Thingy:91

[Hoang]

Dear, 

I received THINGY:91 from NordicSemi. I use 10pins cable to connect to nRF9160 DK to program for THINGY:91. 

and, I am using ncs_v1.0.0

I am trying to run asset_tracker application, 

and I am confusing about: 

1. which board should I select? I tried to use    ncs_v1.0.0/zephyr/boards/arm/nrf9160_pca10090

but after programming, the LED on THINGY:91 changed to RED color, and I couldnt connect it from nrfcloud 

I couldn't find pca20035 on ncs_v1.0.0. Do I need to use another version of ncs ?

2. How can I debug the output from THINGY:91

The terminal still shows the output from nRF9160 DK, nothing from THINGY:91

Thanks, 

Mvh

Dear Bjørn Kvaale

I found nrf9160_pca20035 then I tried to program asset_tracker to THINGY:91, pressed the button (long press) then connected to nrfcloud and put the THINGY:91 outside. 

"Waiting for GPS Data...."

How to activate GPS? Do I need to use the external GPS antenna? 

Thanks

Hi MJD093 Can you help?

[Bjørn Kvaale]

Could you please run the asset tracker example again from this pull request? I believe I have already sent you the commands to integrate the PR into NCS. Please let me know what the logging shows.

[Hoang]

I just got a fix from gps. It took for a long time. I will try with asset_tracker from joakim. 

[MJD093]

How long is a long time? What was the tracking stats like up to the GPS fix, were you finding satellites previously but no fix or did you only start finding satellites just now?

[MJD093]

Bjørn Kvaale I can't seem to find any information on the Thingy:91, what kind of GPS circuit is deployed on the modules? Is it a correctly matched antenna circuit or does it suffer from pre-v0.8.2 antenna matching issues?

Ok, 225 seconds is a long time for a fix but 6 satellites is very encouraging, I recieve 7 satellites from my location and that's using a Molex 206640 external patch antenna. That usually takes more than 2 minutes but i'm inside a building. You were outside correct?

[Hoang]

MJD093 225s is the best case, many others times couldnt fix 

[MJD093]

But you are outside correct? That's pretty poor for a device outside. Are you in an open location, a good 10-20 metres clear of any structure with line of sight to the open sky?

[Hoang]

MJD093, I am running the same example for thingy:91 and nrf9160dk, and I put THINGY:91 and nRF9160DK on the roof of my office, and nRF9160 DK got the fix location, but thingy:91 no. 

[MJD093]

Ok so you have or haven't gotten the Thingy:91 to acquire a lock? Little confused here
