===== Configure CLI =====

==== First step need get IP addres and telnet acces key ====
  - After first upload firmware via USB, open serial monitor in Arduino IDE (Ctrl+Shift+M) and set
    - baudrate to 115200
    - No Line ending
  - write <code>?</code> and press enter show settings Command line interface \\ {{https://remoteqth.com/img/3d-wx-station-07.png?300}} \\
  - Now **copy and save**
    * **IP** address
    * **Key** for telnet access (100 characters)
Key are generated automatically from internal pseudo random generator after start if EEPROM is clear. Therefore you can generate new key after clear EEPROM with **E** command.

==== Second step connect remotely via IP ====

  * Download and install [[https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html|PuTTY]]
  * In menu Terminal preset CR/LF and line discipline by picture \\ {{https://remoteqth.com/img/wiki-ip-switch-esp32gateway-22.png?200}} \\
  * In main menu Session select or set the following values \\ {{https://remoteqth.com/img/wiki-ip-switch-esp32gateway-23.png?200}} \\
    * select **Telnet**
    * port **23**
    * write **IP address** (saved from first step acces)
    * Sessions may be saved for next time
    * for connect press **Open**
  * Login confirm with press <code>y</code>
  * Now answer four times the question of what character is on random selected position, **in your key** (key saved from first step acces). Key formated in groups of ten - FOR EXAMPLE<code>Position  KEY
 1-10     pP75tf8qrF
11-20     y4SK57dpnC
21-30     fpag8x9eZ4
31-40     IsueSv4jCY
41-50     pX3lpK4UPD
51-60     ij1bbLEQRu
61-70     XRr9dfoJje
71-80     44u5MYQdcm
81-90     B68NpG7F0t
91-100    5mD04pAE6s</code>
  * if you **enter wrong three times,** login will be **blocked for next ten minutes**
  * After login your IP address store to EEPROM and next key will be required **only if change your IP** address 
  * Now logged in to CLI (command line interface) via telnet \\ {{https://remoteqth.com/img/3d-wx-station-08.png?400}}
  * for **Logout** press **q** \\

==== How command are available ====
| **?** | List status information and command |
| **a** | set wind speed alert, if exceed limit (not implemented) |
| **O** | set pressure ofset in hPa |
| ***** | enable/disable serial/telnet debug, switching between three status \\ disable, enable, enable frenetic mode |
| **+** | change MQTT broker IP and port - defailt value used RemoteQTH.com public MQTT broker |
| **L** | change location name, or callsign with ssid if enable APRS |
| **A** | enable/disable upload to hamradio APRS network (requires a valid license) |
| **s** | enable/disable external temperature sensor DS18B20 \\ connected to P4 by this schematics/picture \\ {{https://remoteqth.com/img/wiki-wx-station-01.png?x300}} \\ **NOTICE** \\ If use external temperature sensor DS18B20, \\ **must add 4k7 pull-up rezistor** \\ between +3,3V and data (pin 1 and pin3 on P4 connector) \\ {{https://remoteqth.com/img/wiki-wx-station-02.jpg?x500}} \\ \\ How to build [[3d_print_wx_station#passive_thermometer_sun_shield|passive thermometer sun shield]] |
| **q** | disconect telnet, also show login verified IP address |
| **Q** | disconect telnet with erase verified IP addres - will be required key in the next time you log in |
| **e** | list EEPROM (only for debbuging) |
| **.** | reset half hour timer and send measure to MQTT (and APRS if enable) |
| **@** | restart device (causes telnet disconnection) |

==== Third step - MQTT ====

If open IP address of WX station in web browser, load MQTT-wall. \\
That propagate every half hour last measured value. \\ {{https://remoteqth.com/img/3d-wx-station-09.png?400}}
