of **APHBLx** by Bob Bruniga, WB4APR. This will identify that your APRS position came from HBLink. The x on the end can be any letter/number. Here are the current designations of APHBLx:
+
+* **APHBL3** - HBlink3 D-APRS gateway
+* **APHBLD** - DMRlink D-APRS gateway (the IPSC version of the project)
+
+
+## Configuration
+
+See hblink_SAMPLE.cfg, rules_SAMPLE.py, and gps_data_SAMPLE.cfg for examples.
+
+## Special thanks to:
+
+**N0MJS** - For creating HBLink and dmr_utils. This project not possible without him.

+# OPENBRIDGE INSTANCES - DUPLICATE SECTION FOR MULTIPLE CONNECTIONS
+# OpenBridge is a protocol originall created by DMR+ for connection between an

+# of the Brandmeister team as a way to legitimately connect HBlink to the
+# Brandemiester network.
+# It is recommended to name the system the ID of the Brandmeister server that
+# it connects to, but is not necessary. TARGET_IP and TARGET_PORT are of the
+# Brandmeister or IPSC2 server you are connecting to. PASSPHRASE is the password
+# that must be agreed upon between you and the operator of the server you are
+# connecting to. NETWORK_ID is a number in the format of a DMR Radio ID that
+# will be sent to the other server to identify this connection.
+# other parameters follow the other system types.
+#
+# ACLs:
+# OpenBridge does not 'register', so registration ACL is meaningless.

+THIS EXAMPLE WILL NOT WORK AS IT IS - YOU MUST SPECIFY YOUR OWN VALUES!!!
+
+This file is organized around the "Conference Bridges" that you wish to use. If you're a c-Bridge
+person, think of these as "bridge groups". You might also liken them to a "reflector". If a particular
+system is "ACTIVE" on a particular conference bridge, any traffid from that system will be sent
+to any other system that is active on the bridge as well. This is not an "end to end" method, because
+each system must independently be activated on the bridge.
+
+The first level (e.g. "WORLDWIDE" or "STATEWIDE" in the examples) is the name of the conference
+bridge. This is any arbitrary ASCII text string you want to use. Under each conference bridge
+definition are the following items -- one line for each HBSystem as defined in the main HBlink
+configuration file.
+
+    * SYSTEM - The name of the sytem as listed in the main hblink configuration file (e.g. hblink.cfg)
+        This MUST be the exact same name as in the main config file!!!
+    * TS - Timeslot used for matching traffic to this confernce bridge
+        XLX connections should *ALWAYS* use TS 2 only.
+    * TGID - Talkgroup ID used for matching traffic to this conference bridge
+        XLX connections should *ALWAYS* use TG 9 only.
+    * ON and OFF are LISTS of Talkgroup IDs used to trigger this system off and on. Even if you
+        only want one (as shown in the ON example), it has to be in list format. None can be
+        handled with an empty list, such as " 'ON': [] ".
+    * TO_TYPE is timeout type. If you want to use timers, ON means when it's turned on, it will
+        turn off afer the timout period and OFF means it will turn back on after the timout
+        period. If you don't want to use timers, set it to anything else, but 'NONE' might be
+        a good value for documentation!
+    * TIMOUT is a value in minutes for the timout timer. No, I won't make it 'seconds', so don't
+        ask. Timers are performance "expense".
+    * RESET is a list of Talkgroup IDs that, in addition to the ON and OFF lists will cause a running
+        timer to be reset. This is useful   if you are using different TGIDs for voice traffic than
+        triggering. If you are not, there is NO NEED to use this feature.

+<h2 style="text-align: center;">Attention:</h2>
+<p><span style="color: #ff0000;"><strong>Please be aware that many (if not all) DMR radios DO NOT transmit your callsign when sending a GPS position. It is your responsibility to identify your station per the regulations of your country.</strong></span></p>
+<p>&nbsp;</p>
+<p>{{description}}</p>
+<p>Configure your radio to send GPS positions with the following settings:</p>
+<table style="margin-left: auto; margin-right: auto;" border="black">
+<tbody>
+<tr>
+<td style="text-align: center;"><strong>Data Call Type</strong></td>
+<td style="text-align: center;"><strong>DMR ID</strong></td>
+</tr>
+<tr>
+<td style="text-align: center;">&nbsp;{{data_call_type}}</td>
+<td style="text-align: center;">&nbsp;{{data_call_id}}</td>
+</tr>
+</tbody>
+</table>
+<p>&nbsp;</p>
+<p>When a position is received by this gateway, it will extract the coordinates and create an APRS position packet. This gateway will find your callsign based your radio's DMR ID. It is essential to have your information up to date with <a href="https://radioid.net/">RadioID.net</a>. A predefined APRS SSID of <strong>{{aprs_ssid}}</strong> is appended your callsign. The APRS location packet is then uploaded to APRS-IS. No setup or account creation is required beforehand. This is pretty much "plug and play."</p>
+<p>For example, N0CALL has a DMR ID of 1234567. N0CALL's radio sends a position to this gateway with the call type settings above. This gateway will query the <a href="https://radioid.net/">RadioID.net</a> database for DMR ID 1234567. The result will be an APRS location packet with APRS SSID&nbsp;{{aprs_ssid}}. </p>
+<p>You can change the default APRS settings for your radio via SMS.</p>

+<p><strong>Commands should be in upper case.</strong> Send an SMS to <strong>{{data_call_id}}</strong> as a <strong>{{data_call_type}}</strong> with the desired command followed by the value. For example, to change your icon to a dog, the command would be <code>@ICON /p</code> (see the icon table for values). Changing your SSID is as simple as <code>@SSID 7</code>, and <code>@COM Testing 123</code> will change the comment.</p>
+<p>Sending <code>@BB Test</code> will result in a post to the bulletin board with the messaage of "Test".</p>
+<p><strong>To remove any of the stored values, just send the appropriate command without any input.</strong> <code>@COM</code> will remove the stored comment, <code>@ICON</code> will remove the stored icon, and <code>@ICON</code> will remove the strored icon. Any position reports sent will have the default settings.</p>
+
+<h3 style="text-align: center;">EMERGENCY Activation</h3>
+<p>The EMERGENCY Activation function will display a prominant banner accross the main dashboard page. The banner contains a message, time, callsign of station, and a link to the last known location of the station. This feature is intended to be used in situations where a user is in distress. To trigger an EMERGENCY activation, simply send an SMS to <strong>{{data_call_id}}</strong> with <strong>@SOS</strong> in the message. The <strong>@SOS</strong> command can be anywhere in the message. A less intimidating banner can be displayed for testing, or other purposes, by using <strong>@NOTICE</strong>. To remove the EMERGENCY activation, simply send the <strong>@REM SOS</strong> command.</p>
+<h3 style="text-align: center;">The Map</h3>
+<p>This dashboard now has a built in map. The map will display the last know location of stations and some previous plots from them. You can track a station by clicking on the red pin, and selecting the <strong>Track Station</strong> link. When tracking a station, you have a few options for a refresh rate, located in a drop down menu.</p>
+<h3 style="text-align: center;">The Mailbox</h3>
+<p>The Mailbox is a place where users can leave messages via DMR SMS. A user can leave a message for someone else by sending a formatted SMS to <strong>{{data_call_id}}</strong>. See the table above for a syntax example of posting a message to the Mailbox. The message recipient can then use the mailbox to check for messages. Message recipients can delete all of their messages by sending the command <strong>@REM MAIL</strong>. There is no way to remove a single message, it's all or none.</p>
