LoRa Mipot USB-DONGLE USER’S MANUAL
Code: 32001388
INTRODUCTION:
This USB-Dongle has been developed to test the functionality and radio parameters of the LoRa Mipot
transceiver 32001345.
The unit interfaces with the PC via USB port and can be configured using a GUI.
The USB-Dongle comes in two different hardware designs. The first with 868 MHz antenna integrated
on the printed circuit board and the second with the SMA connector.

➢Open the GUI by double clicking on the icon.
➢Select the COM port through “COM SELECTION” tab.
➢Set “BAUDRATE” to 115200 baud.
➢Click on “Open”button. The tabs on the window on the right side become active.
NOTE: to check if a device is connected, verify that each input command has an answer in
the blue box below.
In this example, AA3302000819 is the command that performs an EEPROM read of radio
parameters and then sends it through the serial COM port.
[AA] protocol header
[33] command id
[02] command lenght
[00] EEPROM start address
[08] number of bytes to be read
[18] checksum

Please refer to 32001345 LoRa module datasheet for more informations about commands,
radio parameters and electrical characteristics.
7. USB-Dongle MASTER Configuration
➢Make sure the USB-Dongle is set as MASTER in “Radio Config” page.
➢Set Power (dBm) to 14dBm in “Radio Config” page.
➢Set Frequency Band (MHz) in “Radio Config” page.
The USB-Dongle is now set as MASTER.
8. USB-Dongle END-NODE Configuration
➢Make sure a LoRa MASTER has been configured.
➢Set the USB-Dongle as END-NODE in “Radio Config” page.
➢Set Power (dBm) to 14dBm in “Radio Config” page.
➢Now the END-NODE is ready to be paired to the MASTER (see section below).
9. PAIRING PROCEDURE

Rev. 1.0

Page 6 of 10
➢Start one GUI application for the MASTER device and another for the END-NODE
device.
➢Start the pairing mode by clicking on the “Enable Pairing Mode” button in “Network
Config” page (MASTER GUI).
➢Click on the “Pairing Request” button on the “Network Config” page (END-NODE GUI).
➢Press the button “Get Activation Status”. If the END-NODE is correctly paired the state
box should change to “paired” (END-NODE GUI).
If the END-NODE device is correctly paired, the serial number of the master’s module
is displayed in the MST(HEX) indicator Box (END-NODE GUI).

➢To check the number of END-NODES devices paired to the MASTER Push “Get Table
Size” button (MASTER GUI).
If table size number is equal to 0it means that no slave device has been paired to the
master yet.
10. RADIO LINK TEST (ONLY FOR END-NODE DEVICES)
➢Make sure that the pairing procedure succedeed.
➢Set Power (dBm) to 14 dBm.
➢Set Msg Nb (message number) to 10.
➢Set Msg Th (message threshold) to 8.
➢Begin test by press the LINK CHECK Button and wait some seconds.
The “Result”box indicates the status of the test. If the number of received message is
greater or equal to <Msg Th> the result of the test is positive.
If the number of received message is less than <Msg Th> the result of the test is negative.
OK = TEST PASS
KO = TEST FAIL

My TEST LINK result is FAIL, what could I check?
Check the pairing state of END-NODE device in the “Network config page”. The state
should be “paired” and the number displayed in MST(HEX) should be the MASTER serial
number.
Check your message threshold value. Try with a message threshold (Msg Th) around
50%-60% of the total message number (Msg Nb).
Repeat MASTER and END-NODE pairing.
11. MESSAGE TRANSMISSION
A message transmission message is possible from MASTER to END-NODE and from END-
NODE to MASTER . It can be sent in Confirmed or Unconfirmed mode.
➢Complete the pairing procedure described in the previous pages.
➢Set 5 in the “Unconfirmed Tx Nb” box in Radio Config page.
This parameter indicates the number of times than a single unconfirmed message is
sent from the transmitting device.
➢Set 5 in the “Confirmed Retry Number” box in Radio Config page.
This value indicates the number of times than an confirmed message is sent if ACK is
not received.
➢Press ” WRITE” button to store the parameters into device.
➢Write the message in HEX format in the END-NODE table “DATA(HEX)”.
➢Send the confirmed or unconfirmed message by pushing selected buttons in the
END-NODE table. Message will be displayed in the master tab.
