Thingy:91 enabling external GPS antenna.

[Juha]

Hi,

I'm using Thingy:91 and I have built and flash the asset tracker software. I have connected the external GPS antenna (MIKE3A or similar), see picture.

How do I check that the external antenna is used by the modem? How do I activate external antenna? Currently I'm not finding any satellites. I have made same kind of setup for the nRF9160 DK board and its working fine. I have updated also modem firmware.

Hi!

The modem should use the external antenna automatically if it has been connected properly. What application are you running in the device? Which NCS tag are you on?

Best regards,

Heidi

Hi,

I'm using the asset tracker application and I have cloned the master branch. I will check my connection again.
