WiFi Setup

Through the device's API, you can configure the WiFi network for connected WiFi-enabled devices such as P1603 and P1604. However, in practical applications, this is often insufficient as we frequently need to configure WiFi networks for devices that are not yet connected. Hence, the purpose of this guide is to address this requirement.

Methods of WiFi Network Setup

We utilize different methods for WiFi network setup based on WiFi-enabled devices. Broadly, there are two methods: WiFi setup over SmartConfig and WiFi setup over AP. In both cases, it is necessary to put the device into WiFi configuration mode (refer to the device's user manual for specific instructions).

WiFi setup over SmartConfig

The SmartConfig is a provisioning technology developed by TI to connect a new WiFi device to a WiFi network. It uses a mobile app to broadcast the network credentials from a smartphone, or a tablet, to an un-provisioned WiFi device.

The advantage of this technology is that the device does not need to directly know SSID or password of an Access Point (AP). This information is provided using the smartphone. This is particularly important to headless device and systems, due to their lack of a user interface.

Usage

After the device enters the WiFi Configuration Mode, you can send WiFi configuration to the device directly from your phone/tablet via SmartConfig protocol. Here are Android Demo and iOS Demo。

Supported devices

P1603(Ver.0356 and below)

WiFi setup over AP

After the device enters the WiFi configuration mode, it will open a WiFi hotspot (the SSID is YS_XXXXXXXX, where XXXXXX is related to the ID of device) at the same time. After connecting to the hotspot, your client can send WiFi configuration to the device via HTTP protocol.

Usage

1. The device enters the WiFi configuration mode.
2. The client connects to the WiFi hotspot of the device (no password required).
3. Send the network configuration to the device according to the protocol below.
4. The device exits the WiFi configuration mode.

Protocol

Note: The Host should be the IP address of the device, usually 192.168.4.1.

Get Network Status

Request:

GET /api/v1/network/state

Response:

Content-Type: application/json
Body:
    code: String, The error code; "000000" means success;
    data.wifi.ip： String<Optional>, Current IP address of the WiFi, empty means that the WiFi client is not yet connected to any WiFi network;
    data.wifi.ssid: String<Optional>, The ssid of current WiFi configuration
    data.internet: Bool<Optional>, Whether the device is connected to the Internet；

Scan WiFi Networks

Note:Searching for WiFi networks takes some time, please make the timeout for calling this interface greater than 8 seconds Request:

GET /api/v1/wifi/scan

Response:

Content-Type: application/json
Body:
    code: String, The error code; "000000" means success;
    data[*].ssid： String, SSID of the WiFi network;

Body:
    ssid: String, SSID of target WiFi network；
    pwd: String,  Password of target WiFi network;

Response:

Content-Type: application/json
Body:
    code: String, The error code; "000000" means success;

Exit WiFi Configuration Mode

Note:Call the interface to take the device out of the wiring state. Ths device will also automatically exit the siring state after 4 minutes

Request:

POST /api/v1/wifi/config/exit

Response:

Content-Type: application/json
Body:
    code: String, The error code; "000000" means success;

Supported devices

P1603(Ver.0360 and above),P1604

WiFi setup over AP V2

After the device enters the WiFi configuration mode, it will open a WiFi hotspot (the SSID is YS_XXXXXXXX, where XXXXXX is related to the ID of device) at the same time. After connecting to the hotspot, your client can send WiFi configuration to the device via HTTP protocol.

Usage

1. The device enters the WiFi configuration mode.
2. The client connects to the WiFi hotspot of the device (no password required).
3. Send the network configuration to the device according to the protocol below.
4. The device exits the WiFi configuration mode.

Protocol

Note: The Host should be the IP address of the device, usually 192.168.10.1.
