Wait. Here is the entire output:

%KEYGEN:"MIIBCTCBrwIBADAvMS0wKwYDVQQDDCQ1MDRiNTgzOS0zNzM1LTRkNzEtODA2OC0xNDE2NGM3NGE0NGQwWTATBgcqhkjOPQIBBggqhkjOPQMBBwNCAATlKIQdFYs4sUZy4BW6Zcvsge2lzKha2LMiW-lNM4dFbfedPIk6v-oFLjgRdquYuW_go0sdAHYeFbW2kLRUIKEToB4wHAYJKoZIhvcNAQkOMQ8wDTALBgNVHQ8EBAMCA-gwDAYIKoZIzj0EAwIFAANHADBEAiA9xlIJW0l25i9pM3OxTOWQVy5fV2rGDsKkMwCsLWD3TwIgGBmmdumjX6jWe5kmLUgx7T2-u4sgvaLu4KVkWoCYWFc.0oRDoQEmoQRBIVhL2dn3hQlQUEtYOTc1TXGAaBQWTHSkTUELWCBhM5caHRDBXSsuyOhyX_ovdeibUKQ-xognwA-uWTUWnFAV_0IlB1Kb3Ia_38b93rflWEDxBkoNJeJNlAZTZdCETVBOKLWxDuKt-J3CuW17rUWsEuvRiArHUzgsNyBRepuXm7ITslxOw3CtwWuoDjh64gB6"

I can see a dot about 2/3 down the string, Fc.0o. Is what I am getting correct?

I am running mfw v1.3.4. I tried to do the same thing with at%keygen=11,2,0. The output shows the entire key. It doesn't look like a CBOR format "xxxxxxxx.xxxxxxx" at all. It also writes the key into sec tag 11. Did I miss something?

Hi,

Are you certain that you're using mfw v1.3.1 on the device you're testing with?

You will need to run this sequence with mfw v1.3.x branch.

I tested the serial_lte_modem, without any changes at all (I kept "CONFIG_AT_MONITOR_HEAP_SIZE" to default 256 size), and this was the output after issuing the AT command:

AT%KEYGEN=16842753,2,0

%KEYGEN: "MIIBCTC..redacted_key"

Have you tried to issue the same with the "at_client" sample instead?

Kind regards,

Håkon
