Enabling GPS external antenna on thingy91

[engineerN]

Hi,

I am using Thingy91 v1.6.0.

SDK : v2.2.0

I want to use an external antenna for GPS. The antenna I am using is: robu.in/.../

I connected the external antenna to the UFL connector labelled GPS on thingy91 board.

In the sample gnss, I modified below configuration:

"CONFIG_MODEM_ANTENNA=y

CONFIG_MODEM_ANTENNA_GNSS_ONBOARD=n

CONFIG_MODEM_ANTENNA_GNSS_EXTERNAL=y

CONFIG_MODEM_ANTENNA_AT_COEX0="AT%XCOEX0"

"

Now, when I build the code and flash to thingy91, I am not able to see any improvement in GPS receiving.

So, are above configurations correct or am I missing something?

How should I confirm if the antenna was switched to external sucessfully ?

Regards,

engineerN

Hi

Please check out this thread where my colleague Heidi explains in detail how to use an external GPS antenna on the Thingy:91.

Hi,
I went through the thread.
From the thread I can see that the antenna configuration suggested was:

• For Thingy:91, is it ok to use an external antenna with this configuration:
  • passive antenna with LNA enabled
  • active antenna with LNA disabled

The antenna I am using is a passive antenna with LNA. 
And I tried the above configuration. This is what I was able to understand from the thread.

Am I missing something here? 

Please help me in summarizing the solution for the external antenna thing, I am not able to get to a proper conclusion from the data.

Your help will be appreciated.
