Facing problem in connecting Nordic Thingy 91 to nRF Cloud

[Lalit Kumar Baghel]

I am using Nordic Thingy 91 Kit.

I have uploaded modem and application firmware URL : Nordic Thingy:91 - Downloads - nordicsemi.com

I am facing following problem while connecting Nordic Thingy 91 to nRF Cloud.

There was an error adding your device: No device found for this id. The device has not yet been provisioned. Troubleshoot nRF Code 40412

Hi,

Was the Thingy:91 connected to nRF Cloud when you tried to add it to your account?

The LED should be yellow when the device is ready to be added to your account.

Hi,

I tried to connect thingy to cloud but showed error 40412, and led status was blue only no yellow color.

 Then the Thingy:91 had not yet connected to nRF Cloud, and was therefore not yet ready to be added to your account.

To avoid any confusion, let me clarify a bit what I mean:

"Thingy:91 connected to nRF Cloud": The Thingy:91 is connected to the nework, and has established a TLS and MQTT connection to nRF Cloud's servers. This should happen automatically unless the Thingy:91 encounters any problems. This should also happen regardless of whether the Thingy:91 has been associated to any nRF Cloud accounts.

"add Thingy:91 to your account": This is where you log in to nRF Cloud, press the "+" button, and enter the device's details. If this operation is successful, the device will now appear in your list of devices, and you can see the data it reports.

 This means that it was still trying to connect to the LTE-M or NB-IoT network.

What SIM card are you using?

Are there LTE-M or NB-IoT coverage where you are?

Does you SIM card and subscription support your local LTE-M or NB-IoT network?

Is the application configured to use LTE-M or NB-IoT to suit your local network and SIM card?

Can you connect the Thingy:91 to a computer, and send me the log it prints?

Best regards,

I am using Sim Card form iBasis .

I think i don't have NBIoT coverage in my area.

Can you please suggest me some way so that i can see some GPS data on PC without LTE-M and NBIoT network.?

The GPS sample does not require any cellular network connection.

But, to be able to program it to a Thingy:91 without any external debugger (such as an nRF91 DK), you will have to add CONFIG_BOOTLOADER_MCUBOOT=y to the prj.conf file, and copy nrf/application/asset_tracker/configuration/thingy91_nrf9160ns/pm_static.yml to the project folder. After building the sample for the thingy91_nrf9160ns board, you can use the Programmer app in nRF Connect for Desktop to program the Thingy:91 with the app_signed.hex image in <your build folder>/zephyr.

If you do not get any log from the application, you will have to make a file called mcuboot_olverlay-rsa.conf in your project folder with the following content:

CONFIG_BOOT_SIGNATURE_TYPE_RSA=y
CONFIG_BOOT_SIGNATURE_KEY_FILE="root-rsa-2048.pem"

and the following lines to your CMakeLists.txt file, right after the line specifying which CMake version to use:

list(APPEND mcuboot_OVERLAY_CONFIG
  "${CMAKE_CURRENT_SOURCE_DIR}/mcuboot_overlay-rsa.conf"
  )

But, I also recommend that you contact your Regional Sales Manager, who probably knows more about your local situation than I do. It might be that there are some other network provider in you area with coverage. If you do not know how to contact your RSM, you can send me a private message with your location, and I will provide you the contact details.
