Hi, you can take a look at the explanation of SEC_ENCRYPT and SEC_ENCRYPT_NO_MITM in this file (
https://github.com/espressif/esp-idf/bl ... _ble_api.h). In fact, MITM can be understood as requiring human participation in practice, such as entering a password and comparing the pairing code; if the default password is used for encryption and pairing (JUST WORK ) method, there is no way to prevent MITM attacks
