Best possible LTE configuration for GPS fix

[Ramani]

I have a thingy91 device and want to implement the following requirements.

Expectation:

NRF9160 should remain in deep sleep mode and on the button click event do the following activities and again go to deep sleep mode:

1) Register LTE-M/NB-OIT and connect to MN(Mobile Network)(IBasis simcard),

2) Acquire GPS(I am using AGPS)

3) Send this GPS fix to Azure Cloud.

NOTE: The duration of this button can be 1day to 4/5days. 

I am referring AGNSS example and configuration and applying it.

Can you please help me identify the best possible configurations to quickly use the GNSS to get a fix and put the LTE in Ideal mode: 

1) CONFIG_LTE_EDRX_REQ=y,  does this required for my requirement?

# PSM requested periodic TAU 8 hours

CONFIG_LTE_PSM_REQ_RPTAU="00101000"

# PSM requested active time 6 seconds

#CONFIG_LTE_PSM_REQ_RAT="00000011", is it possible to reduce to a minimum level of 2 seconds?

Please also explain which method is best for my scenario out of eDRX/PSM or both

Let me know if you need more details.

Hi Ramani i'm looking into your case

So the only thing you want to do is to send a location with an interval between 1-5 days?

Yes, runsiv , the interval can be 1day, 2day,..5 day.

In some cases, it can be 5 hours but it's very rarely.

runsiv , I forgot to mention that I use an external GNSS antenna.
