+# Easy Connect - Easily add all supported connectivity methods to your mbed OS project
+
+You may want to give the users of your application the possibility to switch between connectivity methods. The `NetworkInterface` API makes this easy, but you still need a mechanism for the user to chooce the method,  and perhaps throw in some `#define`'s. Easy Connect handles all of this for you. Just declare the desired connectivity method in your `mbed_app.json` file and call `easy_connect()` from your application.
+
+## Specifying the connectivity method
+
+Add the following to your `mbed_app.json` file:
+
+```json
+{
+    "config": {
+        "network-interface":{

+
+If you select `ETHERNET` with `UBLOX_ODIN_EVK_W2` you must add this to your `target-overrides` section in `mbed_app.json`:
+
+```json

+            "target.device_has_remove": ["EMAC"]
+            }
+```
+
+If you select `WIFI_ESP8266`, `WIFI_IDW0XX1`, `WIFI_ODIN` or `WIFI_RTW`, you also need to add the WiFi SSID and password:
+
+```json
+    "config": {
+        "network-interface":{
+            "help": "options are ETHERNET, WIFI_ESP8266, WIFI_IDW0XX1, WIFI_ODIN, WIFI_RTW, MESH_LOWPAN_ND, MESH_THREAD, CELLULAR_ONBOARD",

+        "wifi-password": {
+            "value": "\"Password\""
+        }
+    }
+```
+
+If you use `MESH_LOWPAN_ND` or `MESH_THREAD` you need to specify your radio module:
+
+```json
+    "config": {
+        "network-interface":{
+            "help": "options are ETHERNET, WIFI_ESP8266, WIFI_IDW0XX1, WIFI_ODIN, WIFI_RTW, MESH_LOWPAN_ND, MESH_THREAD, CELLULAR_ONBOARD",

+        	"value": "ATMEL"
+        }
+    }
+```
+
+If you use `CELLULAR_ONBOARD` (for which user documentation can be found [here](https://docs.mbed.com/docs/mbed-os-api-reference/en/latest/APIs/communication/cellular/)) you must specify the following:
+
+```json
+    "target_overrides": {
+        "*": {
+            "ppp-cell-iface.apn-lookup": true
+        }
+    }
+```
+...and you may also need to specify one or more of the following:
+
+```json
+    "config": {
+        "cellular-apn": {
+            "help": "Please provide the APN string for your SIM if it is not already included in APN_db.h.",
+            "value": "\"my_sims_apn\""
+        },
+        "cellular-username": {
+            "help": "May or may not be required for your APN, please consult your SIM provider.",
+            "value": "\"my_sim_apns_username\""
+        },
+        "cellular-password": {
+            "help": "May or may not be required for your APN, please consult your SIM provider.",
+            "value": "\"my_sim_apns_password\""
+        },
+        "cellular-sim-pin": {
+            "help": "Please provide the PIN for your SIM (as a four digit string) if your SIM is normally locked",
+            "value": "\"1234\""
+        }
+    }
+```
+
+None of the optional settings need to be specified for the `UBLOX_C030_U201` cellular target, for which the APN settings are in `APN_db.h`.
+
+## Using Easy Connect from your application
+
+Easy Connect has just one function that returns either a `NetworkInterface`-pointer or `NULL`:
+
+```cpp
+#include "easy-connect.h"
+
+int main(int, char**) {
+    NetworkInterface* network = easy_connect(true); /* has 1 argument, enable_logging (pass in true to log to serial port) */
+    if (!network) {
+        printf("Connecting to the network failed... See serial output.\r\n");
+        return 1;
+    }
+
+    // Rest of your program
+}
+```
+
+## Configuration examples
+
+There are many things that you have to modify for all of the combinations. Examples for configurations are available for example in the [mbed-os-example-client](https://github.com/ARMmbed/mbed-os-example-client/tree/master/configs) repository.
+
+## Compilation error NanostackRfPhyAtmel.cpp
+
+If you encounter a compilation error such as below, you need to add an `.mbedignore` file that tells the mbed compiler to skip compiling the files that require Nanostack. By default, the mbed compiler compiles every single file from all folders.
+
+```
+Scan: env
+Compile [  0.2%]: NanostackRfPhyAtmel.cpp
+[Fatal Error] NanostackRfPhyAtmel.cpp@18,44: nanostack/platform/arm_hal_phy.h: No such file or directory
+[ERROR] ./easy-connect/atmel-rf-driver/source/NanostackRfPhyAtmel.cpp:18:44: fatal error: nanostack/platform/arm_hal_phy.h: No such file or directory
+ #include "nanostack/platform/arm_hal_phy.h"
+                                            ^
+compilation terminated.
+
+```
+
+An example of a suitable `.mbedignore` file is available in the [mbed-os-example-client](https://github.com/ARMmbed/mbed-os-example-client/tree/master/configs) repository.
+
+## Linking error with UBLOX_EVK_ODIN_W2
+
+If you get a linking error such as below, you are compiling the `WIFI_ODIN` with the `EMAC override` section in `mbed_app.json`. Remove the `EMAC override` from your `mbed_app.json`. 
+
+```
+Link: tls-client
+./mbed-os/targets/TARGET_STM/TARGET_STM32F4/TARGET_UBLOX_EVK_ODIN_W2/sdk/TOOLCHAIN_GCC_ARM/libublox-odin-w2-driver.a(OdinWiFiInterface.o): In function `OdinWiFiInterface::handle_wlan_status_started(wlan_status_started_s*)':

+collect2: error: ld returned 1 exit status
+
+[mbed] ERROR: "/usr/bin/python" returned error code 1.
+```
+
+## Network errors
+
+If Easy Connect cannot connect to the network, it returns a network error with an error code. To see what the error code means, see the [mbed OS Communication API](https://os.mbed.com/docs/latest/reference/network-socket.html).
+
+## CR/LF in serial output
+
+If you want to avoid using `\r\n` in your printouts and just use normal C style `\n` instead, please specify these to your `mbed_app.json`:
+
+```json
+       "target_overrides": {
+        "*": {
+            "platform.stdio-baud-rate": 115200,
+            "platform.stdio-convert-newlines": true
+        }
+    }
+```
+
+## Extra defines
+
+If you'd like to use Easy Connect with mbed Client then you're in luck. Easy Connect automatically defines the `MBED_SERVER_ADDRESS` macro depending on your connectivity method (either IPv4 or IPv6 address). Use this address to connect to the right instance of mbed Device Connector.
