nRF-9160-DK - LED 3 Blinking

[vkadal]

After flashing the nRF-9160-DK with the required firmware ( as instructed in this video https://www.youtube.com/watch?v=rMvW3HXLErk&feature=youtu.be), the LED 3 is flashing. Does that mean that all the firmware is correctly loaded?

Thanks for the input. Looks like the issue is in the SIM card. I was trying to test the SiM by inserting it in android mobile and I am not able to access the Internet. How to resolve this issue? I am in touch with my local service provider to check the SIM

Hi,

I asked internally, and as of now, there's no LTE-M support in India. However, there's support for NB-IoT in some places with the operator Reliance Jio, so you should contact them about whether there's NB-IoT coverage in your area, as well as to get a SIM card with support for NB-IoT.

By default, the modem starts in LTE-M mode in our examples, so if you're going to use NB-IoT you'll have to change that. If your sample or application uses the LTE Link Control driver, which the Asset Tracker application does, you can select NB-IoT with CONFIG_LTE_NETWORK_MODE_NBIOT.

You can also ask our regional sales manager in India, Mr. Gaurav Kapoor, about support for LTE-M and/or NB-IoT coverage in India, as he has more information about the local support for this. If you need his contact information, please let me know so I can make this ticket private and share it with you.

Best regards,

Marte
