1 OVERVIEW AND KEY FEATURES
The BTM410 and BTM411 Bluetooth® modules from Laird are designed to meet the needs of developers who wish to add robust, short range Bluetooth data connectivity to their products. These modules are based on the market leading Cambridge Silicon Radio BC04 chipset, providing exceptionally low power consumption with outstanding range. They support the Bluetooth® version 2.1 specification, providing the important advantage of Secure Simple Pairing (SSP), which improves security and ease of use for end customers. With physical sizes as small as 12.5 mm x 18.0 mm and best of class, low-power operation, these modules are the ideal choice for applications where designers need both performance and minimum size. For maximum flexibility in systems integration, the modules are designed to support a separate power supply for I/O. To aid product development and integration, Laird has integrated a complete Bluetooth protocol stack within the modules, including support for the Bluetooth Serial Port Profile. The modules are fully qualified as Bluetooth End Products, allowing designers to integrate them within their own products with no further Bluetooth Qualification. They can then list and promote products on the Bluetooth website free of charge. A comprehensive AT command interface is included, which simplifies firmware integration. Combined with a low cost developer’s kit, choosing Laird Bluetooth modules guarantees the fastest route to market. Features and Benefits Bluetooth® v2.1+EDR Adaptive Frequency Hopping to handle interference from other wireless devices Secure Simple Pairing (SSP) support External or internal antenna options Comprehensive AT interface for simple programming Bluetooth® End Product Qualified Compact size Class 2 output – 4 dBm Low power operation UART interface PCM and SCO for external codec GPIO lines under AT control Wi-Fi co-existence

3 FCC REGULATORY STATEMENTS
3.1 BTM410 FCC and Industry Canada Statements
The Final Equipment user manual must show the following statements: 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 devi ce must accept any interference received, including interference that may cause undesired operation. Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. To comply with the FCC RF exposure compliance requirements, this device and its antenna must not be co-located or operating to conjunction with any other antenna or transmitter.
3.1.1 Considerations for OEM Integration
This module has a limited modular approval. Approval with any other antenna configuration or layout other than that approved will necessitate additional radiated emission testing to be performed. To inherit the modular approval, the antennas for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter. This module was approved with the following antenna: RF Solutions: ANT-24G-WHJ-SMA 0dBi Operation of this module with any other antenna will require additional testing to be performed. Co-location with other radio transmitting devices operating concurrently in the same band will require additional testing and certification. Designers should note the distinction that the FCC makes regarding portable and mobile devices. Mobile devices are defined as products that are not used closer than 20cm to the human body, whereas portable devices can be used closer that 20cm to the body. A device may be used in portable exposure conditions with no restrictions on host platforms when the averaged output power is less than the low power threshold for an uncontrolled environment ≤ 60/f(GHz) i.e. 25mW for a 2.4Ghz device. The Maximum Power Exposure for the BTM410 has been evaluated and found to comply with the low power threshold for an uncontrolled environment. Refer to FCC document KDB 447498 for more information on RF exposure procedures and equipment authorization policies for mobile and portable devices.
3.1.2 FCC Labelling Requirement
If the FCC ID is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following: “Contains Transmitter Module FCC ID: PI4410B” or “Contains FCC ID: PI4410B.” Any similar wording that expresses the same meaning may be used.
