# enduser setup Module
This module provides a simple way of configuring ESP8266 chips without using a serial interface or pre-programming WiFi credentials onto the chip.
![enduser setup config dialog](../../img/enduser-setup.jpg "enduser setup config dialog")
After running [`enduser_setup.start()`](#enduser_setupstart) a portal like the above can be accessed through a wireless network called SetupGadget_XXXXXX. The portal is used to submit the credentials for the WiFi of the enduser.
After an IP address has been successfully obtained this module will stop as if [`enduser_setup.stop()`](#enduser_setupstop) had been called.
## enduser_setup.manual()
Controls whether manual AP configuration is used.
By default the `enduser_setup` module automatically configures an open access point when starting, and stops it when the device has been successfully joined to a WiFi network. If manual mode has been enabled, neither of this is done. The device must be manually configured for `wifi.SOFTAP` mode prior to calling `enduser_setup.start()`. Additionally, the portal is not stopped after the device has successfully joined to a WiFi network.
Most importantly, *the `onConfigured()` callback is not supported in manual mode*. This limitation may disappear in the future.
#### Syntax
`enduser_setup.manual([on_off])`
#### Parameters
- `on_off` a boolean value indicating whether to use manual mode; if not given, the function only returns the current setting.
#### Returns
The current setting, true if manual mode is enabled, false if it is not.
## enduser_setup.start()
Starts the captive portal.
#### Syntax
`enduser_setup.start([onConfigured()], [onError(err_num, string)], [onDebug(string)])`
#### Parameters
- `onConfigured()` callback will be fired when an IP-address has been obtained, just before the enduser_setup module will terminate itself
- `onError()` callback will be fired if an error is encountered. `err_num` is a number describing the error, and `string` contains a description of the error.
- `onDebug()` callback is disabled by default. It is intended to be used to find internal issues in the module. `string` contains a description of what is going on.
#### Returns
`nil`
#### Example
```lua
enduser_setup.start(
function()
print("Connected to wifi as:" .. wifi.sta.getip())
end,
function(err, str)
print("enduser_setup: Err #" .. err .. ": " .. str)
end
);
```
## enduser_setup.stop()
Stops the captive portal.
#### Syntax
`enduser_setup.stop()`
#### Parameters
none
#### Returns
`nil`
