+# MQTT application running on WiFi station
+
+This is a simple mqtt demo, that connects to WiFi AP first. This application has a dependency to `esp_wifi_remote`, so that if it's build and executed on a chipset without WiFI capabilities it redirects all wifi calls the remote target.
+
+## Overview
+
+When running this example on a target that doesn't natively support WiFi, please make sure that the remote target (slave application) is connected to your chipset via the configured transport interface.
+
+Connection to the slave device also depends on RPC library used. It is recommended to use [`esp_hosted`](https://github.com/espressif/esp-hosted). Alternatively you can use [`eppp_link`](https://components.espressif.com/components/espressif/eppp_link).
+
+Please note, that `esp_hosted` as a component is currently WIP, so the `wifi_remote` defaults to `eppp`, for now.
+
+## HW connection
+
+We currently support only `UART` transport, so the connection is very simple. You only need to connect Rx, Tx and GND with the remote target.
+You need to configure these fields according to your connection:
+* CONFIG_ESP_WIFI_REMOTE_EPPP_UART_TX_PIN
+* CONFIG_ESP_WIFI_REMOTE_EPPP_UART_RX_PIN
+
+## SW configuration
+
+The RPC mechanism between the host and the slave micro uses TLS with mutual authentication, so you would have to configure certificates and keys for both parties. This application -- host target -- is considered RPC client, so it needs client's certificate and key, as well as the CA certificate to validate the server (slave application).
+If self-signed certificates are acceptable, you can use [generate_test_certs](../test_certs/generate_test_certs.sh) script to generate both the CA and the keys itself and convert them to the PEM format that's accepted by the EPPP RPC engine.
+You will have to configure these options:
+* CONFIG_ESP_WIFI_REMOTE_EPPP_SERVER_CA
+* CONFIG_ESP_WIFI_REMOTE_EPPP_CLIENT_CRT
+* CONFIG_ESP_WIFI_REMOTE_EPPP_CLIENT_KEY
+
+## Setting up slave device
+
+You need to set up the connection and configuration in a similar way on the slave part (connection pins + certificates and keys). Please refer to the [slave_application](../server/README.md) README for more information.
