I have run into some problems while updating to the new firmware. When I try to get NCS v.1.0.0 I get the following output:

fatal: unable to access 'github.com/.../': SSL certificate problem: self signed certificate in certificate chain

How can I fix this?

Kind regards

Samuel

- Please make sure you have the latest mfw version on the kit first.

- Then you could erase all from the application flash to make sure you don't have garbage data.

- Then flash the at_client sample

(adding the precompiled at_client sample devzone.nordicsemi.com/.../3884.merged.hex)

You can use the "Programmer app" in nRF Connect for Desktop to flash the application.

Martin Lesund could you please upload pre-compiled at_client firmware for testing. I get the following error when I try to compile the sample and upload it.

So, when i try to write the file, it seems to freeze nRFConnect. I did update to 3.0.0 and when I go to open the v1.0.0 zip file it freezes the program and I have to exit the program in order to do anything

Hi Octvargas,

The v1.0.0 of the modem firmware was just released as well as NCS v1.0.0!

Please get NCS v1.0.0 with:

cd ncs/nrf
git checkout master
git pull
git checkout v1.0.0
west update

There is a new way to do modem DFU with version v1.0.0 of the mfw:

- Update to the latest 'nrfjprog'. (download link)

- Download mfw v1.0.0

- Update to nRF Connect for Desktop to v3.0.0

- Make sure you have the latest version of the "Programmer" app:

- Open the "Programmer" app

- Select device

- Select "Update Modem"

- Find the .zip folder 'mfw_nrf9160_1.0.0.zip' and select it:

- Hit the "Write" button

Now the Modem DFU procedure should start and you should get the newest modem firmware.

You can confirm this by running the at_client sample in combination with "LTE Link Monitor" and sending the AT command:

AT+CGMR

Note that there is also released a new SES IDE version (v4.18) with several updates.

Please find the newest version from the download link in the "Getting Started Assistant" app:

Best Regards,

Martin L.

Yeah, that was brought to my attention by Martin, but it still seems to spit out the same error

I can see from the images that you are running these commands in different folders, the first time in "C:\Users\recor\Documents\Modem Update" and the second time in "C:\Users\recor". I believe you need to run the command in the same folder as nrf9160_mdm_dfu-0.10.0+dev-py3-none-any.whl is located.

Hi Martin,

Thanks for your input. So I've tried

and I've also tried

both to no avail. Do you have any other suggestions?

Hi Octvargas,
Please confirm that you are in the correct folder:

Also please try pip3 if regular 'pip' does not work.

Thanks for the suggestion! However...

I tried the new filename, seem to still be getting the same error.

I made the same error yesterday. The line you copied from the README contains "nrf9160_mdm_dfu-0.10.1.....", but the .WHL file has "...-0.10.0...."

Entering "pip install nrf9160_mdm_dfu-0.10.0+dev-py3-none-any.whl" should work.

I hope this helps
