1. Where is the latest firmware file?
If you want to get a pre-compiled firmware instead of compiling the source code by
yourself, you can find the latest firmware on RAK website after it is released.
2. How to burn the update firmware into
RAK7200?
Firstly, please install the “STM32CubeProgrammer” tool on your Windows PC. You
can download it from here:
https://www.st.com/content/st_com/en/products/development-tools/software-develop
ment-tools/stm32-software-development-tools/stm32-programmers/stm32cubeprog.h
tml#overview
Secondly, connect RAK7200 with your PC’s USB interface as follow:
Now, you need to let RAK7200 work in boot mode. You can do it as follow:
v2.0.0.0.0
4
1. Hold down the BOOT0 button, then press the Reset button;
2. Loosen the Reset button, then Loosen the BOOT0 button.
Open the “STM32CubeProgrammer” tool, and select UART type, then configure the
Port, Baudrate, and Pairty as the following picture shows:
Note: It is COM5 on my computer, and it may be another COM port on your computer.
Then press “Connect” button at the top right corner. If there are some errors in the Log
box as follow:
v2.0.0.0.0

It means that RAK7200 don’t work in BOOT mode. You should let it work in boot
mode firstly.
The correct Log you should see is the information like the following picture shows:
Now, let’s start to burn a firmware into RAK7200.
At first, erase all data on RAK7200 according the following picture shows, it may take
several seconds:
v2.0.0.0.0
6
Press “Open file” and select the correct firmware file in the pop-up window as follow:
v2.0.0.0.0
7
Press the “Download” button to start the burning process:
v2.0.0.0.0
8
OK, you have upgraded the firmware for RAK7200 successfully!
Now, “Disconnect” and close the “STM32CubeProgrammer” tool, then open a serial
port tool on your PC. Choose the correct COM port and baud rate is 115200. Then
press the Reset button on RAK7200, you’ll see the following log on serial port tool:
v2.0.0.0.0
9
Note: If you haven’t a serial port tool, we recommend you to use RAK serial port tool.
You can get it from RAK website and use it freely.

4. How to connect with TTN?
In this section, we’ll do some practice to show how to connect RAK7200 with TTN.
Firstly, open the serial port tool on your PC.
Open the serial port by click the following button:
v2.0.0.0.0
14
“add application”:
Fill in the correct contents.
Please note that the content you fill in “Application ID” item should be in low case, and
it must be the unique ID on TTN network.
Then press the “Add application” button at the bottom of this page, and you can see
the following page:
v2.0.0.0.0
15
At the middle of this page, you can find the box named “DEVICES”:
Just “register device”:
You can click the following icon and “Device EUI” will be generated automatically in
the next step:
v2.0.0.0.0
16
The following picture shows the final page:
Then press the “Register” button at the bottom of this page to finish.
v2.0.0.0.0
17
4.1 Join in OTAA mode
As you see in the above page, the default activation method is OTAA.
These three parameters will be used on RAK7200:
OK! Now, let’s join in OTAA mode and AU915 frequency for example!
The default LoRa work mode is LoRaWAN 1.0.2, the default LoRa join mode is OTAA,
and the default LoRa class is Class A.
Set the frequency/region to AU915:
v2.0.0.0.0
18
Set the Device EUI:
Set the Application EUI:
v2.0.0.0.0
19
Set the Application Key:
v2.0.0.0.0
20
Join in OTAA mode:
Join successfully! You can see that RAK7200 is sending data frequently.
Now, you can see the sensor data send from RAK7200 on TTN website as follow:
Great! That’s all about OTAA mode.
4.2 Join in ABP mode
