Autopi 4G Edition - doesn't wake up

Subject of the issue

We tested on couple of cars, once a car is shutdown and key is removed. Autopi goes to hibernate after 30 minutes and does not wake up until car is started again.

We are building Car Sharing and we need to wake up device when somebody approach the car. But when device goes to hibernate it does not accept calls or sms.

What to do?

and it drains a battery in less then 30 minutes

Its brand new battery with start stop functionality (it has alot of power)

Hi @bruno

Thank you for reaching out.

The batter level show in the events list, is an indication of what state the battery is in currently. When the battery hasn’t been charged in a while, it will start to drop and the state will change. The standard power setup of the device is very conservative set. This is because we want to make sure that the power profile matches as many customers as possible.

However, we do know that some customers may have other needs. Because of that its possible to configure the power settings on your own, and make them more or less conservative. You can do that under settings->dongles->advanced->power:

With the standard setting, the device should be able to continiously come online for a couple of days, before going to into hibernate. I recommend that you play around with the Inactivity After Sleep interval. If there is no reason for the device to wake up, then just let it remain powered down in normal sleep.

In the next release, we are introducing an new power funciton called “airplane mode”, where you can control if the modem should stay awake during normal sleep.

An alternative option is to configure the sleep timers to always go into hibernate during nightime, to conserve power when you know the device is no being used. However, its currently not possible to set dedicated sleep periods directly from the AutoPi Cloud at the moment. But this may be something you can configure on your own using the Jobs.

Hope you can use the answer in your setup.
