Pycom's LoPy as node device can't show in Application Data

[jiangyunwei]

Hi,
I’m using LoPy from Pycom as a single channel gateway to TTN, and another LoPy as node device in ABP mode with US915 frequency.
Right now the gateway could push the data packet to TTN as below, I can see the data traffic:

Also I can see the node device is connected and the increment of upframe:

But there is no data in application data:

I wonder if it’s because I didn’t add any decode function for the application, but not sure right now.

Hope your guys could help me!

maybe node and single channel GW don’t operate on the same frequeny … you should see the data in the application.

Hi, thanks for reply. I also use LoPy as the node device, and set frequency to 903900000 in both gateway and node. And the payload in the event data of the data traffic seems encrypted?
