Hello

for a project, I am interested in getting on touch with developers familiar with KPN LoRaWan as well as the development of IoT applications.

If interested, please contact me on my email : ensamine@gmail.com

Cheers

Hi KPN,

I succesfully receive lora packets witin the developer portal, as you can see in the added screenshot.



However, these packets are not received at the given destination endpoint. (a node-red application server). I know this endpoint works because the same evening I also did some tests with the uplink test button in the developer portal, and those messages were successfully received in node-red.
In my proxy logging I see the POST messages of the uplink test but NOT the lora packets from the developer debugger. Therefore, I almost certainly know the KPN source did not automatically forwarded the lora packets to my application server.

Can you help me in troubleshooting this problem?

Hello Martijn, welcome to the LoRa Forum :)

However, these packets are not received at the given destination endpoint. (a node-red application server). I know this endpoint works because the same evening I also did some tests with the uplink test button in the developer portal, and those messages were successfully received in node-red.
Could you try and sent some (new) lora packets from the device to your application server? We already know your DevEui (from the image - thanks!). If you can let us know at what times the packets has been sent, we can try to look them up.

Well, I have a practical issue, the packets you see in my screenshots are transmitted during my car trip yesterday evening. The timestamps in the screenshot are correct.
From home I don't have enough signal to the closest KPN antenna...

Since you now have my DevEUI, is it an idea to do the same car trip this evening so you check the log tomorrow or don't you save any logging.. I can't do a car trip during the day...

Hi Tim,

I did a new test this evening.
You can see the packets in the screenshot. The screenshot also gives you the timestamp of the packets.


I also did an uplink test, and again ONLY this packet was received correctly and the packets from the screenshot not. I can even show you my proxy logging as a proof:
By reading the proxy logging I also discovered that my server time is one hour behind. I have to fix this.
So, please calculate +1 hour of the date/time you read below. (ps. Time= parameter from KPN is correct)

As you can see below I did two uplink test from the KPN dashboard to /kpnlora on the 16th of january; 13:24:27.295 and on 22:00:24.552.

nodered.searocket.io 213.154.238.21 - - [16/Jan/2017:12:24:27 +0000] "POST /kpnlora?LrnDevEui=0059AC00001811BD&LrnFPort=1&LrnInfos=null&AS_ID=XXXXXX&Time=2017-01-16T13:24:27.295+01:00&Token=XXX HTTP/1.1" 200 60 "-" "Jakarta Commons-HttpClient/3.1"

nodered.searocket.io 213.154.238.21 - - [16/Jan/2017:21:00:24 +0000] "POST /kpnlora?LrnDevEui=0059AC00001811BD&LrnFPort=1&LrnInfos=null&AS_ID=XXXXXX&Time=2017-01-16T22:00:24.552+01:00&Token=XXXXXX HTTP/1.1" 200 60 "-" "Jakarta Commons-HttpClient/3.1"

The screenshot from the KPN dashboard tells me that there were lora packets received on the 16th of january on; 20:55:01, 21:00:01, 21:05:02, 21:10:07, 21:15:07, 21:25:05, 21:30:01, 21:35:01, 21:40:02, 21:45:00

None of them showed up in my proxy logging.

Is het nog steeds zo dat het Developer Portal alleen Class A ondersteund?
