Getting started with Thingy91

I used the programmer on windows for this which made it quite straightforward, I have not used the command line. The fading led sounds like the default asset tracker program is running. I would recommand the get started guide and the tutorials:

You should probably create a new thread, as things may have changed a lot since several years ago.

Did you try the Thingy91 Getting Started Guide? https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/working_with_nrf/nrf91/thingy91_gsg.html

It loads a pre-build file, and connects to nRF Cloud, so not the same as blinky. But you it is pre-built (so rules that out), and also has steps to update the device firmware first.

Blinky (zephyr/samples/basic/blinky) did work for me, but there isn't any logging output, so you don't really know what is happening if the LED isn't blinking.

You could also try zephyr/samples/hello_world, to see serial output (or just add some printk() statements to blinky).

I usually add a bit of a delay at the start of the samples, otherwise I find it may output (e.g. errors) before the serial is connected (e.g. nRF Terminal in VS Code)

e.g.

void main(void)
{
    printk("0\n"); // or LOG_INF("0");
	k_msleep(1000);
	printk("1\n");
	k_msleep(1000);
	printk("2\n");
	k_msleep(1000);
	printk("3\n");

	printk("Hello World! %s\n", CONFIG_BOARD);
}

Hi folks,

Reusing an old thread since the question is kinda the same.

I'm trying to build and flash blinky sample into Thingy91, however I don't see it is blinking red.

Building code, then flash ./build/zephyr/app_signed.hex went ok. However after power cycle Thingy91, it has fading blue led in the light well or all rgb. I've tried to flash via "Programmer" and with nrfutil on Ubuntu 22.04 with the same result.

nrfutil device program --firmware build/zephyr/app_signed.hex --traits mcuBoot

Could someone provide a hint what might be wrong, so I don't get an expected result? SDK ver. 2.3.0, Thingy91 v.1.0.0

Regards,

Alex

In case this helps someone, this is the list of steps I went to to finally get an LED blinking:

Open nRF connect -> Toolchain manager -> nrF Connect SDK 1.8.0 -> Open Segger embedded studio
In Segger studio -> File -> Open nRF Connect project ->
- nrF connect 1.8.0
- Project: Blinky
- Board name: thingy91_nrf9160_ns
Project -> Configure nrf connect project -> menuconfig -> Filter by mcuboot. Ensure MCUboot bootloader support is checked
Build -> Solution
Navigate to Ncs\v1.8.0\zephyr\samples\basic\blinky\build_thingy91_nrf9160_ns\zephyr and obtain file app_signed.hex
Connect Thingy91 to computer using USB cable, power off and holding down button power on
nrf connect -> Programmer -> Open
Select Device Nordic Thingy91, click enable MCU boot.
Drag file app_signed.hex into right pane
In programmer, Click Write and Write
Uploading complete successfully
Disconnect USB cable
Power down and back up again
LED flashes

Hi,

See this https://github.com/nrfconnect/sdk-nrf/blob/main/boards/arm/thingy91_nrf9160/thingy91_nrf9160_common.dts#L26

led0 is mapped to red_led which is P0.29.

I've done all of that. Let me give you a for instance. In this link:

https://infocenter.nordicsemi.com/topic/ug_thingy91/UG/thingy91/hw_description/pin_maps.html

it refers to various pins, however, if you open the sample blinky, it refers to led0

where is the mapping between these two? They clearly refer to the same board but the documentation does not allow you to get started programming this device as there is no intellisense in code to give you a clue what led0 might refer to.

Why is it so hard to get started with this board?

Hi,

To get started, please follow the Nordic Thingy:91 Getting started guide.

To develop applications for the Thingy:91, you will use the nRF Connect SDK, which contains a variety of compatible libraries and samples. We also have a dedicated guide for development on Thingy:91, see Working with Thingy:91.

For more information on the Thingy:91 hardware development platform, see the Thingy:91 Hardware Description. If you have further questions, check out the Thingy:91 FAQ on DevZone.

Where is the getting started guide for programming this device?

Hi,

You should build with boardname thingy91_nrf9160_ns and update with app_signed.hex. After programming, power off/on the thingy91, it should blink with red.
