Function Documentation

◆ OTA_CBOR_Decode_GetStreamResponseMessage()

bool OTA_CBOR_Decode_GetStreamResponseMessage ( const uint8_t *  pMessageBuffer,
size_t  messageSize,
int32_t *  pFileId,
int32_t *  pBlockId,
int32_t *  pBlockSize,
uint8_t *const *  pPayload,
size_t *  pPayloadSize 
)

Decode a Get Stream response message from AWS IoT OTA.

Parameters
[in]pMessageBuffermessage to decode.
[in]messageSizesize of the message to decode.
[out]pFileIdDecoded file id value.
[out]pBlockIdDecoded block id value.
[out]pBlockSizeDecoded block size value.
[out]pPayloadBuffer for the decoded payload.
[in,out]pPayloadSizemaximum size of the buffer as in and actual payload size for the decoded payload as out.
Returns
TRUE when success, otherwise FALSE.

◆ OTA_CBOR_Encode_GetStreamRequestMessage()

bool OTA_CBOR_Encode_GetStreamRequestMessage ( uint8_t *  pMessageBuffer,
size_t  messageBufferSize,
size_t *  pEncodedMessageSize,
const char *  pClientToken,
int32_t  fileId,
int32_t  blockSize,
int32_t  blockOffset,
const uint8_t *  pBlockBitmap,
size_t  blockBitmapSize,
int32_t  numOfBlocksRequested 
)

Create an encoded Get Stream Request message for the AWS IoT OTA service. The service allows block count or block bitmap to be requested, but not both.

Parameters
[in,out]pMessageBufferBuffer to store the encoded message.
[in]messageBufferSizeSize of the buffer to store the encoded message.
[out]pEncodedMessageSizeSize of the final encoded message.
[in]pClientTokenClient token in the encoded message.
[in]fileIdValue of file id in the encoded message.
[in]blockSizeValue of block size in the encoded message.
[in]blockOffsetValue of block offset in the encoded message.
[in]pBlockBitmapbitmap in the encoded message.
[in]blockBitmapSizeSize of the provided bitmap buffer.
[in]numOfBlocksRequestednumber of blocks to request in the encoded message.
Returns
TRUE when success, otherwise FALSE.
