I have a new Thingy:91 followed the instructions but no yelow flashing, stays on blue flashing. What is required to get this connected please. Thanks

I  have your full eval board as well, I also have multiple NB_IoT sims from Vodafone but have not tried them yet. How do I get your Thingy:91 unit with your sim running please.

Thanks in advance for your help

Hi.

Have you activated the SIM card in nRF Cloud?

Have you confirmed that the iBasis SIM card is working in your country/region?

You can find a list of iBasis' coverage here: ibasis.com/.../

The firmware on the Thingy:91 from the factory is using LTE-M. Is that supported in your location?

You can find a map over LTE-M and NB-IoT support here: www.gsma.com/.../

Have you updated the firmware (both application and modem) on your Thingy? If you have not, that is highly recommended.

Best regards,

Didrik

Hi Didrik,

Thank you for your reply. 

Yes I activated the sim successfully

Ireland is NOT on the list on iBasis

Ireland is NB_IoT only

I already have a vodafone NB_IoT sim (20 of them in fact for trials)

How do I get the Thingy:91 configured to work with a vodafone sim , on NB_IoT in Ireland. Do you have a guide for this please. I already have the main eval board for the nRF91 but have not used it yet.

If you could help with instructions and a guide it would be very helpful

Thank you

Paul

The nRF91 should work with the Vodafone SIM card without any issues.

However, you will need to replace the application with an application that supports NB-IoT.

The best way to do this is to connect the "Debug out" port to the debug port on the Thingy and use the "Programmer" application in nRF Connect for Desktop to flash the new firmware to the Thingy. Note that you should select the DK in the programmer application.

If you do not have the appropriate connector, you can set the Thingy in DFU mode by holding the button while powering on the Thingy. You can then use the programmer application to perform a DFU operation to the new firmware. If you have any problems with the programmer application, you can also use the command line by following this guide: https://devzone.nordicsemi.com/nordic/cellular-iot-guides/b/getting-started-cellular/posts/thingy91_2d00_fw_2d00_update_2d00_mcuboot

I have attached a folder with pre-compiled hex files for both "regular" programming and DFU. You should use one of the *_nbiot_* images. If you are not able to connect with the "normal" nbiot image, you should try the nbiot_legacy_pco image. This is because not all networks support the new ePCO feature introduced in LTE-M and NB-IoT.

If you want to use the asset tracker example they won't work, the trial SIM only work to fixed IP addresses. PM me if you want more info.
