HTTP FOTA Update

[mschweig]

Hi, 

I am currently trying to set up the HTTP Application Update Sample and unfortunately it keeps stopping at the "downloading" state. Code is exactly the same from the latest nrf samples.

I am connected to the network and the update.bin file can be accessed via the browser. 

Please see the screenshot of the output:

After about 15 Minutes I recieve a download client error:

Does anyone have hints? 

Kind regards and thanks in advance, 

Manuel

Hi Manuel,

Very sorry for the delayed response. I have tested both on NCS v1.0.0 & the latest master branch. The latest master branch from this morning seems to be stable. I did not receive a download client error & the app worked like stated in the documentation.

You are referring to the latest master branch, correct?

Hi Bjorn, 

thanks for your answer. No I am using v1.0.0 currently. I guess there is no problem with the lte connection, bc the mqtt connection works fine for example.

In general, unless you require new functionality, it is always recommended to use the latest tagged release of NCS. The latest master branch could be unstable, as developers are constantly coming up with new features (and introducing new bugs too unfortunately)

Hi Bjorn, 

sorry I edited the answer too late. I am using tagged v1.0.0 at the moment.

I just tried again with v1.0.0 using a v0.8.5 DK & everything worked fine on LTE-M1. There may be something with the LTE network maybe? I cannot reproduce your error unfortunately.

Okay thanks for the info - I am on NB-IoT, I will try to get some network traces. One other question: 

When I call sys_reboot() the system halts and there is no more output on the console, but the reboot is not carried out. CONFIG_REBOOT is set to "y" in prj.conf.
Can you help me with that? 

Kind regards,

manuel

Yeah, sorry about that. I will try again with nB soon & get back to you. Regarding your other question, I am not too sure. Does nrfjprog -r work in that case? I see there is also an option for a cold reboot:

Have you tried that?

[mschweig]

Yeah, I also tried it with 0,1, SYS_REBOOT_WARM and SYS_REBOOT_COLD. Also tried it just by placing it to main without anything or using a work handler. Nothing worked out.

Hi, regarding the sys_reboot(): I solved the problem by reflashing the SPM (without any change in the code). Now it works.
