@mbirrell, you’ve replied to a 6 month old message for someone who’s in the US so the Australian network settings may not apply here …
Hi Nick, yep I realise that. I have treaversed this forum a bit and have noticed the same problem quite a few times… maybe I should have put "Make sure your Router and hadler are the same - Router (Gateway) = , Handler (Application) = " would have been clearer for the people that can’t work that out… I mean this in a good way. There are plaenty of simple things that has taken me a long time to figure out.
i already installed the library and enter the dev eui and other keys in my sketch but i can’t get any traffic in my ttn
Can you show us the output from the serial port so we can see what the CubeCell is doing please.
Do you have a gateway? Or a gateway you can see the logs on? Or just a gateway at all?
Yes i have an gateway
Please can you use the Show Timestamp option so we know how often these messages appear. Please turn off confirmed uplink, it’s a burden on the gateway as it has to transmit, rendering it deaf to other uplinks at that time.
I’m not sure what all the other TX & RX activity is that is woven in to the two confirmed uplink sending lines - can you give us the url of the code base you are using.
The simplest code to start would be using ABP if you could configure for that as well.
Finally, please, no screen shots for text that can be copied & pasted, it stops us copying it in to other tools for analysis. See How do I format my forum post? [HowTo]

}Next time, please take a few seconds to properly format your post. Just cut-and-pasting code does not make a great message.
Im sorry about the post, Im new here and Im not used to the format writing. I thought if i post in arduino ide code format will be easier as i afraid there will be misintepretation.
By not adding formatting tags to your post the forum software will reformat it. By adding the [ code ] . . . [ /code ] (without the spaces within the brackets) tags you prevent it from messing with white space.
Ok, Mr. Kersing. Thank you
See this from my earlier message, it has all the instructions you need:
That log looks like the default code that comes with the device? are you sure you have uploaded your code correctly?
You’re in the wrong sub-band of US915.
You need to enable the 2nd bank of 8 channels, not the first.
uint16_t userChannelsMask[6]={ 0x00FF,0x0000,0x0000,0x0000,0x0000,0x0000 };
needs to become
uint16_t userChannelsMask[6]={ 0xFF00,0x0000,0x0000,0x0000,0x0000,0x0000 };
And yes, it’s confusing because bytes are being filled with words…

Thank you! I played with my Cubcell like a year ago and had no luck. Had some time to play again, and this fixed my issues instantly with their demo code.
I already changed to 8 channel gateway as previously I was using single channel gateway but still I didnt get any data traffic on ttn
There’s so little detail here I don’t know where to begin!
Which 8 channel gateway?
Does it show any information about its connection to TTN - like a log?
Does the TTN console show any information about your gateway being connected?
Do your CubeCell uplinks show up on the gateway’s log or internal console?

As previously explained, you are using the wrong channels
I already changed the sub band but still no data traffic
Show the new logs from both node and gateway
