How to get the Device ID shown in the Programmer : About-Device section from AT commands?

eabase

Hi,

I'm connecting my Thingy:91 for the first time, and trying to understand several things.

1. How do I determine what factory Firmware files (hex files) was used to program my device?
(I was hoping to find them in the download section, but since I cannot find what was used to program the device, I don't know what to download.)

2. In the Programmer application there is section under the ABOUT tab, called Device. Here you can find the ID that is shown in all apps for the device. (See screenshot.)
(a) How can I find this ID, and where/how is it defined?
(b) Can we find it using AT commands?

Thanks in advance.

    Hello,

    1. How do I determine what factory Firmware files (hex files) was used to program my device?

    After downloading the firmware file of thingy:91, you can see a text file called CONTENTS.txt inside the folder which directs the use of hexfile. You can look at this Getting started with Thingy:91 — nRF Connect SDK 2.4.99 documentation (nordicsemi.com) getting started guide also.

    2. In the Programmer application there is section under the ABOUT tab, called Device. Here you can find the ID that is shown in all apps for the device. (See screenshot.)

    I do not think we can find this from AT command. You can find the device ID (https://infocenter.nordicsemi.com/topic/ps_nrf9160/ficr.html?cp=2_0_0_3_4_0_8#register.INFO.DEVICETYPE)from memory read command by using nrfjrpog.

    For example, this is my device ID when Thingy:91 is connected with external debugger (nRF9160).

    Thanks.

    Hi Kazi,

    Thanks for the info, but I am not able to run the program you suggest.
    Opening a Bash from nRF Connect for Desktop:

    It seem that there is a python package missing.
    No idea why, as it was installed by your installer.

    UPDATE:

    Apparently the installer did not install the "nRF-Command-Line-Tools".

    Now I get another error:

    Hello Emanuel,

    This is the way https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/working_with_nrf/nrf91/thingy91_gsg.html#id45 how you can update modem firmware on nRF9160. 

    You can see these file for specific applications and the description.

    You can program the hex file from programmer app or using nrfjprog. If we use nrfjprog then you have to use the external debugger and select the hex file (Open the folder img_app_bl that contains the HEX files for flashing with a debugger) from specific folder (img_app_bl).

    For example: I programmer asset trackerv2 on thingy:91 through command prompt using nrfjprog.

    Hi Kazi,

    This is an answer for a different question, not the one I had above.
    (I have already flashed the device and know how to do so.)

    Hello Emanuel,

    ''Thanks for the info, but I am not able to run the program you suggest.'' - could you please tell me that which program you are mentioning? I am sorry as my second reply did not satisfy your queries. 

    ''Apparently the installer did not install the "nRF-Command-Line-Tools".

    My operating system is windows and here is no problem to install nRF command line tools. I am not sure about this. I will ask our team will give you a feedback.

    Let me say again about device address a bit more again. I showed you to see the device ID for nRF9160 ( when the switch is  turned to nRF91). When it is nRF52840, we need to use the address for the register of that chip. for device.addr it is 0x10000064. nrfjprog --memrd command shows the following output.

    However, none of the IDs' are close to what we can see in the about tab in programmer app. I have found a code https://github.com/nrfconnect/sdk-nrf/blob/main/applications/connectivity_bridge/src/main.c that shows hoe device ID set in the application. So, it is clear that device ID is from deviceaddr register.

    I will ask the specific team about this ID on the programmer app. I am just curious why do you need this information?

    To Recap:

    For Q1 I was wondering how to determine from within the device what factory FW it was flashed with?
    (Perhaps there's an AT command that shows you the exact version?)

    For Q2, you referred me to use nrfjprog, but not saying that it requires a debugger attached, such as the nrF9160-DK (or other 3rd party). If there is another solution, for using that tool, please let me know.

    For example, can I use nrfjprog over USB interface if I flash the *debug version of the firmware?
    (I believe not..)

    References:
    Can the SWD port (P8) be used to collect Trace data using a serial-to-usb cable?


    > I am just curious why do you need this information?

    Because we are looking to get some kind of unique (but simple) ID that cannot be changed, and could be used for either the PSK keyid, deviceID or default PSK password, for provisioning devices to our test customers.
