3.2.2 HW architecture of ST Nucleo LoRa GW Module
The Module is composed of one pcs of SX1301 and two pcs of SX125x FEM. 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.

4.1 Hardware connection
 Use a 5V 1A adapter to connect to the ST Nucleo LoRa GW Module on the top to power the
system
 Connect the micro USB connector CN1 of the Nucleo board on the bottom to PC with a USB cable.
This USB port could be used as FW download port or as Virtual COM port for message monitor or
log checking.

If you want to upgrade to a new firmware, please follow step below:
1) Connect ST Nucleo F746ZG to PC, then a mass storage device could be recognized.
2) Drag the target bin file and drop to the “NODE_F746ZG” device. 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.

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.
