The SX1301 will be controlled and configured by ST Nucleo-F746ZG board via SPI. In this module, the external PA is removed refer to Semtech’s reference design. The maximum output power will decrease to be about 6dBm for downlink. To get a wider operation bandwidth for evaluation, two parallel SAWs will be used instead of the single band SAW. Two RF switches are used to select the target band which would be used in the application. And the band selection is done automatically by software with frequency channel identification. Users no need to set it by manual.

When it is done, the firmware is programmed successfully. 4.3 Get Started 1. Set up the system and connect the hardware like Figure 4-1. 2. Program the GW with the right binary file with right frequency plan and right cloud server. Skip this step if the default configuration is acceptable for you. 3. Check Log with extraputty or some similar tools. Power up the system and reset the Nucleo board. The log with some useful information will be shown on window of the extraputty. Configuration is “115200, 8, n, 1”. Figure 4-2 log shown after reset Nucleo board Some useful information needs to be known from this log, MAC Address, predefined channels and server address. All these configurations are configurable by user through AT command.
V2.7 2017-09-28 www.risinghf.com ST Nucleo LoRa GW User Guide RisingHF 8 4. Register the GW to Loriot server with right MAC address. You need register an account first on the server before adding the GW. Please refer to step below for the details. For example, the MAC address is “08:00:27:xx:xx:xx”. Use below procedure to register gateway: (1) Log in to http://ap1.loriot.io server. If you want to connect to other server of Loriot, please change the server address. (2) Dashboard -> Gateway -> Add Gateway (3) Choose “Semtech Packet Forwarder” (4) Fill in the MAC address “08:00:27:xx:xx:xx” (5) Fill in the gateway location (6) Finish registration 5. Reset the GW. The ST Nucleo LoRa GW would connect to the server now. 4.4 Register Sensor Mote Due to this document date, Loriot packet forwarder mode could support all the function, like uplink and downlink, ABP and OTAA mode, Class A and Class C LoRaWAN and so on. Step below is an example to show how to register a device in ABP mode. 1. Dashboard -> Application -> SampleApp -> Manage devices. 2. Import Existing ABP 3. Fill in all necessary information includes DEVADDR, DEVEUI, APPSKEY, NWKSKEY, FCntUp, FCntDown. Note: If you don’t want that your device follow the strict sequence number checking rule, you could choose relaxed one to neglect it. Figure 4-3 Change seqno checking to be relaxed if need 4.5 Cautions For US915 frequency band, only US1 server of Loriot can support, for customers who need use US915 frequency band, please switch to us1.loriot.io. us1.loriot.io -915.bin firmware enables US915 Hybrid mode, CH0~7 are selected as the communication channels. Once your gateway is registered, please switch frequency plan to US915_CH0_7.

Channel 0 to 7 are Multiple Spread Factor channels, bandwidth of which are fixed 125KHz, channel 8 is standard LoRa channels which could supports 125KHz, 250KHz and 500KHz bandwidth, channel 9 is FSK channel 50Kbps (RXBW 125KHz ). Channel Radio Type Bandwidth Data Rate 0-10 A/B LoRa Standard 500KHz SF7 ~ SF12 (optional) The ST Nucleo LoRa GW integrates two radio frequency front end. Which is identified as radio A and B, the all 10 channels could be freely configured to use either of the two radios (A/B). Each of the Radio could cover maximum 1.1MHz (500KHz) analyze bandwidth, so when set new channels, please arrange the channels to radio carefully, so that bandwidth of radio is less than 1.1MHz. According to lora_gateway library v4.1.1, SX125x bandwidth limitation is described as below table: 5.6.16.2 Predefined Channel Plan Use “AT+CH=band” command to set predefined channel.

V2.7 2017-09-28 www.risinghf.com ST Nucleo LoRa GW User Guide RisingHF 21 7 Others information for reference 7.1 Power supply and consumption 7.1.1 Power supply The power supply +5V will be injected into the system via micro USB connector of the Nucleo shield (blue board) from an external adapter. The max rated current of this adapter is suggested to be more than 1A. The Nucleo board (white board) should be powered by the supply from the shield board. So the Nucleo board (white board) would be power supplied by VIN (Pin15 of CN8 on the Nucleo F7 board). Figure 7-1 Side View of the Nucleo LoRa GW Demo When STM32 Nucleo-144 board is power supplied by VIN, the jumper configuration must be the following: ⚫ Jumper JP3 on pin 5 and pin 6 for VIN ⚫ Jumper JP1 OFF Antenna Virtual COM External Power supply +5V
V2.7 2017-09-28 www.risinghf.com ST Nucleo LoRa GW User Guide RisingHF 22 7.1.2 Power consumption Table 7-1 below shows the current consumption of the Nucleo shield module in different mode. The maximum current would be almost 360mA when both uplink and downlink are on. Table 7-1 Power consumption of ST LoRa Nucleo GW Module Band Standby consumption Current @TX max OP Consumption @8 CH RX Only RX/TX ON Max Current HF 39mA 175mA 330mA 364mA For the consumption of the Nucleo F746ZG board, please refer to the manual from ST. The max current of this board would be more than 200mA depend on the source code and peripheral interface used. 7.2 LED status On the GW shield (Blue board), there is only one LED to show power supply. ➢ 5V_ON (Green): When there is external power supply +5V to the system from adapter, this LED will be ON. On the Nucleo F746ZG board (White board), there will be 3 LEDs will be used in the demo: ➢ LD3 (Red): ON -> ST LoRa GW board is detected, OFF -> ST LoRa GW board is removed ➢ LD2 (Blue): Blink when Packet is received ➢ LD1 (Green): Reserved For others LEDs used on the Nucleo F746ZG board, please refer to the manual of the Nucleo board from ST.

Please note that, there is no external PA refer to Semtech’s reference design, so the RF power is output from SX125x FEM directly. The maximum output power normally would be 6-7dBm type in different band. Table 7-2 RF performance Band Frequency TX op max/dBm Harmonic/dBm Sensitivity/dBm HF 915MHz 6dBm type Below -56dBm SF12 125kHz -140dBm SF11 125kHz -137dBm SF10 125kHz -134dBm SF9 125kHz -131dBm SF8 125kHz -128dBm SF7 125kHz -124dBm

V2.7 2017-09-28 www.risinghf.com ST Nucleo LoRa GW User Guide RisingHF 25 Revision V1.0 2016-06-22 + First version 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. (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, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. 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 NOTE: The manufacturer is not responsible for any radio or TV interference caused by unauthorized modifications to this equipment. Such modifications could void the user’s authority to operate the equipment. This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This radio transmitter [8976A-GSHF1] has been approved by Innovation, Science and Economic Development Canada to operate with the antenna types listed below, with the maximum permissible gain indicated.
