nrf9160 feather running Nordic Asset Tracker V2 program

Hi, I’ve been playing around with the 9160 feather and have had the AT commands program running. then I managed to get the AWS-iot sample connected to my aw...

I have been able to connect to the Golioth cloud servers even if it says the PSK and PSK_ID is incorrect. I think it might be using different values for checking than the actual crdentials.

@cwb the sample requires you load the appropriate PSK and PSK ID to the device secure key store. Did you do that? Also when it is loaded there you can safely ignore the messages about PSK being invalid.

https://github.com/circuitdojo/nrf9160-feather-examples-and-drivers/tree/v2.4.x/samples/tracker#update-credentials-in-modem-one-time-only

Also you’re likely running on an old version of the modem firmware which is not compatible with 2.4.x. You’ll need to update it so it will work with your board.

Also the tracker firmware uses AT shell now. so you’ll need to prepend any AT commands with at

Ex:

at AT
at AT+CFUN=1

You will need to escape the % character if you use a command that utilizes it by typing two %%:

at AT%%CMNG

Thanks guys,

I followed the procedure for uploading the PSK so i will ignore that for now.

I’ll try the firmware upgrade. I am getting an error running the upgrade so will look at that in a couple of days when I’m back. interesting when I go to nRF programmer it won’t read the memory, I thought it was because it was a sparkfun board but now that the python script won’t work it might not be.

Reading the memory requires an external programmer. You can upgrade the MFW with that as well if you have one.

External programmer:
https://docs.circuitdojo.com/nrf9160-programming-and-debugging.html#requirements-for-external-programming-and-debugging

Updating MFW with external programmer:
https://docs.circuitdojo.com/nrf9160-managing-mfw.html#modem-firmware-update-with-nrfjprog

Note: you don’t need the Tag Connect cable for the Thing Plus variant.

Thanks Jared,

i’ll start running through some troubleshooting on the external programing now.

going through those instructions you sent I run into some errors with jlink.
