Can sec_tag be generated during runtime?

[flau]

I tried generating sec_tag using sys_rand32_get() or other arithmetic method during runtime.  All 3 certificates (CA, client cert, client key) were able to be written into the nRF9160.  But when I tried to use them to connect with AWS, it always failed.  These were the messages.

W: connection_poll_start failed, error: -119
aws_iot_connect, error: -119
Next connection retry in 30 seconds
AWS_IOT_EVT_DISCONNECTED

However, if I hardcoded a sec_tag in the firmware using

#define sec_tag 123456,

then it worked.  Does sec_tag have to be pre-defined before building the code?  Thank you.

Hello,

Does sec_tag have to be pre-defined before building the code?

I asked the developer directly and the answer is that it is not possible to choose the sec tag at run time.

Got it.  Thank you, Hakon.
