Parsing data according to the BLE data type, see the detail section. BLE broadcast data has a certain format: length + type + content The broadcast content can be changed, while data type is fixed, and the length is determined by the content. The device has two broadcast formats, transparent broadcast packets and iBeacon broadcast packets. Both formats contain four types: flag (0x01), broadcast name (0x09), service data (0x16), manufacturer data (0xFF). The following figure shows the transparent transmission of the broadcast packet: flag, broadcast name, service data is placed in the broadcast data packet, and manufacturer data is placed in the reply data packet. The content of service data is: service data UUID (E1FF) + MAC address. The content of manufacturer data consists of company id (3906) + battery level information (1 byte) + custom data. NoteThe IOS system cannot obtain the contents of the MAC address field, so the MAC address is put into the broadcast packet again to ensure that the IOS system can obtain the MAC address of the device. www.minew.com Minew@minew.com

If you need to save the modified content after power-off, you need to send a reset command to take it into effect. Note When you need to modify multiple parameters, you can send all the setting commands first, and then send the reset command. When querying the device parameters, it is shown with hexadecimal numbers. When choose to display by ASCII format, the parameter position may be garbled.

Violators will be held accountable in accordance with the law. Copyright Shenzhen Minew Co., Ltd. MS52SF1 Specification V1.0 10.1 Design notes It is critical to following the recommendations of this document to ensure the module meets the specifications. The module should be placed at the edge of the circuit board as far as possible to keep away from other circuits. Antenna should be kept away from other circuits. It can prevent low radiation efficiency and the normal use of other circuits from being affected. The landing of components should be appropriate and that is better for reducing the parasitic inductance. Please refuse to supply voltage that is not within the range of specification. Please make sure the module or its surface may not suffer from the physical shock or extreme stress. 10.2 Layout note To make sure wireless performance is at its best condition, please layout the MS45SF1 module on the carrier board as below instructions and picture. a) Placement of the antenna The antenna area of module shall lay clearance completely and should not be blocked by the metal. Otherwise it will have effect on antenna performance (As the picture indicated below). b) Placement of top-layer The placement of top-layer in carrier board shall be lay copper completely to reduce the signal line in carrier board or other interference. c) Clearance The upper and below area of antenna (including the case) shall have 4mm or more than 4mm clearance to reduce the influences for antenna 10.3 Installation and soldering Please do not lay copper under the module antenna. It can prevent the influence of signal radiation and the transmission distance from being affected. www.minew.com Minew@minew.com

Violators will be held accountable in accordance with the law. Copyright Shenzhen Minew Co., Ltd. MS52SF1 Specification V1.0 10.4 Handling and storage a) Due to the fact that CMOS components are included in the module, it is better to eliminate static electricity at any methods when transporting or working with the module. Moreover, it is strongly recommended adding anti-ESD components to circuit design to hinder damage from real-life ESD events. Anti-ESD methods can be also used in mechanical design. b) Please store the modules within -40 to +125 before and after installation and make sure the modules is away from the direct sunlight exposure for a long duration. Modules should be far away from humid and salty air conditions, and any corrosive gasses or substances. c) Please not to wash the module. No-Clean Paste is used in production. The metal shield may be oxidized by the washing process and may lead to chemistry reaction with No-Clean Paste. If modules goes through the washing process, functions of the module may not guaranteed. d) After opening the package, it should be stored in vacuum environment. Module should not be exposed to the air for a long time to prevent moisture and pad oxidation. If there is an in terval of 7 to 30 days during SMT process. 10.5 Life support applications a) The module is not design for life support device or system and not allowed to be used in destructive devices or system in any direct, or indirect ways. Minew is not responsible for compensation of any losses when applying modules under such application as described above. b) Minew shall not responsible for the customers products or application. www.minew.com Minew@minew.com
