Failed to get information off device No valid sensor readings received from device

I want to add some more training data to my project on another computer.
I setup the edge-impulse CLI tools no problem.
I flashed the same firmware I used before: arduino-nano-33-ble-sense.ino.bin
Then run the data forwarder. It connects to the site no problems and then fails to get any data:

The firmware is on there:

Is there a reference for the AT commands? Can I run some manually to confirm that the device really is sending data.

Any others ideas for debugging this?

@mattvenn With the prebuilt firmware use edge-impulse-daemon. The data forwarder is only if you have written a custom sketch
