Information Unlimited switching between LTE and GPS on nrf91 SoC

[smauelGIS]

Hello,

I received information that i could turn the modem on and off not more than 60 times within an hour.

We are however working on a real time system, which may require more than this limited number, so;

1. Is there a hardware solution from nordic that can give us unlimited number of switching, to collect GPS data and send using LTE?

2. Is there a firmware solution, if so how long should we wait for this firmware solution.

Thanks and Regards

Hi.

The limit of 30 connections per half-hour comes from the network, so there is no way around that unfortunately.

 

2. Is there a firmware solution, if so how long should we wait for this firmware solution.

 We already support GPS while in PSM and eDRX. We are also working on otherwise improving the GPS + LTE experience, allowing for even shorter timeslots for the GPS stack. However, the shorter you run the GPS stack, the less time it gets to search for satelites, and the longer it will take to get a fix.

 

1. Is there a hardware solution from nordic that can give us unlimited number of switching, to collect GPS data and send using LTE?

 The limitiation is in the network, and the nRF9160 is not able to run the GPS and LTE stack at the same time, so you can not solve this problem with the nRF9160 alone (except the above suggestion of not disconnecting LTE). However, you might be able to use an external GPS. That way, you can run the GPS and LTE at the same time as you are no longer bound by the limitations of the nRF9160.

Best regards,
