Overview

The WLT8018M is a Bluetooth Low Power through-pass module from Valentone. The module is mainly used in the Internet of Things data communication, through a wealth of peripheral interfaces to implement data acquisition and control. In transparent transmission mode, the user’s product can quickly dock with the module and communicate with the mobile device to realize the intelligent control and management of the product.
The WLT8018M is based on the Bluetooth Low Power 5.0 protocol, which can be used for transparent and encrypted point-to-point data transmission. Users do not need to care about the transmission protocol, and only need to make simple Settings to communicate.
The module supports BLE (Up to Bluetooth 5.0) and BLE Mesh. Dynamic stack and protocol Profile configuration are supported, and product features can be configured via software, providing the ultimate flexibility. It also supports hardware OTA upgrades, allowing convenient product features to be rolled out and upgraded.

Reference Design

4.1. Outline dimensions of the module

Table 4-1: Module design dimensions

Note: Verentone reserves the right to select components from different suppliers to realize the functions of the module. At the same time, ensure that all mechanical and electrical specifications and module certifications are maintained. The design should be carried out within the scope of the physical dimensions of the machinery as shown in Figure 5-2. All measurements are in millimeters (mm).

4.2. Precautions
Bluetooth working at 2.4GHz frequency, should try to avoid various factors on the wireless transceiver impact, pay attention to the following points:

• Avoid metal for the part of the product housing that encloses the module, and if the housing is metal, consider using an external antenna.
  Metal screws, etc. inside the product should be kept away from the RF portion of the module.

• In order to maximize RF performance, the user motherboard layout should follow the following recommendations:

• Antenna clearance area: The user motherboard located directly below the antenna area of the module must not have any copper foil wiring (including power, ground, signal layers).

• Module location: The module should ideally be arranged in a corner of the user’s motherboard, with the PCB antenna located at the far end of the motherboard. This position minimizes the headroom area for the antenna.
