Getting started with the Thingy:91

[Calin M]

Trying to get started with the Thingy:91

- It's connecting to NRF Cloud and reporting data.

Problems:

1. Keeps blinking blue and does not get a GPS lock. I did leave it near the window. I did hold down the button for more than 10 seconds as suggested in another post, to turn on the GPS. I'm in Vancouver, Canada and using the iBasis SIM. How would I find out if this is because my provider does not support power saving mode?

2. Is the LTE Link monitor supposed to work over USB? I connected it via USB but I get "No devices available". I did uncheck auto device port filter.

I don't have a NRF9160 DK.

Thanks!

#define UI_CLOUD_CONNECTED_COLOR	UI_LED_COLOR_BLUE

Do you see the LEDs change to Cyan color? -#define UI_LTE_CONNECTED_COLOR UI_LED_COLOR_CYAN

 have you tried to put it outside?

Do you see the LEDs change color to purple? The purple color means GPS is searching. I must hold until you see the leds change to purple (after cyan)

I have spent many days to figure out the iBasis SIMs do NOT work with PSM in Norway :( . You should try with a local SIM card with LTE.

I dont know what is wrong. have you tried to use another app, for example: termite. 

Hope it can help.

Hi.

1. As Hoang said, you should try outside. The LED should also change to purple when it is searching for a GPS fix. Also, as he mentioned, PSM might not work with iBasis SIM cards. You need PSM to be able to do LTE and GPS concurrently. I have asked your Regional Sales Manager about the situation in Vancouver.

2. What operating system are you using? If you are using Windows 7, you should watch this case for more information:

Thank you so much for looking into this!

I'll try again outside. The colour does change to indicate it's searching for GPS, it just doesn't find it.

Please let me know if you find out from the sales manager about the situation in Vancouver, BC

How do I determine if PSM is allowed or not? I read in another post that the system will report that PSM is enabled, but actually it's not.

If PSM is not allowed, will the thingy not search for GPS, or it will search and not find the GPS?

Thank you,

Calin

This was my problem when i tried to use iBasis SIM in Norway ( not support PSM):

IN the report, it said: PSM enabled, after long_press to active the GPS ( purple leds on), nothing will come, and it will be reset after 360s (CONFIG_GPS_CONTROL_FIX_TRY_TIME=360)

Good luck

Hi.

Sadly I have not been able to confirm if this is the issue, but our people in Canada reports similar problems of not getting a GPS fix with iBasis SIM cards.

I would recommend that you contact your local operator, and ask for information from them.

Best regards,

Didrik
