1 | ANT | Wi-Fi Antenna Note: |
The PSF-XLA module can be used as a 2-way / 5-way dimming device, and users can control it remotely through the APP. The following is the function description:
The blinking mode of the Wi-Fi status light on the device side represents the current network working state of the device. The specific states include the following seven types:
Wi-Fi device state and status light blinks embodiment relationship map
The flashing characteristics of the Wi-Fi status light take 2 seconds as a cycle. As shown in the figure, the low level light is on and the high level light is off. Detailed explanation of each state:
A. Normal: The device works normally, and the connection to the cloud server is normal. At this time, you can control the device through the APP. In any other mode,
Can’t control the device through the APP.
B. NO Wifi: The device cannot connect to the wireless router.
C. No Server: The device is connected to a wireless router, but cannot connect to the server (that is, “Unable to access the Internet” under normal understanding).
D. Unregistered: indicates that the device has not been bound to any account. Generally, the device needs to be bound to the account of E-Link to be able to connect to the cloud server
Communication. You can complete the binding operation by "adding device" in the Yiweilian app.
E. Upgrade: indicates that the device is upgrading firmware.
F. Setting G1: indicates that the device is in compatible pairing mode. The configuration mode is used by the device to obtain the necessary access to the service network provided by the mobile terminal APP
Information, including router ssid, password, server ip, port number, etc.
G. Setting G2: indicates that the device is in quick pairing mode. The configuration mode is used by the device to obtain the necessary access to the service network provided by the mobile terminal APP
Information, including router ssid, password, server ip, port number, etc. The two configurations, the device obtains different information in different ways, see below
Section.
I. Configuration
The device module is an "information island" when it is not connected to the local area network, and the device-side operation cooperates with the settings of the Easy Micro App to enable the device to obtain the joining service
Necessary information for the network, including router ssid, password, server ip, port number, etc. The module has two built-in configuration methods:
For details, please refer to 4.2 Wi-Fi status light flashing mode description) Long press the configuration button 5S, the device enters the compatible pairing mode. Click on Yiweilian APP
Add device (iOS mobile terminal needs to manually connect ssid in the "Settings" menu: ITEAD-10000XXXX, password12345678
The hot Android terminal does not need this operation), enter the ssid and password of the home router to complete the preparation of the device online.
Quick pairing mode: In this mode, the Wi-Fi module is in promiscuous mode (Wi-Fi Promiscuous), and the fast pairing mode is empty: this side
Wi-Fi module is in promiscuous mode (Wi-Fi Promiscuous), and obtains the ssid sent by the mobile terminal in the form of empty and empty packet capture
Encrypted messages such as passwords and passwords. Long press the configuration button 5S in any state of A ~ D mentioned in the previous section, the device enters the quick pairing mode
formula. Click the Yiweilian APP to add the device, enter the ssid and password of the home router, and complete the online configuration of the device.
II. online
The device module needs to go through the following process from power on to server connection:
Join the configured router and connect to the Internet.
Connect to the server.
Register the device and bind it to the e-Link account.
Obtain device application parameters and stay online.
In the above steps, when the connection / acquisition fails, there are corresponding backoff strategies and reconnection mechanisms to ensure that the device is stable and online in real time.
III. upgrade
The module device connects to the upgrade server, downloads and updates to the latest version of firmware, and realizes the online upgrade of the device.
The timer function is configured through the APP, and the timer is divided into the following four types:
PSF-XLA supports timer operation. In order to facilitate customers to use and use it in more scenarios, Yiweilian APP provides four timing modes
formula:
The PSF-XLA module provides customers with two dimming options of 2 and 5 channels. The specific functions are described as follows:
1. Functions supported by 2 channels: warm light and cold light;
2. Functions supported by 5 channels: warm light, cold light, colorful light (red, green and blue);
3. When the 5-way enters the configuration, the breathing lights flash in sequence (cold → warm → red → green → blue);
4. The state of the power switch is consistent with the color brightness and switch before power off;
5. When switching from white light or scene mode to colored light, it will switch to colored red light.
Conditions: VDD = 3.3V ± 10%, GND = 0V; tested at room temperature 25 ° C.

1. 72.2Mbps is measured in 802.11n mode with MCS = 7 and GI = 200uS.
2. Up to + 21.5dBm output power in 802.11b mode.
Note on PCB layout and module layout:
1. Pay attention to the placement of the module during PCB layout, especially the antenna part of the module, as far as possible away from interference sources: magnetic components (such as motors, electrical
Sense, transformers, etc.), high-frequency signal devices (such as crystal oscillators, high-frequency clock signals, etc.).
2. The upper and lower layers of the PCB where the module is placed should not be routed as much as possible, do copper clad treatment, and the antenna from the module to the PCB of the nearest pin part of the module can be
Can be hollowed out.
3. The area of the module PCB antenna and the area of 15 mm expansion need to be cleared (copper, wire, and components are strictly prohibited), refer to the following figure:
4. The power supply (VCC) pin capacitance of the module and the other pin capacitance and resistance of the module should be placed as close as possible to the module pins, and the wiring path should be short.
