MbedTLS Server connection with client using SE052

MohitGediya — Fri, 22 May 2026 12:18:38 GMT

Hardware setup:
Board SoC: ESP32C3devkitm board and IC is SE052F2HN2Z019HJ.

Now i use nano plug and trust module's "se05x_mbedtls_alt_test" example.
Flash in board. But i face issue to verify "plugandtrust: Error in mbedtls_pk_verify. ret = -19968".

I change both key as per document of SE052. In my code.

Here is full sample application. Please verify it and suggest me the change that i need to fix.
Also give valid informative document about this so, i can explore more features of it.
And also,
I want to create TCP zephyr server based sample application. for that what informations i can store inside SE052 IC(this ic)? Which is use for cryptographic operation.
Which api and steps i need to follow to send encrypted data to client and client will decrypt the data.(client is other same setup board).
Which type of algorithm should i use for mbedTLS.

Hi @MohitGediya ,

Is it possible to have the APDU log out of the test when you run "se05x_mbedtls_alt_test" example?

Have a great day,
Kan
