Introduction

The SGW2828-EVK is a evaluation kit (Figure 1) designed for the development and Proof-of-concept testing of applications based on the SGW2828-01A LoRa Module. With the associated PC software, testing is easily enabled when two or more users are connected and using the same frequency channel. The PC software is supported by Windows operating systems (Windows 10).

Required Tools

The SGW2828 Module’s long-range and wall-penetrating capabilities are best demonstrated when testing is conducted with at least two individual users. Each user should be equipped with the following:
a. SGW2828-EVK LoRa Evaluation Kit
b. +2dBm SMA antenna
c. Micro-USB cable
d. PC with Windows 10 or above
e. SGW2828-EVK PC Tool program

Operation Guide

a. Preparation

1. Download the SGW2828-EVK PC software file at https://www.sgwireless.com/uploads/prod-uct/files/SGW2828%20PC%20Tools%20V1.5.1.zip. Extract the file for the SGW2828-PC-Tool program.
2. Prepare the SGW2828-EVK by screwing on the antenna, then connect the SGW2828-EVK to the PC with the micro USB cable (Figure 2). Toggle the power switch to ON.
3. Run the SGW2828-PC-Tool program.

b. Configuration of PC Software

1. Select the COM port number assigned for the connected SGW2828-EVK, then click ‘Connect’. The COM port number may be different for each user, and can be found through Device Manager > Ports (COM & LPT) (Figure 3).
   Remarks: If the desired COM port number is not showing in the drop-down menu, click ‘Refresh’.

2. Configure the RF Parameter, if needed. Users can use the default parameter settings or configure theirown at Menu > Configuration > RF Parameter (Figure 4). Data transmission is enabled when users use the same parameter settings.
   • ‘Read’: Read current parameter settings of connected SGW2828-EVK
   • ‘Write’: Save customized settings
   • ‘Fast Rate’/’Normal’/’Long Range’: Use pre-configured settings
   • ‘Default’: Reset to default settings

Table 1: Preset Parameters

---|---|---|---|---
Preamble| 16| 16| 16| 16
Bandwidth| 500kHz| 250kHz| 125kHz| 250kHz
Code Rate| 1| 1| 4| 1
SF| 7| 9| 12| 7
Hop Period| 0| 0| 0| 0
Channel| 0| 0| 0| 0
TxPow| -4dB| 4dB| 4dB| 4dB

c. User Application Mode
User Application mode enables several tests for the SGW2828-EVK capabilities and proof-on-concept development:
i. LED ON/OFF
ii. Text
The PC Tool is set to User Application mode by default, and can be accessed in
Engineering mode by Menu > Mode > Application Mode (Figure 5).

i. LED ON/OFF (Figure 6)
Click ‘LED2’ and ‘LED3’ to toggle the LEDs on or off on remote users’ SGW2828-EVK. Messages will show up in the message boxes of both local and remote users’ PC Tool.

ii. Text (Figure 7)
Input messages in the message box and click ‘Send’. Messages will show up in the message boxes of both local and remote users’ PC Tool.

d. Engineering Mode
Engineering mode is designed for AT command testing, for example:
i. Get firmware version
ii. Send text thru AT command
The PC Tool is set to User Application mode by default, and Engineering mode can be accessed by Menu > Mode > Engineering Mode (Figure 8).

Remarks: Please refer to AT Command Application Note for complete AT command list.
i. Get Firmware Version (Figure 9)
Type command AT+VERSION=? In the command input box and click ‘Send’. The firmware name and version number will be shown in message box.

ii. Send Text Thru AT Command
Type AT+RF_SEND=1,0,4 in command input box and type text (e.g. abcd) in the message input box and click ‘Send’ (Figure 11). Tick the Hex box if the message is in Hex format data.
Remarks: Please refer to AT Command Application Note for complete AT command list.

On the local PC Tool, the sent message will be shown in Hex format in the message box on the left, while details of data received and sent will be shown in the message box to the right (Figure 11).

On the remote PC Tool, the received message will be shown in the message box to the left, with details in the message box to the right (Figure 12). Hexidecimal values will only be shown in the message box to the right.

e. Firmware Upgrade
When available, firmware updates can be made at Menu > Others > Firmware Upgrade (Figure 13).

Click ‘FileDir’ to select the firmware file, then click ‘Upload’ to start the upgrade. A progress bar will appear – please stay on the page until the upgrade procedure is complete (Figure 14).
After firmware upgrade is completed, click the Arrow to return to the main page. Then check the firmware version in Engineering Mode by command AT+VERSION=? to ensure upgrade is completed.
