How do I read and write the IMEI number with 9160?

[duxinglang]

As we know, NRF9160 supports NB network and has an IMEI number itself. Now I want to know whether I can manage this IMEI number, such as reading, writing or modifying.In nrf9160 development and production of a product, each device will have a belongs to own IMEI number, in general, this IMEI will be ready before production, and printed on the label, when the product before delivery, the IMEI label on the box, and put the IMEI number write in the packaging of the product, the Nordic official offer such interfaces, or batch write IMEI tool?

Hi Duxingland,
IMEI number is readable for the nrf9160, but cannot be modified.

it can be read out by e.g. the AT command AT+CGSN

Just follow the instructions here

Therefore, there is a problem. When we use nrf9160 to mass produce products, how can I get the IMEI number of each product and display it on the box? It is obviously unreasonable to read IMEI number by manual instruction of a product by product through at command.

In our kit production, there is a test firmware that reads out the IMEI and sends that to a test PC which writes out a label which is then attached to the box and the kit.

(Also attaching the Production Programming application note).

Hi Martin, are you willing to share this test firmware / source code that does exactly what you mentioned below?  We also are trying to do the exact same thing to print the label / box kit.

Hi Arthur,
I assume you already have some kind of production test in place (see link), or at least you should have in the future.
It should be rather simple to incorporate one step where you read out the IMEI and then print that number out.
