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?

Hi Hoang,

I have not got a Thingy:91 nor read up on the specifics of the device. I would suggest flashing the gps sample application to the device and seeing how the device responds to that program. That would give you an idea on if it is capable of GPS communication. I imagine that the device does have an on-board GPS antenna.

Thanks so much MJD093

It's encouraging at least that you have been able to successfully connect to nrf cloud. There are many reasons why the GPS data has not been acquired, such as interferance, poor satellite to UE visibility, tracking multiple satellites but they are not providing a fix, etc.

The GPS application will give you more information on the status of your UE to satellite link.

The pull request I referred to with the asset tracker example should work fine with nRF Cloud. I have tested it myself & it seemed to work perfectly. I will take a look at this case tomorrow morning when I have access to my Thingy:91 again.

Hoang If you want to see logging on the Thingy:91, it should suffice to open up the link monitor app, connect the Thingy:91 via USB, turn on the Thingy & then click off the Auto device/port filter button in the lower right hand corner of the Link Monitor app. Then, you should be able to choose between two different serial ports. Try both & one should give you UART logging of the Thingy:91. I am testing this now & will update the thread with a response soon.

Hi Bjørn Kvaale, Ja, I can connect to USB and see the logging on thingy:91 now. I am running gps example, but it couldn't get a fix.

[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.

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