Hi,
I’ve got some devices with hardcoded Appkey, AppEUI and DevEUI.
I’ve got all the information, and when i run my gateway in Network Server mode I can see the data coming in from devices (meaning information i have matches credentials in the device).
However, when i create an Application on TTN and add to it my own AppEUI (00-13-7A-10-00-00-00-00), I cannot get the devices to connect.
I’ve tried this on a few different devices, ones that allow me to use any AppEUI+Appkey+DevEUI all of those devices work fine if they use AppEUI generated automatically by TTN(e.g. 70-B3-D5-7E-D0-01-28-47), but no matter what i do they wont work with a modified AppEUI.
Tried getting my App to use AppEUI #2 (the one that is hardset by manufacturer of devices i use) - getting an error…
Tried using default AppEUI- works,…tried using 3rd AppEUI - generated by TTN as well - works…
Hi @sronan, indeed i have found a solution - you need to contact the distributor of Netvox devices and ask them about procedure of changing embedded APP EUI. It is possible ( all that you need to do is run a network server, connect your devices to it with known credentials, and send a message with a specific byte sequence). Unfortunately, this information is not publicly available (no idea why…), but if you contact distributor they MIGHT know it - if not contact Netvox representatives - they will give you instructions (its VERY similar to how you change period with which the devices report).
I cant share the info as i am bounded by confidentiality agreement, but i can say - im pretty happy with the quality of devices…only thing documentation is lacking, and changing APP EUI is unnecessary complex.
Run the Conduit Gateway in NS mode and change the frequency band to US915 (Netvox devices are set up with AU915).
Set up the APP KEY & APP EUI in the GW.
Set up a mdot US915 with this credentials and made successful join !
Then,
Go back to AU915 in the Conduit.
Try with Netvox device, but no join, and no failed join request.
By the way, The default uplink channel frequencies of these AU915 devices are 916.8MHz, 917.0MHz, 917.2MHz, 917.4MHz, 917.6MHz, 917.8MHz, 918.0MHz, 918.2MHz 917.5MHz(@BW500)
Is there anything missing ? How I can check that the frequency change is well set up?
How I can check this? Tell me the commands please, I’m not a Linux expert
Besides, I also enter the webinterface of the Conduit and select “DISABLE” on the LoRaNetwork, is this ok?
Here is the result:
{
“code” : 401,
“error” : “not logged in”,
“status” : “fail”
}
The GW is now connected to TTN, in AU915 band.
I made a succesful join with a mdot in AU915, of course.
The problem is with the NETVOX devices. I cannot make them work.
I had created the Application and registered the device. (copying the APP_EUI & APP_KEY from Netvox)
Before, I made a local configuration (without using TTN), and the device worked!! It had joined and send data.
But, when using TTN, the NETVOX device doesn’t report. And I do not see any traffic in Gateway console too.
This is exactly what happens.
Maybe these devices are not compatible with TTN?
@VS1 can you send me more details about your solution? I need to send downlinks from private NS to the device in order to change the App_EUI and Key?
Just been thru this entire thread.
Can someone advise the netvox default appeui, appkey? Surprised this isnt documented in the R311A manual. Still hunting payload document also. Any assistance appreciated.
I have been using something similar to this. I have purchase NetOp devices that have fixed App EUI, Dev EUI and App Key. The problem i encountered is that the the app EUI is generated by TTN. But i found out you can change it manually in add EUI. You will need to delete the current EUI that is generated by TTN and add EUI in mange EUI tab.
After that i manage to add the device in TTN.
The devices from my distributor have an App UI of ‘00 00 00 00 00 00 00 00’ but in TTN console its not allowed to create and App EUi with all zeros i have over 100 devices and the Embedded App EUi can only be changed by Using an Android App via NFC. Is it not possible to some how create an App EUi with all zeros ?
Hey I want to use sensor which our firm produced working by LoraWan. I have gateway connected and now I do not know how to add AppEuı to my sensor and also how to match with TTN. Could you help me about this please?
Dear Sir, could you help me about connecting our product sensor to TTN. our firm produced a sensor without apıEUI and devEUI. How can we manage these to connect TTN?
@smgssmn have you read the available documentation (TTN & TTI?) and reviewed videos etc… note all zeros under new TTS(CE) aka V3 ok now for AppEUI … but not recommended and if a manufacturer vs hacker suggest go buy a block…
Dev EUI is really a must have and is effectively the serial number/unique identifier in the network - the DevAddr will change and may be used multiple times so combination of AppEUI & Dev EUI is the principal way to identify a given device…
If in doubt and for short term solution you could always try this option as a bit of a hidden gem (not currently linked from his home page) - suggest you cross Nick’s palm with silver in appreciation (he wont ask!) if you go that route for (just a few mind!) EUi’s Random EUI or Key generator you really need to get your own allocation…or buy some EUI chips…
