If you registered your BEEP base via the BEEP base app, and it is visible in the Devices tab in the BEEP app, the data of your BEEP base will be available as soon as you can see the LoRa connection of the BEEP base in the TTN being connected.
If you do not use a BEEP base, but built your own device, you can check this article to get your device data in the BEEP app.
