WiFi Processor Module
A WiFi processor module is installed in each Smart Appliance
enabling it to connect to an wireless router, wireless extender,
laptops, tablets, smartphones, and to the Internet.
The WiFi Processor Module combines WiFi Radio and MCU
on a single board and is embedded inside the appliance to
provide the WiFi physical interface.
The WiFi module has ve main funcons:
1. Control the WiFi Radio Module Circuit.
2. Interface to the WIDE/WIN bus.
3. Interface higher data rate data through UART.
4. Contain the Whirlpool standard set of WiFi protocols.
5. Provide a common set of Whirlpool communicaons
applicaons.
WiFi Processor Module Power Requirements
The WiFi Processor Module will have an isolated input supply
of 5 VDC +/- 10%.
WiFi Processor Module Interface
The transceiver must be 802.11 b/g/n compliant.
WiFi Processor Status LED
The WiFi Processor Module has a green and amber LED to
indicate WiFi Module status.
NOTE: Refer to Secon 4: “Diagnoscs & Troubleshoong” for
