HARDWARE INFORMATION
EVALUATION BOARD
To facilitate the nal product’s developers, Ethertronics has built completed passive and active evaluation boards (EVBs) for ETH-LORA-M-AX-01 (V1.2). In order
to test the functionalities of the IM algorithm, a passive evaluation board is used and to test the functionalities of the MCD algorithm, an active evaluation board
is used. This evaluation boards come with test connectors to communicate with ETH-LORA-M-AX-01 using AT commands via UART interface.
PASSIVE EVALUATION BOARD
This passive evaluation is also provided with Ethertronics’ PresttaTM 1002232 Multi-Band ISM antenna which covers all the ISM frequencies
(868/915/2400 MHz).

USB UART CABLE
The communication between the host and the module is done using UART interface and AT Commands. To send the data to ETH-LORA-M-AX-01 module, the
USB to TTL serial UART converter cable with virtual COM port driver is necessary. FTDI TTL-232RG-VSW3V3-WE or TTL-232RG-VREG3V3-WE is recommended
for this purpose. The datasheet of this product can be found the FTDI website.

FTDI USB TTL UART CABLES
Since this cable is wire ended, user needs to make the connectors to connect with the EtherLoRa module pins.

COMPUTER WITH WINDOWS OS
The software tool is developed to be used on the computer that runs on windows operating system. To communicate with module using other operating
system, user can use serial port terminal.
CONNECTION
The connection of the four pins between the FTDI USB-UART cable and the EtherLoRa module is as below:
USB-UART CABLE AND ETHERLORA CONNECTION
There are two options to supply the voltage to the module on the EVBs. If the user wishes to use the battery to power the device, the voltage supply wire on the
FTDI UART cable does not have to be cabled. However user must set the toggle switch on the EVBs correctly.

SOFTWARE INFORMATION
Two software products are needed for to communicate with module on the evaluation board. The rst one is the VCP driver for USB-UART Cable. This document
won’t discuss the VCP driver in details. The VCP driver can be found on FTDI website as well as the instruction to install it.
Link: http://www.ftdichip.com/Drivers/VCP.htm, VCP Driver for FTDI USB-UART Cable
The second software is the ETH-LORA-M-AX-01 control tool. User can download EtherLoRa Control Tool installer from Ethertronics website or contact the
developers from Ethertronics.
Link: www.avx.com/products/modules/lora-module, ETH-LORA-M-AX-01 Control Tool’s Installer download
Other software that can be used to communicate with the module on the evaluation board is a terminal that can support serial port communication. For
example the open source terminal likes Tera Term. However the installation of the Tera Term won’t be covered in this document.
INSTALLATION
INSTALLING THE DRIVER
Before cabling the FTDI UART cable with the evaluation board, user must install the driver rst.
Download the VCP Driver of the FTDI USB-UART cable from the FTDI website or contact Ethertronics personal.
Install the driver.
Connect the FTDI USB-UART Cable and the EtherLoRa module. See details in Section 2.4 Connection.

ETHERTRONICS CONTROL TOOL
After launch the tool, the COM Port selection window is displayed. The default parameters on this window are correct, user does not need to change the serial
port parameters. User only needs to select the correct COM port from the combo box.
COM PORT SELECTION WINDOW
Once the button Set COM Port is clicked, the control tool will communicate with the ETH-LORA-M-AX-01 module to get the information about the module.
This will take up couples of seconds and the status will be displayed. If everything is OK, the main application form will be displayed. Otherwise the error will
be displayed.
WELCOME TAB
This welcome tab shows the name of the tool and as well as the version of the tool.

CONFIGURATION TAB
In this tab, user can verify the information about the detected module. Make sure that the Serial number is corresponding to the one written on the label on
top of the module. If there is any problem about the information of the module, user is advised to reset the module using the reset button (red push button on
the evaluation board) and click the check com port button to update the information or relaunch the tool. The plots control panel is used when the demo is
launched.
AUTO DEMO TAB
This tab is used to launch the demo of the algorithms in order to evaluate their performance. To use this tab user must have a LoRa gateway at disposition.
Otherwise the demo cannot be launch.
When the button Start Demo is clicked, if the module is not yet joined the network, the join procedure will be initiated. The join procedures will take up to ~45s.
The status of the current process will be displayed inside the status text box. If the selected demo type is not supported by the module, a message box will
be displayed. The MCD algorithm can only be evaluated on the active EVB. Once demo is correctly started, user can change to plots tab to see the plot of link
quality and information.

MANUAL DEMO TAB
Like the previous tab, this tab is used to launch the demo of the algorithms in order to evaluate their performance. In this tab, user must set all the parameters
of the algorithms, and launch them manually before starting to join the LoRa Network. After sending the message, user can start the data ow to evaluate the
algorithms. To use this tab user must have a LoRa gateway at disposition. Otherwise the demo cannot be launch.
In this tab, user has the liberty to change the default parameters of the algorithms before start the data ow. Once the parameters are set, user need to perform
the join procedure. If the join is successful, user can start the loop of sending message. In order to start the data ow, the number of iterations of the sending
message loop must be at least 15. If user wishes to send the message continuously, please set the number of iteration to “-1”. Then, user can start the data
ow. Once demo is correctly started, user can change to plots tab to see the plot of link quality and information.
LINK QUALITY TAB
This tab is only for display purpose. When the demo is correctly launched, user can see the display of the RSSI/SNR, radiation patterns and the algorithms’
result. To modify the axes of the plot, please go to Conguration Tab and adjust the values inside the Plots Control panel.
If the demo is not launched, these plots will not be displayed.

This tab is only for display purpose. When the demo is correctly launched, user can see the display of the RSSI/SNR, spreading factor and the frequency. To
modify the axes of the plot, please go to Conguration Tab and adjust the values inside the Plots Control panel.
If the demo is not launched, these plots will not be displayed.
LORA NETWORK TAB
This tab is used to modify the LoRa parameter of the modules. Once the button Set or Get is click, user need to wait until the status of the current operation is
displayed inside status text box.
If user modies these parameters and wishes to save them even after the module reboots, user can store the new values inside the EEPROM of the module
using the button Save.

This tab is used to send AT command directly to the module. User can type the AT command inside the text box and use the Key Enter to send the command
to the module. The answer will be displayed.
TERA TERM
An alternative tool to communicate with ETH-LORA-M-AX-01 is a serial port terminal. A free terminal like Tera Term can be used. Once the connection is done,
user can run the Tera Term application and the connection windows will be displayed automatically. Otherwise, user can open manually the new connection:
