Wisblock RAK19007 and RAK7240CV2 Gateway

CLehnen · April 5, 2025, 2:21am

I am trying to field test my RAK7240CV2 gateway to see if at different places throughout my field site it has connectivity either 1) via SIM card or 2) via line of site with another Ethernet connected RAK7240CV2 gateway

Ideally, it would be great to collect data on signal strength at different coordinates, however that is not necessary. The only thing necessary is to test if the the gateway internet connected, i.e. is able to send any sort of end node data to the cloud. I also would like a cheap option and need one that can be delivered quickly before I go into the field

I am still extremely new to this, but I was looking at the Wisblock RAK19007 kit because it is cheap and ships fast on Amazon. Would that work for my purposes?

Welcome back to the forum @CLehnen
We have two connectivity range tester and two examples for DIY tester:

1) FieldTester RAK10701

FieldTester RAK10701
RAK10701 Docs

Pros:

IP65 enclosure
Big RGB LCD touch screen
Lot of connection information provided
Supported by WisToolBox for setup

Cons:

Requires a back-end to send connection info back to the device
- RAKwireless WisGate with WisGateOS V2 and Fieldtester extension (Only Fieldtester Plus, coming soon)
- Cloud backup connected to TTN, Chirpstack or Helium. A few other LoRaWAN LNS are supported as well, see documentation

2) FieldTester RAK10706

FieldTester RAK10706
RAK10706 Docs

Pros:

Small and lightweight
Supports different test modes
- Fieldtester Mode: compatible with RAK10701-L)
- LinkCheckReq function: Works with any LoRaWAN server, no need for back-end installation
- LoRa P2P basic test function

Cons:

3D printed enclosure, not waterproof
Small OLED screen
UI control with a single button interface (less comfortable, compared with RAK10702 Fieldtester)
Not supported by WisToolBox for setup

3) DIY option 1:

Build a RAK10706 FieldTester with WisBlock RAK19026 Base Board.
Required components:

RAK19026 Base Board with OLED display and acceleration sensor. Requires bootloader change from Arduino to RUI3 to run open source RAK10706 firmware
RAK10706 Firmware

Pros:

Same functionality as RAK10706
Small and lightweight
Supports different test modes
- Fieldtester Mode: compatible with RAK10701-L)
- LinkCheckReq function: Works with any LoRaWAN server, no need for back-end installation
- LoRa P2P basic test function

Cons:

No enclosure provided
Small OLED screen
UI control with a single button interface (less comfortable, compared with RAK10702 Fieldtester)
Not supported by WisToolBox for setup

4) DIY option 2:

Build a Fieldtester with WisBlock modules. No UI to change settings without USB connection and serial terminal.
Required components:

Pros:

Similar functionality as RAK10706
Small and lightweight
Supports different test modes
- Fieldtester Mode: compatible with RAK10701-L)
- LinkCheckReq function: Works with any LoRaWAN server, no need for back-end installation
- LoRa P2P basic test function

Cons:

No enclosure provided
Small OLED screen
No parameter changes in the field. Requires USB connection and serial terminal for changes.
Not supported by WisToolBox for setup

Hello,

Thank you very much for this thorough answer! The RAK10706 looks perfect for my future testing and I will purchase it in the future to make things easier

However, in my current situation I only had limited time to order and receive the equipment I needed. These were the only items that arrived in time:

Base RAK19007
Core RAK4631
LoRa antenna
Bluetooth antenna
96 Inch OLED Display Module 128x64 LCD Screen Board SSD1315
3.7V 5000mAh Lithium Polymer Rechargeable Battery
RYS352A +3.3V UART GNSS interface

Although not the ideal equipment to make a DIY module like the list you provided, do you think it would be still possible to make a good-enough DIY tester from the equipment I have to test 1) internet connectivity of my RAK7240CV2 gateway using a SIM card and 2) if I remove the SIM card if my field deployed gateway can forward data to an Ethernet connected RAK7240CV2 gateway via line of sight?

If so, do you have any tips on how to accomplish this?

beegee · April 7, 2025, 1:53am

Yes, it can work, even without the GNSS module. The RAK10706 firmware I shared does not support a GNSS module with UART, it is written for the RAK12500 with I2C connection.
But for basic LinkCheckReq testing (without distances/location to gateway) it will work.

With a RAK10706 you will get in addition the distances/location of the tester and gateways and the option to write the test results to the SD card on the device.

For a quick test, you can assemble the RAK19007, RAK4631 and the display and flash the firmware.
But the RAK10706 firmware is for RUI3 based RAK4631’s, so you need to change the bootloader as shown in our Documentation Center => Updating RAK4631 to RUI3

Thank you very much! This was very helpful, I had been heading in the wrong direction unfruitfully for the past few hours. Your solution worked very smoothly

I got this far without an issue:

Create Folder & Download Files
Create a folder: C:\RAK4631 Bootloader to RUI v3.
Download & unzip these files into the folder:
- adafruit-nrfutil.exe
- rui3_nrf52840_bootloader
Connect RAK4631-R via USB
Check COM port via Device Manager (Windows + X > Device Manager > Ports).
If not detected, double-click the reset button on the WisBlock Base.
Bootloader Upgrade
Open Command Prompt as Administrator.
Navigate to the folder:

cd C:\RAK4631 Bootloader to RUI v3\

Run this command (replace <COM#> with your actual port number):

adafruit-nrfutil.exe --verbose dfu serial --package rui3_nrf52840_bootloader_latest.zip --port COM<COM#> -b 115200 --singlebank --touch 1200

After upgrade, note the new COM port number (e.g., COM31 to COM32).
Download Firmware Files
Download & place these files in the same folder:
- nrfutil.exe]
- rui3_rak4631_latest
Firmware Update
In Command Prompt (Administrator), navigate to the folder:

cd C:\RAK4631 Bootloader to RUI v3\

Run this command (replace <COM#> with your actual port number):

nrfutil.exe dfu serial -pkg rui3_rak4631_latest.zip -p COM<COM#>

Download Signal Meter Code
Download the .ino file:
RUI3-Signal-Meter-P2P-LPWAN.ino
Upload Code via Arduino IDE
File > Open > Navigate to the downloaded .ino file.
Double-click the restart button on the board.
Tools > Board > WisBlock Boards > Connect the correct COM port for RAK4631.
Upload the script.

However when I tried to upload the script I got this error:

Do you have any advice on how to overcome this issue?

If you downloaded only the INO file, that is not enough.
You need all .INO, .cpp and .h files from that repo:
