Thanks Heidi

I did send you a request with the details. Can you confirm you have that?

Hi, yes you are correct. You can also see from the log that the nRF Connect identifies Model: NRF52840_xxAA_REV1, while when I connect my nRF91 DK to nRF Connect with the SW5 in the nRF91 position, it is identified as Model: NRF9160_xxAA_FUTURE.

I suspect there is a hardware issue on your board, relating to the SW5 not being able to reroute the debugger to the nRF9160.

If you send me a private message with your full name and postal address, we will send you a new kit.

Best regards,

Heidi

Using the 9160DK's jlink/Debug out I was able to loop the programmer back onto the board on the P3 (nrf91 Debug)

This allowed me to access the 9160 from NRF Connect and update its modem firmware and the Asset Tracker.

I repeated the process using the P11(nRF52 Debug in) and programmed the board FW hex file.

After reset I could connect via the USB to the LTE Link Monitor and using the second listed port access the modem via AT commands. It connected to LTE but was reseting repeatedly.

Next I logged into NRFCloud and requested a new cert using the boards imei Number and its Mac/HWID found on the sticker. This downloaded a JSON file that could then be used to update the modems certificates.

The board was powered off and the sim removed. Opened the LTE Link Monitor powered on the 9160DK and could see it boot in the console. Next step was to use the AT commands to make sure it was working and to shut off the cell modem with AT+CFUN=4.

Updated the certificate and reset - 60 sec later it was connected !!

After that it was a simple matter of adding the device to the NRFCloud and making sure that it was added using the imei and MAC/HWID used to make the certificate.

I now have a fully updated nRF9160DK that is attached to the nRFCloud.

Remaining questions...

According to the documentation all of this should be able to be achieved using just the USB connection. NRF Connect still only allows the erasing and programming of the nRF52 even though it sees all three usb ports...

When this device is selected it reports ...

It's not seeing a NRF9160 and hence the modem firmware update is greyed out.

I have been using the latest board Firmware in the 52840 and the latest modem firmware(1.1.0) and asset tracker in the 9160.

The nRF9160DK is Rev 0.9.0 and NRF Connect is version 3.3.0.

At this point the only way I can access the 9160 is to use the loop method from above.

Have you tried moving the switch?

The switch is set to nrf91

Is there any chance that SW5 on the DK is switched to the left (nRF52) instead of to the right (nRF91)?

Heidi,

In both Mac and Windows versions of Programmer when I select that board (PCA10090) the "Update Modem" is greyed out. I downloaded the pre-built Asset_tracker and programmed it with the same results. This is the asset_tracker I used..

Thanks in advance...

Hi!

In Programmer, if you select the board (PCA10090), then the "Update modem" button should be activated and you can add the .zip file and update the modem firmware. Please let me know if this doesn't work.

In LTE Link Monitor, in the bottom right select "Auto device/port filter" to only get one device, the DK. If nothing comes up, even after hitting the reset button on the DK, the firmware you're running doesn't work. Are you running the latest asset_tracker firmware, found in NCS tag v1.1?

Best regards,

Heidi
