Usage 2.1. Connect to external hardware To apply the M3W Bluetooth serial module to an existing product, connect Tx (Pin 3) to the receive data (RD) pin of the microcontroller as shown in the figure below, and connect the transmit data (TD) pin of the microcontroller to Rx (Pin 4) connect to The M3W model is used when directly connected to the host CPU with 3.3V logic level. M3W Bluetooth Serial Module VCC Tx +3.3V 2 3 4 Rx 5 GND Host Controller Micro-Controller RD TD 2.2. Operation for BR/EDR M3W Bluetooth serial module operates as follows. Standby mode: When power is applied, the internal initialization procedure is carried out and then it enters standby mode and waits for a Bluetooth pairing request from the outside. Bluetooth connection: If there is a Bluetooth pairing request from the outside in standby mode, the pairing operation is performed. The pairing process includes checking whether a legitimate device requests a connection using a 4-digit PIN code. When pairing is established, it enters a mode in which other devices do not accept pairing request (If the connected device supports BT2.1 or higher, SSP is supported. In this case, SSP mode is based on Just Works mode). Data reception: When data is received from the connected Bluetooth device, it is output to the host controller through the Tx (Pin 3) port. Data transmission: When data is input from the Host Controller to the Rx (Pin 4) port, it is transmitted to the connected Bluetooth device. 8 Woosim Systems Inc. 2.3. Operation for Low Energy The M3W Bluetooth serial module operates as follows. Standby mode: Enter into BLE ADVERTISING MODE and execute advertising in low power mode. BLE connection: CENTRAL device detects this and connects BLE LINK. Profiles supported by BLE are as follows. DEVICE INFORMATION PROFILE SERIAL SERVICE Since it supports dual mode operation, 2.2 and 2.3 are supported at the same time. Only one connection is allowed at a time. 3. BLE Operation descript 3.1. BLE setup In BLE and BR/EDR operation, BR/EDR mode operation takes precedence over BLE operation. In other words, it is possible to operate only in BR/EDR mode by turning off the BLE operation if necessary. The method of stopping the operation of BLE can be written by changing the setting of the internal memory (PS KEY) value, and it can also be changed through the UART command when the Bluetooth link is not connected. 3.2. BLE and BR/EDR operation In the state in which BLE operation is enabled, it is discovered as two devices from the outside. (DUAL MODE operation). If a link is connected with priority among BLE or BR/EDR, the other cannot be used. That is, when the BLE link is connected, the BR/EDR link cannot be used, and when the BR/EDR linker is connected, the BLE link cannot be connected. 3.3. BLE service and UUID The services that can be used by connecting BLE are as follows. Device Information Service : This profile is supported by the Bluetooth SIG. In general, general information related to the device can be read. Serial Profile Service : This is an internal profile that is not supported by Bluetooth. According to the recommendation of the Bluetooth SIG, 128 bits UUID is used, and it is divided into two characteristics: transmission and reception.

General The points to be noted when handling the M3W Bluetooth serial module are as follows. When handling the module, provide anti-static measures to avoid damage by static electricity. Use a large enough current source to ensure sufficient current is supplied to the power input stage. Be careful not to input more than the rated power voltage or RF signal. 7.2. RF Performance In order to maximize the RF performance of the product equipped with the M3W Bluetooth serial module, the PCB design should be done with the following considerations in mind. Stable RF performance can be expected only when sufficient ground area is secured on the main PCB. Having objects (conductors or non-conductors) close to the antenna is not good as it interferes with the antenna radiation and distorts the pattern. In the case of conductors, it should be at least 10mm apart from the antenna, and in the case of non-conductors such as plastic fixtures, it should be separated by at least 5mm. The main PCB should be designed so that the ground plane of the main PCB does not invade the antenna beyond the boundary between the module ground plane and the antenna as shown in the figure below. Location of module on the main PCB remove ground on PCB Main PCB board remove ground on PCB Main PCB ground 15 8. Antenna 8.1. General specification 8.2. Matching 6.8nH matching circuit.
