I'm having trouble figuring what hex to use to update to my card

[charlestonmike]

I'm having trouble figuring what hex update to flash to my card. I downloaded and unzipped the nrf9160dk_fw_2024-03-13_af2b60d2 file. I opened up the "Programmer" in nRF  connect tool. I connected to my device and then clicked the "add file" and pointed the 4.3.0 version program tool to the zip file and then clicked "write". 

Now I'm trying to update my application firmware so I click on the "add file" once again but when I go to the "img_app_bl" folder to flash the update there are a bunch of unclear options. What hex do I use to flash my card? According to the iBasis map I live in an area that only supports "LTE-M" (the United States). 

I wish the hex files were a little clearer

Thank you in advance for any help with this!

Hi Mike

Thank you for contacting DevZone at NordicSemi.

In the img_app_bl folder, there are 6 hex files. These hex files are for different applications. These applications are:
Asset Tracker V2
AT Client
Modem Shell
NRFCloud Multi service
and Serial LTE Modem
which application you want to flash on the DK?
Also, note that only the Asset Tracker application has two hex files, one for the LTEM and the other for the NBIOT.
So if you plan to use/try the Asset Tracker, then chose the first file as that should work for the LTEM.

Regards,
