Support hardware flow control RTS and CTS. Figure 3-2 UART communication As shown in figure 3-2, the sent data is written to the TX buffer, and the UART module transfers the data from the TX buffer through the TX foot When transferred to other devices, the data received by the RX foot is first sent to the RX buffer and then read through the MCU or DMA. If the UART's RX buffer is full, the UART module will send a signal (configurable high or low) through the RTS foot, informing other devices that it should stop sending data.Similarly, UART receives CTS foot signal. Indicates that the RX buffer of other devices is close to full, and UART should stop sending data. 2019.09 www.wi-linktech.com 10 Wi-linktechCommunicationTechnologies(Shanghai)Co.,Ltd 4.

(mm). 2019.09 www.wi-linktech.com 12 4.3 Matters needing attention Wi-linktechCommunicationTechnologies(Shanghai)Co.,Ltd Bluetooth works at the frequency of 2402-2480MHz, so we should try to avoid the influence of various factors on wireless transceiver. Please note the following points:
Avoid the use of metal in the product enclosure that surrounds the module. If the enclosure is metal, an external antenna should be considered. The metal screws inside the product should be kept away from the RF part of the module. To maximize RF performance, the user's motherboard layout should follow the following recommendations:
1) Antenna clearance area: the user's main board directly below the antenna area of the module shall not have any copper foil wiring (including power, ground and signal layers). 2) Module location: modules should ideally be arranged in one corner of the user's main board,with the PCB antenna located at the far end of the main board.This position minimizes the clearance area of the antenna.
(Refer to the definition of antenna clearance area in the figure below) Figure 4-3 Keep out 2019.09 www.wi-linktech.com 13 Wi-linktechCommunicationTechnologies(Shanghai)Co.,Ltd 5. Reflux parameter recommendation Backflow parameters can refer to the following Settings:

Regulatory Module Integration Instructions List of applicable FCC rules This device complies with part 15.247 of the FCC Rules. Limited module procedures Not applicable Summarize the specific operational use conditions This module can be applied in remote control toys, sports and fitness sensors , health sensors, mobile accessories as well as smart home. The input voltage to the module should be nominally 1.8-4.3 V DC typical value 3.3V DC and the ambient temperature of the module should not exceed 85. Trace antenna designs Not applicable RF exposure considerations The equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator and your body. If the equipment built into a host as a portable usage, the additional RF exposure evaluation may be required as specified by 2.1093. Antennas This module using PCB antenna with maximum gain is 3 dBi . 2019.09 www.wi-linktech.com 15 Wi-linktechCommunicationTechnologies(Shanghai)Co.,Ltd Label and compliance information An exterior label on OEMs end product can use wording such as the following:
Contains Transmitter Module FCC ID: 2AOO6-WLT8016 or Contains FCC ID: 2AOO6-WLT8016 Information on test modes and additional testing requirements a) The modular transmitter has been fully tested by the module grantee on the required number of channels modulation types and modes it should notbe necessary for the host installer to re-test all the available transmitter modes or settings. It is recommended that the host product manufacturer installing the modular transmitter perform some investigative measurements toconfirmthat the resulting composite system does not exceed the spurious emissions limits or band edge limits (e.g. where a different antenna may be causing additional emissions). b) The testing should check for emissions that may occur due to the intermixing of emissions with the other transmitters digital circuitry or due to physical properties of the host product (enclosure). This investigation is especially important when integrating multiple modular transmitters where the certification is based on testing each of them in a stand-alone configuration. It is important to note that host product manufacturers should not assume that because themodular transmitter is certified that they do not have any responsibility for final product compliance. c) If the investigation indicates a compliance concern the host product manufacturer is obligated to mitigate the issue. Host products using a modular transmitter are subject to all the applicable individual technical rules as well as to the general conditions of operation in 2019.09 www.wi-linktech.com 16 Wi-linktechCommunicationTechnologies(Shanghai)Co.,Ltd Sections 15.5 15.15 and 15.29 to not cause interference. The operator of the host product will be obligated to stop operating the device until the interference has been corrected The WLT8016 module is based on FR8016HA chip .support standard Bluetooth 5.0 commands. For the testing module on your product, user can refer to specification of the Bluetooth system on how to configure and evaluate the module.This specification can also be found on the official Bluetooth website:
tions. https://www.bluetooth.org/enus/specification/adoptedspecifica Additional testing Part 15 subpart B disclaimer The final host / module combination need to be evaluated against the FCC Part 15B criteria for unintentional radiators in order to be properly authorizedfor operation as a Part 15 digital device . The host integrator installing this module into their product must ensure that the final composite product complies with the FCC requirements by a technical assessment or evaluation to the FCC rules including the transmitter operation and should refer to guidance in KDB 996369. Frequency spectrum to be investigated For host products with certified modular transmitter the frequency range of investigation of the composite system is specified by rule in Sections 15.33(a)(1) through (a)(3) or the range applicable to the digital device asshown in Section 15.33(b)(1) whichever is the higher frequency range of investigation. Operating the host product When testing the host product all the transmitters must be operating.The transmitters can be enabled by using publicly-available drivers and turned on so the transmitters are active. In certain 2019.09 www.wi-linktech.com 17 Wi-linktechCommunicationTechnologies(Shanghai)Co.,Ltd conditions it might be appropriate touse a technology-specific call box
(test set) where accessory devices or drivers are not available. When testing for emissions from the unintentional radiator the transmitter shall be placed in the receive mode or idle mode if possible. If receive mode only is not possible then the radio shall be passive
(preferred) and/or active scanning. In these cases this would need to enable activity on the communication BUS (i.e. PCIe SDIO USB) to ensure the unintentionalradiator circuitry is enabled. Testing laboratories may need to add attenuation or filters depending on the signal strength of any active beacons (if applicable) from the enabled radio(s). See ANSI C63.4 ANSI C63.10 and ANSI C63.26 for further general testing details. The product under test is placed into a normal paired' mode with another BLE device as per the normal intended use of the product (for example transferring data). FCC Statement Any Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. This 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. 2019.09 www.wi-linktech.com 18
