Hmmm.... the logs seem to indicate that the device hasn't come online since yesterday at just after midnight. I can see there is a pretty old version of firmware, and the device does indeed seem to be unresponsive.
Can you try one thing? Flash the Photon/P1 with the same gateway app (or new one, really doesn't matter). That should reset both the Photon/P1 and the nrf51, forcing it to reboot and reconnect. Once you do this, you can watch the device connect in the dashboard and then wait for the Photon/Pq to publish it's device ID (should happen a few seconds after it comes online) and then try to go to console.bluz.io right away.
The device does come online, so it must be working.
Is the Photon online? There was an issue in an old version of the gateway where if the WiFi cut out for 60 seconds the Photon would go into listening mode. The new version of the gateway library will fix that. If the Photon is online, I would try the above.
