Function description
HLW3215-TG is a Wi-Fi module used in home appliances, and the first batch of home appliances
are dishwasher and oven. The module is implemented by HL3215STG core board + expansion
board, which is provided to customers in the form of modules.The hardware and software
architecture based on the module can realize the networking and the control of home appliances.
Dishwasher and oven are controlled by the module to achieve their local control functions. They
are connected to the cloud server through Wi-Fi and Bluetooth. Users can control the dishwasher
and oven through the mobile terminal App to achieve remote control, and can connect to the
Hisense Connectlife intelligent platform with intelligent and convenient use experience. In
addition, the module supports OTA upgrades and can also assist in OTA upgrades of the MCU
plate for dishwashers and ovens.
We will retain control over the final installation of the modular such that compliance of the end
product is assured. If any hardware modify or RF control software modify will be made by host
manufacturer, C2PC or new certificate should be apply to get approval,if those change and
modification made by host manufacturer not expressly approved by the party responsible for
compliance ,then it is illegal.
