## How to access the Firmware Settings
|
||||
|
||||
To access the firmware settings, the Scoppy app must have established a connection to the Scoppy firmware on the Pico W (ie. the connection badge at the lower left of the app screen should show a status of _OK_). For help with this see [Getting started with Scoppy and the Pico W](../wiki/Getting-started-with-the-Pico-W).
|
||||
|
||||
Tap the connection badge at the the lower left of the screen and then tap _Connected device_ and then _Firmware settings_.
|
||||
|
||||
## Settings
|
||||
|
||||
### Device Name
|
||||
|
||||
The unique identifer of the device. Used with the _Scoppy device name_ connection method<sup>1</sup>. It is unlikely that you'll want to change this.
|
||||
|
||||
### Wi-Fi Country
|
||||
|
||||
For optimum compatibility with your other Wi-Fi equipment select your country.
|
||||
|
||||
### Wi-Fi Mode
|
||||
|
||||
#### Access Point
|
||||
|
||||
The Pico W will function an access point. To connect with the Scoppy app you'll need to select the SCOPPY network in Android Settings (Connections -> Wi-Fi)
|
||||
|
||||
##### AP SSID
|
||||
|
||||
The SSID of the Pico W when operating in access point mode.
|
||||
|
||||
##### AP Password
|
||||
|
||||
The password of the Pico W access point.
|
||||
|
||||
##### AP Authorization Type
|
||||
|
||||
The authorization method used when the Pico W is in access point mode.
|
||||
|
||||
#### Station/Client
|
||||
|
||||
The Pico W will function as a Wi-Fi station (aka client). In other words, it will connect to your network just like any other device. This is probably the mode you want.
|
||||
|
||||
##### SSID
|
||||
|
||||
The SSID of your network's Wi-Fi access point (or router or modem if these incorporate an access point)
|
||||
|
||||
##### Password
|
||||
|
||||
The password used by your network's access point. This might also be referred to as a key.
|
||||
|
||||
##### Authorization Type
|
||||
|
||||
The method of security used by your access point. You should be able to find this in your access point's settings. If in doubt use WPA2/WPA Mixed which should work on most networks.
|
||||
|
||||
##### Scoppy Access Code
|
||||
|
||||
Use this used to restrict who can access the Pico W when in station/client mode. See [Wi-Fi Connection Settings](../app-help/WiFi-Connection-Settings) for more information about connecting using an access code.
|
||||
|
||||
You will most probably want to leave this field blank.

## How to access the Wi-Fi connection settings
|
||||
|
||||
Tap the connection badge at the the lower left of the screen and then tap _Connection settings_. This menu item will only be visible when Wi-Fi is selected as the connection type. To change the connection type, tap the connection badge and then tap _Change connection type_.
|
||||
|
||||
|
||||
## Connection Methods
|
||||
|
||||
The following connection methods apply when the Pico W is in _client/station mode_. If the Pico W is in _access point mode_ then the app will connect automatically.
|
||||
|
||||
### Auto
|
||||
The app will try and connect to the first Pico W (with the Scoppy firmware installed) that it finds on the network. If another phone/tablet has already established a connection with the Pico W then the connection will fail.
|
||||
|
||||
Use this setting if there is only one Pico W (with the Scoppy firmware) that is on the network.
|
||||
|
||||
### Scoppy device name
|
||||
Using this option you can select which Pico W to connect to. Tap the Search button to find Pico Ws on the network.
|
||||
|
||||
### IP address
|
||||
If you know the IP address of the Pico W (eg. if you have setup a fixed MAC/IP mapping on your router) then you can enter it here.
|
||||
|
||||
Note 1. The Pico W only obtains its IP address via DHCP - you cannot set a fixed address in the firmware.
|
||||
|
||||
Note 2. The MAC address of a connected Pico W can be found via the connection menu in the app and tapping _Connected device_ and _About device_. The MAC address is also written to the serial output when the Pico W starts up.
|
||||
|
||||
### Access Code
|
||||
Use this option if you have multiple Pico Ws on the network and want to control who can access each one. The access code must also be entered in the
|
||||
firmware settings. Once a Pico W is assigned an access code (and has been restarted) then it can't be connected to via the _Auto_ and _Scoppy device name_ connection methods (but the IP address method will still work - as will connecting via USB).
|
||||
|
||||
The same access code should not be used on different Pico Ws on the network.
|
||||
|
||||
Note: it can take a while for this option to take effect because the previous connection information is cached by Android for a period of time.

The Scoppy firmware on the Pico W can connect to your Android phone/tablet via USB or via Wi-Fi. When connecting via Wi-Fi,
|
||||
the Pico W can be configured as either an access point or as a Wi-Fi client (AKA station).
|
||||
|
||||
The first thing that you will probably want to do is to configure the Pico W as a client/station so that it can connect to your local network.
|
||||
The procedure for doing this is described below.
|
||||
|
||||
## Initial setup
|
||||
|

### How to select a device to connect to when there is more than one Pico W on the network
|
||||
|
||||
Use the _Scoppy device name_ connection method. See [Wi-Fi Connection Settings](../app-help/WiFi-Connection-Settings).
|
||||
|
||||
### How prevent other people on the network from connecting to a Pico W device
|
||||
|
||||
Use the _Access Code_ connection method. See [Wi-Fi Connection Settings](../app-help/WiFi-Connection-Settings).
|
||||
|
||||
### How to connect to a Pico W via USB
|
||||
|
||||
Ensure the connection type is set to USB (tap the connections badge at the lower left of the screen if it is not). You will have 10 seconds to acknowledge the Android USB permissions prompt before the Pico W switches to Wi-Fi mode. Restart the Pico W to try again.
|
||||
|
||||
### Why does the Pico W take more than 10 seconds to connect to my network?
|
||||
|
||||
If the Pico W is connected to an Android device or computer via USB it will try to connect via USB for 10 seconds before switching to Wi-Fi. To prevent this, power
|
||||
the Pico W with a power plug or battery.
|
||||
|
||||
### Why doesn't the LED on my Pico W blink or turn on?
|
||||
|
||||
You've probably installed the Pico (non-wireless) firmware, not the Pico W (wireless) firmware. See the [Installation and Getting Started Guide](Installation-&-Getting-Started).

Wi-Fi 4 (802.11n), Single-band (2.4 GHz)
|
||||
|
||||
#### <sup>2</sup>Connection Sequence
|
||||
|
||||
When it first starts up, the Scoppy firmware will check if the Pico W is connected to an Android device via USB. If so it will try to connect to the Scoppy app
|
||||
via USB. If a connection has not been established within 10 seconds, the firmware will attempt to make a connection via Wi-Fi.
|
||||
|
||||
Note: If the Pico W is powered by the USB port of a computer it may also attempt to connect via USB for a period of 10 seconds before switching to Wi-Fi. For the
|
||||
fastest startup-up time the Pico W should be powered by a 5V DC source without active data lines (eg. a power plug or battery).
|
||||
|
||||
### Wi-Fi LED ###
|
||||
|
||||
A LED can connected to GPIO 14. If this LED is on or blinking then the Scoppy firmware is using Wi-Fi. If the LED is off then the firmware is using USB.
|
||||
|
||||
### Serial output
|
||||
|
||||
The Scoppy firmware will print some diagnostic messages to UART0 on GPIO0 and GPIO1. This will include the current firmware settings. See the section _See "Hello World" UART output_ in the _Getting started with Raspberry Pi Pico_ guide for a primer on how to view the serial output of the Pico W.
