Hi RAK Team,
I am looking for a reliable way to cross-check LoRa communication by measuring the RSSI values in dBm (signal strength) and SNR. Could you please suggest which modules or field-test devices are best suited for this purpose?
Do you want to test LoRaWAN or LoRa P2P (or Meshtastic)?
For LoRaWAN, we have the RAk10701 Field Tester which can give detailed information for up- and down-links. RSSI, SNR, missed packets, …
It requires either our WisGate gateways with WisGate OS 2 or a customer backend.
For LoRa P2P (and limited usage with Meshtastic), we have the RAK10706 Signal Meter which has a P2P mode. It will show received packets RSSI and SNR values.
For both p2p and lorawan, I am using RAK3172 .This device will work for this module? need to cross verify the signal level with my measurement in my product
Both devices are using the RAK4631 internally.
We do not have a tester that uses the RAK3172.
Only option is to use a WisBlock with the RAK3372 (RAK3172 for WisBlock) and write your own application or check if the firmware of the above field testers will work on the RAk3172.
For the version with the TFT touch display, RAK10701, I am sure it will not fit into the flash of the STm32WLE5.
The firmware of the RAK10706 might work ==> RAK10706-Signal-Meter
I never tried to fit it into a RAk3172, some functionality will have to be removed, e.g. saving on SD-Card, maybe GNSS logging, …
Not sure.

The signal meter with [RAK10706 Signal Meter) will monitor the rssi and snr value of my product which used RAK3172 ?
Yes, it will show the RSSI and SNR levels of packets received from the RAK3172 or any other device when using LoRa P2P.
Hello @beegee
I am currently working on developing a LoRa RSSI / SNR dB meter similar to the RAK10701 Field Tester Plus using RAK3172 and ESP32 hardware.
For initial development, I plan to run the setup over serial monitoring, and later integrate Wi-Fi and Bluetooth features on the ESP32.
I would like to request the following information to help in my development:
- RAK10701 / RAK10701-Plus schematic or block diagram – to understand the hardware architecture, interfaces, and connections.
- Firmware or reference source code – any available example, partial code, or GitHub link for field tester logic (RSSI/SNR measurement, packet counter, uplink/downlink handling).
- Any supporting documentation or hardware details (display type, MCU interface, power design, or antenna section) that can help replicate similar functionality with RAK3172 + ESP32.
If the schematic or firmware is not publicly available, kindly guide me on how to request access or if there is any alternate RAK module/project (like RAK10706 Signal Meter) that I can refer to for this purpose.
The hardware of the RAK10701 is quite simple:
- WisBlock RAK19007 Base Board
- WisBlock RAK4631 Core module (nRF52840)
- WisBlock RAK12501 GNSS location module
- WisBlock RAK14014 TFT module with 240x320 pixel touch screen TFT
- RAK10701 is using a custom version of the RAK14014 with additional button function, not available as separate module
- WisBlock RAK1904 3-axis acceleration sensor
The Unify enclosure with the TFT display mounting option is not available as separate part, but you can use a
- 3D printed lid ==> RAK Unify Enclosure TFT Lid
- 3D printed enclosure for TFT display ==> RAKwireless Wismesh Pad V2
Firmware for RAK10701 ==> RAK10701-Field-Tester This is for the RAK10701, not for the PLUS version
As everything is based on WisBlock modules, you can find details in the documentation for each of the above listed modules.
Thank you so much. I will try to complete. if i have any doubt or technical guidance needed, i will get back to you.
