Function esp_idf_sys::ble_gap_encryption_initiate

pub unsafe extern "C" fn ble_gap_encryption_initiate(

Initiates the GAP encryption procedure as a master. This is for testing only and should not be used by application. Use ble_gap_security_initiate() instead.

@param conn_handle The handle corresponding to the connection to start encryption. @param key_size Encryption key size @param ltk Long Term Key to be used for encryption. @param udiv Encryption Diversifier for LTK @param rand_val Random Value for EDIV and LTK @param auth If LTK provided is authenticated.

@return 0 on success; BLE_HS_ENOTCONN if the there is no connection with the specified handle; BLE_HS_EALREADY if an encryption procedure for this connection is already in progress; Other nonzero on error.
