GPS Sample code works, but how do you reduce power?

[stevenminnick]

I got this project to compile and work: https://github.com/NordicPlayground/fw-nrfconnect-nrf/tree/master/samples/nrf9160/gps

I have the latest radio firmware at this time: 0.7.0_29.  I'm actually using a DK 0.8.2 which required an external antenna, but when I use one it works fine.

I measure constant current around 30mA when doing this. 

According to this, there seems to be 2 lower power modes below what this sample is using: https://infocenter.nordicsemi.com/index.jsp?topic=%2Fps_nrf9160%2F_tmp%2Falta.nRF9160%2Fautodita%2FCURRENT%2Fparameters.id_current_gps.html&resultof=%22%67%70%73%22%20%22%67%70%22%20

Also some information on lower power modes here: https://infocenter.nordicsemi.com/index.jsp?topic=%2Fps_nrf9160%2Fgps.html&resultof=%22%67%70%73%22%20%22%67%70%22%20

Is there any guidance on getting the radio into these lower power modes?  Are these modes implemented in the radio firmware at this time?

Hi Steven,

For the current modem firmware version, the GPS is not "power optimized" and only supports cold start. 

However, there will come a more power efficient modem firmware with regards to GPS in the near future.

Please contact your RSM for more details regards to the roadmap, if you do not know who that is please send me a personal message on Devzone and I will help you out.

How about now?  1.0 was released a couple weeks ago.  Any chance that was in that release?
