Questions for Thingy 91

[Jeffery]

Dears

I listed my questions below. Thanks.

1. About GPS searching and fixing, I tried Thingy91 outdoors.

- When Thingy91 connected to LTE, did LED shall blue color?

-  Then, I pressed the button more than 10s, LED became purple color. As user guide said,

   LED will turn green color if GPS fixing. However, I wait half an hour, LED still kept purple color.

   NRF Cloud didn't get GPS data. 

2. For Thingy91, where can I get asset tracker source code of NRF9160,

    and board controller source code of NRF52840? 

3. For recharging battery by USB power, shall I keep SW1 of Thingy91 ON? 

Thanks.

Hi!

1. You most likely haven't gotten any GPS fixes.

thingy:91: outside? far away from the buildings. You can connect THINGY:91 to the serial port to see the report 

It took me around 1mn to get the fix ( after find 5-6 satellites). Or you can use external antenna 

I recommend following this advice.

 

2. The asset tracker source code can be found in the nRF Connect SDK under applications, and the code for the nRF52840 can be found here

3. Yes, SW1 must be on for the battery to charge. More information on this can be found here.

Hi Heidi-Irene Harvey Sollie,

Does it contain config and dts files, not the code for nRF52840 ?

I am looking for the code for NFC and BLE on the thingy:91 also, but I think it hasn't come yet. 

Thanks,

The board controller for the nRF52840 on the Thingy:91 is a pull request found here: 1011. It's not so much a board controller than a USB - UART bridge. The source code is under review but functionally it should be okay.

There is no example code using NFC and BLE for the Thingy yet, unfortunately. However, the libraries are out on the NCS github, so you can develop your own.
