Generate a Random number between 0 and 50 Use this number as a pointer to the hop table to generate random Transmit Frequency setting. Transmit at this frequency. RF micro generates an interrupt after every 4 hops to change frequency using the hop table Transmit frequency hopping algorithm Call rand() to generate the next random number. Transmit at this frequency. Exit No Random Frequency Generation Random frequency generation is accomplished by generating a uniformly distributed random number between 0 and 50 using this as a pointer to the hop table. The hop table consists of 50 channels frequency pairs uniformly distributed across the ISM band and are spaced approximately 50 KHz apart. The random number generation is accomplished using the function rand () available in the C library. The function generates a random number between 0 and 32768; this is divided by 654.9 to generate a random number between 0 and 50. The receive-side frequency generation has to be synchronous with the transmit-side frequency generation. This is accomplished by generating random numbers with the same seed in the transmit and receive side firmware routines. The hop table is stored in the header file hop.h in the firmware. Every 5 minutes from powering up the device it transmits it’s payload to the receiver. The pre-amble detect sequence is initiated on the channel 0. The hopping sequence commences when the receive detects the pre-amble on channel 0. the payload is then sent over a random channel sequence defined below. Use this number as a pointer to the hop table to generate random Transmit Frequency setting. Packet Sent? Yes Receive frequency hopping algorithm The receiver Hops to the same frequencies in the same random order as the transmitter. This is accomplished by calling the rand () function with the same seed in both transmit and receive routines. The receiver changes frequency once a Pre-amble is detected . The time between each hop is the same on both transmit and receive as they are both using the same delay routine and same device platform.

MODULAR APPROVAL REQUEST Date 05/06/2014 TRaC Global 100 Frobisher Business Park Leigh Sinton Road Malvern Worcestershire WR14 1BX UK RE: FCC Modular Approval FCC ID: ZWZ-ISL067 To Whom It May Concern: Please be advised that the manufacturer requests that the above-referenced model be approved for Licensed Modular Approval in accordance with the FCC Rules and Regulations. Our Product meets the FCC meet the FCC modular approval policies in the following ways: i The radio elements must have the radio frequency circuitry shielded. Physical/discrete and tuning capacitors may be located external to the shield, but must be on the module assembly; The radio frequency circuit is shielded by a CAN over the radio circuit ii The module must have buffered modulation/data inputs to ensure that the device will comply with Part 15 requirements with any type of input signal; The RF chip has buffers on in- and out-puts. If the RF-chip is decoupled properly on its power supply pins, the risk of having interference between the digital parts and the analog RF are kept to a minimum. iii The module must contain power supply regulation on the module; The power supply regulator is affixed to the module. iv The module must contain a permanently attached antenna, or contain a unique antenna connector, and be marketed and operated only with specific antenna(s), per Sections 15.203, 15.204(b), 15.204(c), 15.212(a), 2.929(b); The module has unique antenna connector which is UFL to RP SMA Male v The module must demonstrate compliance in a stand-alone configuration; The module has been fully testes to meet this requirement.

The grantee must provide comprehensive instructions to explain compliance requirements; viii The module must comply with RF exposure requirements. For any transmitters intended for use in portable devices, SAR compliance must be demonstrated to be independent of the host device. See KDB Publication 447498 Item 2) as a guide to determine if a transmitter can be tested without being limited to a host device. If SAR compliance can only be demonstrated in specific host types or platforms, then the module type must be “limited.” Thank you for your attention to this matter.

Using Semtech’s patented LoRa TM modulation technique SX1276/77/78 can achieve a sensitivity of over -148dBm using a low cost crystal and bill of materials. The high sensitivity combined with the integrated +20 dBm power amplifier yields industry leading link budget making it optimal for any application requiring range or robustness. LoRa TM also provides significant advantages in both blocking and selectivity over conventional modulation techniques, solving the traditional design compromise between range, interference immunity and energy consumption. These devices also support high performance (G)FSK modes for systems including WMBus, IEEE802.15.4g. The SX1276/77/78 deliver exceptional phase noise, selectivity, receiver linearity and IIP3 for significantly lower current consumption than competing devices. QFN 28 Package - Operating Range [-40;+85°C] Pb-free, Halogen free, RoHS/WEEE compliant product LoRa TM Modem 168 dB maximum link budget +20 dBm - 100 mW constant RF output vs. V supply +14 dBm high efficiency PA Programmable bit rate up to 300 kbps High sensitivity: down to -148 dBm Bullet-proof front end: IIP3 = -11 dBm Excellent blocking immunity Low RX current of 9.9 mA, 200 nA register retention Fully integrated synthesizer with a resolution of 61 Hz FSK, GFSK, MSK, GMSK, LoRa TM and OOK modulation Built-in bit synchronizer for clock recovery Preamble detection 127 dB Dynamic Range RSSI Automatic RF Sense and CAD with ultra-fast AFC Packet engine up to 256 bytes with CRC Built-in temperature sensor and low battery indicator Automated Meter Reading. Home and Building Automation. Wireless Alarm and Security Systems. Industrial Monitoring and Control Long range Irrigation Systems GENERAL DESCRIPTION ORDERING INFORMATION Part NumberDeliveryMOQ / Multiple SX1276IMLTRTT&R3000 pieces SX1277IMLTRTT&R3000 pieces SX1278IMLTRTT&R3000 pieces KEY PRODUCT FEATURES APPLICATIONS www.semtech.comPage 2 SectionPage Table of contents SX1276/77/78 WIRELESS & SENSING DATASHEET Rev. 1 - September 2013 ©2013 Semtech Corporation 1.
