Amazon Deeplens 设备注册成功后离线，无法部署项目

Question

I'm all set following the installation instructions but suddenly the cam went off-line in the AWS Console (Device Status: Offline)(when I installed the device the status was online) Running version 1.2.3 with Linux kernel 4.10.17 I can ssh into the cam, I have a working wifi connection in the cam, I can update the cam software and I can see the video stream on the cam.

Do I need to restart an awscam service (if there's such service)? Or maybe reboot the camera (just did that, no dice)?

I have no idea why this is happening (I haven't updated the camera software or Ubuntu) BTW the effect of this is that the deployment of a project to the cam gets stuck (blue message with 0 progress)

Answer 1

I have found this can happen regularly as I power on/off the camera daily as I experiment with it. I've found re-install the awscam module works every time. You need SSH onto the device and run the following command :

sudo apt-get install --reinstall awscam

Wait about thirty seconds for the newly installed awscam to restart and you will see the device come back online. You don't need to Re-register the device or edit settings, just re-install awscam. Some more details are contained on the AWS forums, for example : https://forums.aws.amazon.com/thread.jspa?threadID=281899

Answer 2

We found that the AWS DeepLens has a single network adapter running both wifi hotspot and wifi connection. If you connect to its hotspot functionality it will drop the main wifi connection. Then it will try reconnect to wifi and drop your phone/machine connection and repeat this process at will.

Connecting a monitor (mini-HDMI to HDMI cable), mouse and keyboard will allow you to see what it's actually doing. Ours was stuck on GUI password prompt for wifi. Default password for access on ours was "aws_cam" which is not in the documentation.
