2. Dual banker:AB partition upgrade to support rollback to old version;
3. Secure download channel;
4. Firmware digital signature verification.

Dependencies

Linkkit MQTT channel Linkkit CoAP channel

API

User service APIs:

typedef struct {
    unsigned char  inited;  /*If is inted*/
    char  pk[20+1];/*Product Key*/
    char  ps[64+1];/*Product secret*/
    char  dn[32+1];/*Device name*/
    char  ds[64+1];/*Device secret*/
    OTA_PROTCOL_E  trans_protcol;  /*default:0--> MQTT 1-->COAP*/
    OTA_PROTCOL_E  dl_protcol;     /*default:3--> HTTPS 1-->COAP 2-->HTTP*/
    unsigned char  sign_type;      /*default:0--> sha256 1--> md5 2-->RSA*/
    char           ota_ver[OTA_MAX_VER_LEN];  /*OTA FW version*/
    char           sys_ver[OTA_MAX_VER_LEN];  /*OTA System version*/
    ota_transport_t *h_tr;    /*OTA tansport manager*/
    ota_download_t  *h_dl;    /*OTA download manager*/
    void*    h_ch;            /*OTA channel handle:mqtt,coap*/
} ota_service_t;

/*OTA export service APIs*/
int ota_service_init(ota_service_t* ctx);
int ota_service_deinit(ota_service_t* ctx);
