If CONFIG_ESPNOW_APP_SECURITY is enabled then ESPNOW_DATA_LEN defined as ESPNOW_SEC_PACKET_MAX_SIZE which is defined as (ESPNOW_PAYLOAD_LEN - TAG_LEN - IV_LEN), i.e. 218 bytes total.
Calling espnow_prov_initiator_send() gives error on
ret = espnow_send(ESPNOW_DATA_TYPE_PROV, responder_addr, prov_data,
sizeof(espnow_prov_data_t), &frame_head, portMAX_DELAY);
telling that data size is greater than ESPNOW_DATA_LEN (221 > 218)
