RAk3172, Functional test on RWC5020 LoRaWAN Certification

Hello,

I am doing a pre certification test for our end device which is using the RAK3172 as an AT-LoRaWAN modem. And all the tests are passing and it is getting stuck on test 5.8.a which is for Change in TXPower for the module. Although the commands are being received the power seems to not be changing, and have even took the module approx 100meters away from the receiver, but alas nothing changed.

The rak3172, has the latest firmware available to it (RUI_4.2.3_RAK3172-E). and the following are the AT settings:

AT+DR=0
AT+RX1DL=1
AT+RX2DL=2
AT+BAND=4
AT+ADR=1
AT+TXPOWER=0
AT+CFM=0
AT+NJM=1
AT+PNM=1
AT+CLASS=A

Here is an image of the log:

Hi @Ryandiapsl ,

Welcome to RAK forum.

Based on the AT commands set, maybe you can try to disable ADR - AT+ADR=0. It can be that the TX power was being overridden by the ADR algorithm.

Hello Carl,

I tested the device by manually setting AT+ADR=0, and this change is applied successfully when entered manually. However, after setting the RAK3172 to certification mode using AT+CERTIF=1, I observed that the ADR value is automatically turned on to 1. In this mode, it is no longer possible to manually change ADR back to 0, as the function is blocked.

Could you please provide further guidance? As per Class A certification requirements, the unit is currently not passing the TX power test.

I have tested the following:
Certification by similarity (Passed)
Class A, EU LoRaWAN version 1.0.4 (TXPower Failed)

Thanks :slightly_smiling_face:

Hello Again Carl,
Image attached for reference of test:


I have attempted to put AT+ADR=0, but as soon as i do AT+CERTIF=1, ADR is overridden and set at 1, and of course ADR cannot be manually changed once put into certification mode of the rak3172.
Any other hints about this please? As this is the only test it is not passing when doing a Class A test on the RWC5020b tester.

Thanks, and look forward to hear from you.
