General Functions
The wireless module is a highly integrated single-chip low power single
bands(2.4GHz) Wireless LAN(WLAN) and Bluetooth Low Energy(BLE 5.0)
communication controller.It consists of a high performance MCU
(Armv8-M,Cortex-M33 instruction set compatible) called Real-M300(or KM4
thereafter) and a lower MCU (Armv8-M,Cortex-M23 instruction set compatible)
called Real-M200(or KM0 thereafter),WLAN(802.11b/g/n)MAC,an 1T1R capable WLAN
baseband,RF,Bluetooth and peripherals.
This compact module is a total solution for a combination of Wi-Fi 802.11b/g/n
technologies with Microcontroller Processor. The module is specifically
developed for embedded system devices. Detailed Instruction of WiFi+BLE
module.
Hereby, GREE Electric Appliances, Inc. of Zhuhai, declares that this WiFi+BLE
module is in compliance with the essential requirements and other relevant
provisions of RE Directive 2014/53/EU. A copy of the full DoC is attached.

3.3 Connect device to network
Operation method for adding devices: Click icon “+” in the top right corner of
the main interface in figure 1, click to select” air conditioner” device in
figure 2, reset wireless gateway (click RESET button for 5s), and then click
“Next” in the figure 4. Automatically search home WiFi as shown in figure 5,
input password of home WiFi, and click “Search device” for configuration. The
interface with completed configuration is shown in figure 6.
Or click “Manual Add” in the top right corner and then reset the air
conditioner according to the prompt. After energization, select the wireless
network of control device, confirm home WiFi and then configure the network.
When device is added successfully, pull down the device list page on GREE+APP to refresh it and then the added devices will be displayed. If it’s not displayed, please check the network and confirm whether the device is added successfully. On the device list page, simple management and control for the device is available. As for configuration method for adding devices, you can also refer to official instruction of GREE+APP http://www.gree.com/greeplus/index.html?from=timeline.
FCC KDB 996369 D03 for module certification:
- List of applicable FCC rules and Canada rules: The module complies with FCC Part 15.247, and Canada RSS-247.
- Summarize the specific operational use conditions: The module has been certified for Fix/Mobile applications. The host product operating conditions must be such that there is a minimum separation distance of 20 cm (or possibly greater than 20 cm) between the antenna radiating structures and nearby persons. The host manufacturer is obligated to confirm the use conditions of the host product to ensure that distance specified in the instructions is met. In this case the host product is classified as either a mobile device or a fixed device for RF exposure purposes. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
- Limited module procedures: Not applicable.
- Trace antenna designs: Not applicable.
- RF exposure considerations: This equipment complies with FCC’s and IC’s RF radiation exposure limits set forth for an uncontrolled environment. The antenna(s) used for this transmitter must be installed and operated to provide a separation distance of at least 20 cm from all persons and must not be collocated or operating in conjunction with any other antenna or transmitter. Installers must ensure that 20cm separation distance will be maintained between the device and users.
- Antennas:
Type| Gain| Impedance| Application| Min
Separation
---|---|---|---|---
PCB type
Antenna| 1.57dBi| 50Ω| Fixed| 20 cm
The antenna is permanently attached, can’t be replaced.

Label and compliance information: his device complies with part 15 of the FCC rules. Operation is subject to the following two conditions:
(1) this device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that may cause undesired operation.
NOTE: The manufacturer is not responsible for any radio or TV interference caused by unauthorized modifications or changes to this equipment. Such modifications or changes could void the user’s authority to operate the equipment.
Warning: Changes or modifications to this unit not expressly approved by the party responsible for compliance could voidthe user’s authority to operate the equipment.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does causeharmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
ISED statements:
This device contains licence-exempt transmitter(s)/receiver(s) that comply with Innovation, Science and Economic Development Canada’s licence-exempt RSS(s). Operation is subject to the following two conditions:
(1) This device may not cause interference.
(2) This device must accept any interference, including interference that may cause undesired operation of the device.
The system integrator must place an exterior label on the outside of the final product housing theGRJW05-J3 Modules. Below is the contents that must be included on this label. OEM Labeling Requirements:
NOTICE: The OEM must make sure that FCC labeling requirements are met. This includes a clearly visible exterior label on the outside of the final product housing that displays the contents shown in below:
Contains FCC ID: 2ADAP-GRJW05J6
Contains IC: 12478A- GRJW05J6 -
Information on test modes and additional testing requirements: When testing host product, the host manufacture should follow FCC KDB Publication 996369 D04 Module Integration Guide for testing the host products. The host manufacturer may operate their product during the measurements. In setting up the configurations, if the pairing and call box options for testing does not work, then the host product manufacturer should coordinate with the module manufacturer for access to test mode software. For wireless LAN, the product under test is set into a link/association with a partnering WLAN device, as per the normal intended use of the product. To ease testing, the product under test is set to transmit at a high duty cycle, such as by sending a file or streaming some media content. Alternatively, a Wi-Fi test set may be used. Simultaneously transmitting modules installed in the host should be all active.
