+# Console command ifconfig
+The component offers a console with a command that enables runtime network interface configuration and monitoring for any example project.
+
+## API
+
+### Steps to enable console in an example code:
+1. Add this component to your project using ```idf.py add-dependency``` command.
+2. In the main file of the example, add the following line:
+    ```c
+    #include "console_ifconfig.h"
+    ```
+3. Ensure esp-netif and NVS flash is initialized and default event loop is created in your app_main():
+    ```c
+    ESP_ERROR_CHECK(esp_netif_init());
+    ESP_ERROR_CHECK(esp_event_loop_create_default());
+    esp_err_t ret = nvs_flash_init();   //Initialize NVS
+    if (ret == ESP_ERR_NVS_NO_FREE_PAGES || ret == ESP_ERR_NVS_NEW_VERSION_FOUND) {
+        ESP_ERROR_CHECK(nvs_flash_erase());
+        ret = nvs_flash_init();
+    }
+    ESP_ERROR_CHECK(ret);
+    ```
+4. In your app_main() function, add the following line as the last line:
+    ```c
+    ESP_ERROR_CHECK(console_cmd_init());     // Initialize console
+
+    // Register all plugin command added to your project
+    ESP_ERROR_CHECK(console_cmd_all_register());
+
+    // To register only ifconfig command skip calling console_cmd_all_register()
+    ESP_ERROR_CHECK(console_cmd_ifconfig_register());
+
+    ESP_ERROR_CHECK(console_cmd_start());    // Start console
+    ```
+
+### Adding a plugin command or component:
+To add a plugin command or any component from IDF component manager into your project, simply include an entry within the `idf_component.yml` file.
+
+For more details refer [IDF Component Manager](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/tools/idf-component-manager.html)
+
+
+## Suported command:
+
+### Ifconfig:
+```
+ ifconfig help: Prints the help text for all ifconfig commands
+ ifconfig netif create/destroy <ethernet handle id>/<iface>: Create or destroy a network interface with the specified ethernet handle or interface name
+ ifconfig eth init/deinit/show: Initialize, deinitialize and display a list of available ethernet handle
+ ifconfig: Display a list of all esp_netif interfaces along with their information
+ ifconfig <iface>: Provide the details of the named interface
+ ifconfig <iface> default: Set the specified interface as the default interface
+ ifconfig <iface> ip6: Enable IPv6 on the specified interface
+ ifconfig <iface> up: Enable the specified interface
+ ifconfig <iface> down: Disable the specified interface
+ ifconfig <iface> link <up/down>: Enable or disable the link of the specified interface
+ ifconfig <iface> napt <enable/disable>: Enable or disable NAPT on the specified interface.
+ ifconfig <iface> ip <ipv4 addr>: Set the IPv4 address of the specified interface
+ ifconfig <iface> mask <ipv4 addr>: Set the subnet mask of the specified interface
+ ifconfig <iface> gw <ipv4 addr>: Set the default gateway of the specified interface
+ ifconfig <iface> staticip: Enables static ip
+ ifconfig <iface> dhcp server <enable/disable>: Enable or disable the DHCP server.(Note: DHCP server is not supported yet)
+ ifconfig <iface> dhcp client <enable/disable>: Enable or disable the DHCP client.
+Note: Disabling the DHCP server and client enables the use of static IP configuration.
+```
+
+## Usage:
+
+### Creating an ethernet interface
+```
+esp> ifconfig eth init
+Internal(IP101): pins: 23,18, Id: 0
+esp> ifconfig netif create 0
+```
+
+### Removing an interface and deinitializing ethernet
+```
+esp> ifconfig netif destroy en1
+I (8351266) ethernet_init: Ethernet(IP101[23,18]) Link Down
+I (8351266) ethernet_init: Ethernet(IP101[23,18]) Stopped
+esp> ifconfig eth deinit
+```
+
+### Set default interface
+```
+esp> ifconfig en1 default
+```
+
+### Enable NAPT on an interface
+```
+esp> ifconfig en1 napt enable
+I (8467116) console_ifconfig: Setting napt enable on en1
+```
+
+### Enable DHCP client on an interface
+```
+esp> ifconfig en1 dhcp client enable
+```
+
+### Enable static IP on an interface
+```
+esp> ifconfig en1 dhcp client disable
+```
+
+### Set static IP address
+```
+esp> ifconfig en1 ip 192.168.5.2
+I (111466) console_ifconfig: Setting ip: 192.168.5.2
+esp> ifconfig en1 mask 255.255.255.0
+I (130946) console_ifconfig: Setting mask: 255.255.255.0
+esp> ifconfig en1 gw 192.168.5.1
+I (143576) console_ifconfig: Setting gw: 192.168.5.1
+I (143576) esp_netif_handlers: eth ip: 192.168.5.2, mask: 255.255.255.0, gw: 192.168.5.1

+# Console command wifi
+The component offers a console with a command that enables runtime wifi configuration for any example project.
+
+## API
+
+### Steps to enable console in an example code:
+1. Add this component to your project using ```idf.py add-dependency``` command.
+2. In the main file of the example, add the following line:
+    ```c
+    #include "console_wifi.h"
+    ```
+3. Ensure esp-netif and NVS flash is initialized and default event loop is created in your app_main():
+    ```c
+    ESP_ERROR_CHECK(esp_netif_init());
+    ESP_ERROR_CHECK(esp_event_loop_create_default());
+    esp_err_t ret = nvs_flash_init();   //Initialize NVS
+    if (ret == ESP_ERR_NVS_NO_FREE_PAGES || ret == ESP_ERR_NVS_NEW_VERSION_FOUND) {
+        ESP_ERROR_CHECK(nvs_flash_erase());
+        ret = nvs_flash_init();
+    }
+    ESP_ERROR_CHECK(ret);
+    ```
+4. In your app_main() function, add the following line as the last line:
+    ```c
+    ESP_ERROR_CHECK(console_cmd_init());     // Initialize console
+
+    // Register all plugin command added to your project
+    ESP_ERROR_CHECK(console_cmd_all_register());
+
+    // To register only wifi command skip calling console_cmd_all_register()
+    ESP_ERROR_CHECK(console_cmd_wifi_register());
+
+    ESP_ERROR_CHECK(console_cmd_start());    // Start console
+    ```
+
+## Suported command:
+
+### wifi:
+* ```wifi help```: Prints the help text for all wifi commands
+* ```wifi show network```: Scans and displays upto 10 available wifi networks.
+* ```wifi show sta```: Shows the details of wifi station.
+* ```wifi sta join <network ssid> <password>```: Station joins the given wifi network.
+* ```wifi sta join <network ssid>```: Station joins the given unsecured wifi network.
+* ```wifi sta leave```: Station leaves the wifi network.

+# Target test running OTA update
+
+## Overview
+
+The aim of this test is to exercise the most commonly failing scenario, running OTA over PPPoS with https.
+
+This project opens a data session, runs basic mqtt operations and initiates OTA update.
+It supports the following test configurations:
+* Using a real modem device (default config)
+* Using VFS device (only to exercise VFS DTE)
+* Using network-only DCE (connecting directly to PPP server) -- needs some configuration
+
+### Configuring the PPP server
+
+You need to run these applications on your host machine:
+* PPP server
+```bash
+sudo pppd /dev/ttyUSB1 115200 192.168.11.1:192.168.11.2 ms-dns 8.8.8.8 modem local noauth debug nocrtscts nodetach +ipv6
+```
+* MQTT broker: Running mosquitto in the default config is enough, configuring the broker's URL to the local PPP address: `config.broker.address.uri = "mqtt://192.168.11.1";`
+* HTTP server: Need to support HTTP/1.1 (to support ranges). You can use the script `http_server.py` and configure the OTA endpoint as `"https://192.168.11.1:1234/esp32.bin"`
+
+## Potential issues
+
+When running this test it is expected to experience some buffer overflows or connection interruption.
+The modem library should recover from these failure modes and continue and complete OTA update.
+These issues are expected, since UART ISR is deliberately not placed into IRAM in the test configuration to exhibit some minor communication glitches.

 - ``examples/modem_console`` is an example to exercise all possible module commands in a console application.
 - ``examples/ap_to_pppos`` this example focuses on the network connectivity of the esp-modem and provides a WiFi AP that forwards packets (and uses NAT) to and from the PPPoS connection.
 
+Working modes
+~~~~~~~~~~~~~
+
+Modem devices could work in multiple different modes, esp-modem library
+uses these states to describe them:
+- Standard modes:
+      - Command mode -- This mode is used for sending AT commands
+      - Data or PPP mode -- This mode is used for data communication (to create PPPoS tunnel between the device and the library)
+- Multiplexing modes:
+      - CMUX mode -- This mode creates two virtual channels and uses one for sending AT commands and the other one for data communication.
+      - DUAL mode -- This mode uses two physical channels the same way as CMUX. This mode is supported only by certain devices, usually with USB interface.
+- Manual CMUX modes -- These modes are designed for applications to have better control over CMUX mode transitions. It allows setting up the virtual channels,
+  switching between channels, transitioning between data and command modes for each channel separately, and exiting the CMUX.
+
+Switching between common modes
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The diagram below depicts allowed transitions between the most common modes
+
+::
+
+      +---------+    +---------+
+      | COMMAND |<-->|   DATA  |
+      +---------+    +---------+
+           ^
+           |
+           v
+      +-------+
+      | CMUX  |
+      +-------+
+
+Note that it is possible to switch from any mode to the "UNDEF" mode and vice-versa.
+
+Switching between manual modes
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The diagram below depicts allowed transitions between manual CMUX modes
+
+::
+                             +------------------------------------
+                             |                                   |

+      | MANUAL   |           |                             |  MANUAL  |

+           +-----------------------------------------------------+
+
+Note that transitioning between "MANUAL_DATA" and "MANUAL_CMD" switches the secondary terminal (dedicated to PPP session) and could be used for recovering data communication if PPP session gets dropped.
