Detailed Description

CoAP block transfer options encoding and decoding interface and definitions.

Macro Definition Documentation

#define COAP_BLOCK_OPT_BLOCK_MORE_BIT_SET 1

Value when more flag is not set.

#define COAP_BLOCK_OPT_BLOCK_MORE_BIT_UNSET 0

Value when more flag is set.

uint32_t coap_block_opt_block1_decode	(	coap_block_opt_block1_t *	p_opt,
		uint32_t	encoded
	)

Decode block1 option from a uint to its structure counter part.

Parameters

[out]	p_opt	Pointer to block1 option structure to be filled by the function. Must not be NULL.
[in]	encoded	Encoded version of the coap block1 option value.

Return values

NRF_SUCCESS	If decoding of the option was successful.
NRF_ERROR_NULL	If p_opt parameter is NULL.
NRF_ERROR_INVALID_PARAM	If the block number is higher then allowed by spec (more than 20 bits).
NRF_ERROR_INVALID_DATA	If the size has the value of the reserved 2048 value (7).

uint32_t coap_block_opt_block1_encode	(	uint32_t *	p_encoded,
		coap_block_opt_block1_t *	p_opt
	)

Encode block1 option into its uint binary counter part.

Parameters

[out]	p_encoded	Encoded version of the coap block1 option value. Must not be NULL.
[in]	p_opt	Pointer to block1 option structure to be decoded into uint format. Must not be NULL.

Return values

NRF_SUCCESS	If encoding of option was successful.
NRF_ERROR_NULL	If one of the parameters supplied is a null pointer.
NRF_ERROR_INVALID_PARAM	If one of the fields in the option structure has an illegal value.
