Unable to upload working compiled hex file to Thingy91

[NautDesigner]

If I upload the pre-compiled asset_tracker file to the Thingy91, it works fine. If I compile it myself and try to upload it, nothing happens. It shows the write is successful but nothing happens. I've tried compiling in SES and via the command line (west build -b thingy91_nrf9160ns). I've tried uploading each of the following hex files but none work:

app_signed.hex
mcuboot_primary.hex
mcuboot_primary_app.hex
merged.hex

Uploads are being done using the nRF Connect v3.6.1 Programmer. I'm using v1.4.1 packages.

I've tried several other sample programs with the same results.

Hello, 

Can you please be more specific in what "nothing happens" mean? What do you get from the output (COM port) of the device? Please install the LTE Link Monitor in nRF Connect for Desktop, and see what the output gives. Have you updated the modem FW?

Edit: Please make sure to follow our instructions provided in "Programming the Thingy:91", and read the documentation on "Working with Thingy:91".

Kind regards,
Øyvind

I was able to get the firmware to upload and I do see data in the LTE Link Monitor. However, I do not see any output with a serial terminal connected to either port. I'm connecting at 115200, N, 8, 1. I tried with and without CTS flow control.

Can you please share a complete screenshot of the LTE Link Monitor? The LTE Link Monitor is a serial terminal and will automatically connect the correct COM port if "Auto device/port filter" is checked/enabled.

Your device is working as intended. Please see LTE Link Monitor.

Kind regards,

Yes. But is there a way to monitor it with just terminal software? Compiling the Zephyr basic programs, I see no output.

Hi, 

I'm sorry, but your last question is out of scope of your original question. Can you please submit a new ticket with correct topic? 

Thank you!

Kind regards,
