It supports a network stack along with SSL security, enabling full-featured internet connectivity and reliable information exchange in a small, low-cost system. The LTM1215 module contains a Midea WIFI IOT SIP LTP1218. The LTP1218 is a single chip system on a chip (SoC) 1x1 802.11 b/g/n device optimized for low-power embedded applications with single-stream capability for both Tx and Rx. It has an integrated network processor with a large set of TCP/IP with IPv4/IPv6-based services. The LTM1215 provides UART_based host interfaces for connecting to local system controllers. 1.2 Hardware Description Size: 18 x 13 x 3.8 mm Tolerance：±0.3mm Operating voltage: 3.6 V ~5.5V Operating humidity: 20-70% Operating temperature range: o Industrial: -40°C ~ +85°C o Commercial: -10°C ~ +65°C Power consumption o Transmit: 250 mA @16dBm o Receive: 75 mA (typical) o Power saving mode(DITM=1): 1.09mA o Standby mode(Sleep): 130uA Connector: DIP or SMD-Pad connector - 4 Pads Host interface: UART o UART interface: Supports AT style command set. 1.3 Wireless Specification Standard supported: IEEE802.11b/g/n Frequency: 2.412 to 2.484GHz Channels: up to 13 channels -5- LTM1215 Datasheet V1.1 1.4 Performance Specification Host data rates o UART: 115200bps, 8, n, 1 Link rates o Up to 150MHz 1.5 Protocols Internet protocols: IPv4/IPv6, TCP/UDP, ARP/NDP, DHCPv4, ICMPv6 Security protocols: WPS, WPA, WPA2, WAPI, WEP, TKIP 1.6 Typical application ● Household appliances ● Gaming consoles ● Handheld terminals ● Embedded wireless products ● security monitoring device ● industrial remote control ● Home automation 1.7 Warranty One Year 1.8 Certifications CE FCC ROHS compliant -6- LTM1215 Datasheet V1.1 2.System Block Diagram 2.1 Module System Block Diagram Power DC-DC LTP1218 UART Level Shift 2.2 Typical design AC Input User MCU 8bit or 32bit AC To DC UART DC-DC/LDO 300mA/3.3V LTM1215 Keyboard Display Action Sensor DC -7- LTM1215 Datasheet V1.1 3.Features 3.1 IPv4/IPv6 Networking The QCA4004 includes a TCP/IP and UDP offload capability. This capability can reduce Flash requirements on a host MCU by up to 100 KBytes and also free up CPU cycles. The IP stack is a simultaneous IPv4/IPv6 stack with a BSD-like interface to simplify porting and integration with common embedded operating systems. The supported features of the QCA4004 (support for DHCP, multicast, and ARP) include: ● ARP ● Forwarding ● Fragmentation/reassembly (supported with limitation) ● IPv4/v6 header processing ● UDP/TCP socket support ● DHCP v4 ● Neighbor discovery ● Broadcast/multicast ● Path MTU discovery ● Address auto-configuration ● Multicast ● TCP zero-copy feature QCA4004 IPv4 Supported RFCs IPv4 RFC Number RFC 1122 (TCP Timeout/retransmission) RFC1122:TCP Keep-alive RFC1122:TCP Zero-Window-Probe RFC1122:TCP Sliding window protocol -8- LTM1215 Datasheet V1.1 QCA4004 IPv6 Supported RFCs IPv6 RFC Number RFC-2464:Transmission of IPv6 packets over Ethernet networks RFC-2460:Internet Protocol version 6 RFC2462, Duplicate Address Detection (DAD) RFC-2463:ICMPv6 RFC3513:IP version 6 addressing architecture RFC3484:Default Address Selection RFC2461:Neighbour discovery for IPv6 host RFC4862:Stateless Address Auto-configuration 3.2 Power Management LTM1215 provides integrated power management and control functions for maximum battery life across all operational states. Transmit: 250 mA @16dBm; Receive: 75 mA (typical) Power saving mode: 1.09 mA(DTIM=1) Standby mode(Sleep): 130uA Sleep state minimizes power consumption while network services are not required, yet the system needs to remain available for use within a short time. -9- LTM1215 Datasheet V1.1 State SLEEP Typical Current Consumption for LTM1215 module 130uA DTIM1 1,090uA 802.11g DTIM3 437uA (2.4GHz) DTIM5 335uA DTIM10 274uA 3.3 Application Program Interface APIs provided by Qualcomm enable flexible host application customization. The firmware is written, owned, controlled, and maintained by Qualcomm , whereas the reference host software is supplied for system integrator to create application-specific host software, or even to use without modification. Note: If system integrator leverages the Qualcomm host software components, ultimately the system developer is responsible for the host software on their platforms, OSes, and interconnects. 3.4 WiFi Link Feature IEEE 802.11b/g/n, single stream 1x1 Single-band 2.4 GHz Integrated PA, LNA, with support for external PA and external LNA Green Tx power saving mode Low power listen mode Two-layer PCB design Link rates up to 150 Mbps - 10 - LTM1215 Datasheet V1.1 4.LTM1215 Pin-out 4.1 Pin-out Top view 4.2 LTM1215 Pin Assignment and Descriptions PIN Signal Name Description VCC Supply Input Pin RXD UART receive data TXD UART transmit data VSS Ground 5,6 VSS Ground for SMT - 11 - LTM1215 Datasheet V1.1 5.Electrical Specifications 5.1 Absolute Maximum Ratings Table 5-1 summarizes the absolute maximum ratings and Table 5-2 lists the recommended operating conditions for the LTM1215.

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: This equipment has been tested and found to comply with the limits for a Class B digital device, to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residentialinstallation. 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 cause harmful 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. FCC Caution: Any changes or modifications not expressly approved by the partyresponsible for compliance could void the user's authority to operate this equipment. This transmitter must not be co-located or operating in conjunction with any otherantenna or transmitter. Radiation Exposure Statement: This equipment complies with FCC radiation exposure limits set forth for anuncontrolled environment. This equipment should be installed and operated withminimum distance 20cm between the radiator & your body. This device is intended only for OEM integrators under the following conditions: 1) The antenna must be installed such that 20 cm is maintained between the antennaand users, and 2) The transmitter module may not be co-located with any other transmitter or antenna. As long as 2 conditions above are met, further transmitter test will not be required. However, the OEM integrator is still responsible for testing their end-product for anyadditional compliance requirements required with this module installed IMPORTANT NOTE:In the event that these conditions can not be met (for examplecertain laptop configurations or co-location with another transmitter), then the FCCauthorization is no longer considered valid and the FCC ID can not be used on thefinal product. In these circumstances, the OEM integrator will be responsible for reevaluating the end product(including the transmitter) and obtaining a separate FCCauthorization. End Product Labeling This transmitter module is authorized only for use in device where the antenna may be installed such that 20 cm may be maintained between the antenna and users. The final end product must be labeled in a visible area with the following: “Contains FCC ID: 2AIRV0001”. The grantee's FCC ID can be used only when all FCC compliance requirements are met. Manual Information To the End User The OEM integrator has to be aware not to provide information to the end userregarding how to install or remove this RF module in the user’s manual of the endproduct which integrates this module. The end user manual shall include all required regulatory information/warning as show in this manual.
