[solved]No data in 'Applications> node join problem

End Devices (Nodes)
1

Hello
I can see the data in TTN Console Gateway.
There is no data in ‘Applications>…>Data’ or ‘Applications>…>Devices>…>Data’.
Device status is ‘never seen’.

I use:

I have configured the ttn application using the instructions -
https://www.thethingsnetwork.org/labs/story/soil-moisture-sensor-experiment-with-lorawan-atim-rtu-mode-ready-to-use

I tried:

  • to use AppKey with Big endian and Little Endian.
  • restart Gateway
  • restart ATIM device
  • delete and create again - Application and Device on TTN console
  • check and uncheck ‘Frame Counter Checks’

What am I doing wrong ? Can I somehow debug the connection?

  • did it worked before with that node ?
  • is your gateway connected to TTN … working, you receive data from other nodes ?
  • if yes show a screenshot from your node trying to connect
  • did you leave your browser window open ?

Hello,

In ATIM devices, only EUI (DevEUI and AppEUI) are read in little endian.
DevEUI and AppEUI bytes must me reordered in big endian before registering device on TTN

AppKey bytes MUST NOT be reordered.

  • ATO70 : DevEUI (Little Endian)
  • ATO71 : AppEUI (Little Endian)
  • ATO72 : AppKey (Big endian)

Do you have a screen dump of your TTN console ?

Thank you for your response.

  • no, it never worked with this ATIM device
  • yes, it works with Microchip Lora Mote
  • I attach screenshots from Tera Term with connection to ATIM usb dongle and from the console ‘Gateway Traffic’ and ‘Application Data’.
    I attach screenshots of running Microchip Lora Mote on the same Gateway.
  • yes, i leave browser window open

Thank you for your response.
Yes, thank you, I know about ordered of the keys. I used the instructions to which the link was given in the first post.

Hello,
If OTAA was enabled, you should see the JOIN request on your Gateway console before the first uplink.
Your ATIM device seems to use ABP instead of OTAA.
Check the content of ATO83 register.
The lower bit of ATO83 register must be set to 1 to enable OTAA.

Thank you bq1. That was it. Now it works. OTAA wasn’t enabled.
I did:
ATOS83 = 37
and restart.
It works. Thanks a lot. My stupid mistake.
