Thing Park not forwarding data to my endpoint

[quote=Rick S.]Hi [user=24365]JCL[/user] , Welcome back! Im sorry to hear that you can't send data to your endpoint successfully. I have to say that my knowledge about these kind of issues on ThingPark are not my speciality. So I want to discuss this with my colleagues from the IoT servicedesk. Can you please tell me which steps you took to send the data? And what is the DevEUI of the device you used?[/quote] Hi [user=8294]Rick S.[/user] What do you mean as steps to send the data? I have several lora devices that send data out, this data is forwarded ( or it should be) to my url endpoint. The DevEUI's are 5354444B41473038 and 5354444B41473037. [quote=Rick S.]Besides, when i click on the url of your endpoint I get an error. Is this the exact same endpoint you've used with success in the Developer Portal?[/quote] yes it is the same endpint that I was using in the Developer Portal and it was set as succes. If you click on my url you should't get anything, that is not an

Why I cannot connect to my devices with OTAA?

[quote=Rick S.]Hi [user=24365]JCL[/user] Excuse me for my very late reply! I have been on vacation for 2 weeks and I have completely forgotten to answer your question. I'm sorry! If the device is rebooted, this does not immediately mean that the device is no longer registered on the network. As long as the device is registered on the network, the network will reject a new Join Request.[/quote] Still my OTAA devices are rejected by kPN lora network while joining, what can I do?

Is the Developer portal under maintenance?

[quote=Tim][quote=JCL][quote=Tim]That's very unfortunate. I haven't noticed the downtime. Good to hear the developer portal works again now! Please let us know if you encounter any problems again.[/quote] Hi [user=227]Tim[/user] I have experiencing again issues with the dev portal, today from 02:00 am, it has stopped working...[/quote] Strange, there was no maintenance know to me. Did you only experienced issues while logging in or were messages also not being deliverd?[/quote] Both, I cannot login and the delivery stalls... Could it be a server backup of the site?

Is the Developer portal under maintenance?

[quote=Tim]Hello [user=24365]JCL[/user], for me the developer portal works as expected at the moment. My messages are being forwarded and received. I'm not sure if there was any downtime this morning, I didn't catch a notice about it. Can you try again if the developer portal works for you as well?[/quote] The portal seemed to be out from 5:09 am till 10:50 am of today, I didn't get any message in that time span, and I was not able to login from 9:00 till 10:50.

Why I cannot connect to my devices with OTAA?

Hi [user=8294]Rick S.[/user][quote=Rick S.]Hi [user=24365]JCL[/user], This is also the reason why the network doesn't accept your Join Request. [/quote] But that means as well that my device can not send a new rejoin in case let's say that it is rebooted?

Does the developer portal decrypt Lora payload?

[quote=Rick S.]Hi [user=24365]JCL[/user], I saw that you also placed this question under the topic [url=https://zakelijkforum.kpn.com/lora-forum-16/lorawan-security-encryption-and-authentication-10957/index1.html#post22543]LoRaWAN Security: Encryption and Authentication[/url] . Meanwhile my colleague Lennart Nordin has also given an answer to that. Have you seen this answer? [quote]In the Developer portal documentation it states that: "Messages are forwarded unencrypted. The developer portal already decrypts the LoRa data using the randomly generated AppSKey. No further decryption is necessary. In the Commercial LoRa Service end-to-end encryption is supported. All payloads are hexadecimal however, meaning they have to be decoded in some way to be used in applications. The decoding scheme depends solely on what the device manufacturer programmed in your device." Does this answer your question?[/quote][/quote] Thanks [user=8294]Rick S.[/user], I saw the answer and I menti

Kind regards, Lennart[/quote] Hi [user=16304]Lennart Nordin[/user] thanks for your answer, it answers my question partially. In that the payload that I am getting from the developer portal is not decrypted at all. When the forwarded payload hits my backend, the payload that I am getting is this [i]\"payload_hex\":\"940adfc976bffbf80dfe452c615a0410465d3549651967260c948e03\" \"value\":\"940adfc976bffbf80dfe452c615a0410465d35496

Why I cannot connect to my devices with OTAA?

[quote=Rick S.]Hi [user=24365]JCL[/user], Unfortunately, i can't check specifically why the OTAA Join Requests didn't go trough. Maybe this question is unnecessary, but did you check the topic [url=https://zakelijkforum.kpn.com/lora-forum-16/over-the-air-activation-otaa-of-devices-11076]Over the air activation (OTAA) of devices[/url]. I will ask the specialists if they can i check what went wrong with the Join Requests. In the meanwhile i can delete de device from the Developer Portal, so you can send a new Join Request for these device. Is that an idea?[/quote] Yes you could delete those OTAA ones if possible, all except the one ending on 0CD1 since that is ABP thanks!

LoRaWAN Security: Encryption and Authentication

[quote=Lennart Nordin]Hi JCL, That is indeed the reference code I was referring to. There is also [url=https://github.com/iotacademy]additional code[/url] specifically for node-red available on Github. This was posted by the IoT Academy. This might also be helpfull in getting started. If you are using node-red I believe you should indeed perform the decryption there as well. Kind regards, Lennart[/quote] Then if I used node-red and if I understand well, first I have to get the LoraWAN payload from the DevPortal performing a SHA256 Check onto it, thus I will get the LoraWAN payload encrypted with the AppSKey. Secondly, I wil have to decryot that payload with the AppSKey in order to get my real payload. Is this reasoning correct? Thanks!

Where should I get it? Thanks! EDIT: I overlooked, in the link it is explained as well that [quote]Note that you have to change the LRC_AS_key to match your SHA key from your profile in the Developer Portal or the Application Server profile in the Thingpark deviceManager.[/quote]

Hi [user=8294]Rick S.[/user] [quote=Rick S.]Goedemiddag [user=24365]JCL[/user] Welcome to the IoT Community! I apologise for my very late response. We have been busy these days and that's why i can check your problem so late. I've looked up your Developer Portal account and I see 4 devices in total. One of the devices (DevEUI ends with0CD1) is now accepted by the network and for as far as i can see it is working as it should, right? Can you tell me what you did to get this device working? The OTAA Join Requests from the other devices do not seem to have come through well.[/quote] I made that working because I set up that node as ABP instead of OTAA, and yes it does work fine. However, I am interested on having OTAA as configuring my nodes. Why don't the OTAA Join Request go through ? Are the address wrong or other params? Thanks in advance!

This should probably help you along. Kind regards, Lennasrt[/quote] Hi Lennart, Do you refer to this code https://github.com/kpn-iot/lora-reference/blob/master/payload-decryption/PayloadEncryption.php ? In case it's so, since I am using node-red to read the payload I should implement such functions in node red so that I can decrypt my data right? Kind regards

LoRaWAN Security: Encryption and Authentication

Hello, I was wondering, why doesn't the dev portal decode the data from LoraWan if the link between the appplication server and the one of KPN is already trusted through SSL? I am having troubles to decode the data in my application server, since was expecting the data to be already decoded from KPN portal. Could you point me out a way to decode my payload? Kind regards
