Detailed Description
OMA LWM2M object TLV encoder and decoder API.
Function Documentation
| uint32_t lwm2m_tlv_security_decode | ( | lwm2m_security_t * | p_security , |
| uint8_t * | p_buffer , | ||
| uint32_t | buffer_len | ||
| ) |
Decode a LWM2M security object from a TLV byte buffer.
- Note
- Resource values NOT found in the tlv will not be altered.
- Warning
- lwm2m_string_t and lwm2m_opaque_t values will point to the byte buffer and needs to be copied by the application before the byte buffer is freed.
- Parameters
-
[out] p_security Pointer to a LWM2M server object to be filled by the decoded TLVs. [in] p_buffer Pointer to the TLV byte buffer to be decoded. [in] buffer_len Size of the buffer to be decoded.
- Return values
-
NRF_SUCCESS If decoding was successful.

| lwm2m_security_t * | p_security | ||
| ) |
Encode a LWM2M security object to a TLV byte buffer.
- Parameters
-
[out] p_buffer Pointer to a byte buffer to be used to fill the encoded TLVs. [in,out] p_buffer_len Value by reference indicating the size of the buffer provided. Will return the number of used bytes on return. [in] p_security Pointer to the LWM2M security object to be encoded into TLVs.
- Return values
-
NRF_SUCCESS If the encoded was successful.

- Warning
- lwm2m_string_t and lwm2m_opaque_t values will point to the byte buffer and needs to be copied by the application before the byte buffer is freed.
- Parameters
-
[out] p_server Pointer to a LWM2M server object to be filled by the decoded TLVs. [in] p_buffer Pointer to the TLV byte buffer to be decoded. [in] buffer_len Size of the buffer to be decoded.
- Return values
-
NRF_SUCCESS If decoding was successful.

| ) |
Encode a LWM2M server object to a TLV byte buffer.
- Parameters
-
[out] p_buffer Pointer to a byte buffer to be used to fill the encoded TLVs. [in,out] p_buffer_len Value by reference indicating the size of the buffer provided. Will return the number of used bytes on return. [in] p_server Pointer to the LWM2M server object to be encoded into TLVs.
- Return values
-
NRF_SUCCESS If the encoded was successful.
