Cstruct aliro_uwb_msg_builder

Accumulates bytes into a heap-allocated Aliro UWB message.

message

Aliro UWB message under construction, holding encoded M1-M4 attributes and payload.

capacity

Capacity of the message buffer.

Fbool aliro_uwb_msg_builder_init(struct aliro_uwb_msg_builder *builder, uint16_t payload_len)

Allocate a message with room for payload_len payload bytes plus header.

Fvoid aliro_uwb_msg_builder_header(struct aliro_uwb_msg_builder *builder, uint8_t protocol, uint8_t id, uint16_t payload_length)

Append the 4-byte header (protocol, id, big-endian payload length).

Fbool aliro_uwb_msg_builder_add_u8(struct aliro_uwb_msg_builder *builder, uint8_t id, uint8_t value)

Append a 1-byte-value attribute.

Fbool aliro_uwb_msg_builder_add_u16(struct aliro_uwb_msg_builder *builder, uint8_t id, uint16_t value)

Append a 2-byte big-endian attribute.

Fbool aliro_uwb_msg_builder_add_u32(struct aliro_uwb_msg_builder *builder, uint8_t id, uint32_t value)

Append a 4-byte big-endian attribute.

Fbool aliro_uwb_msg_builder_add_u64(struct aliro_uwb_msg_builder *builder, uint8_t id, uint64_t value)

Append a 8-byte big-endian attribute.

Fbool aliro_uwb_msg_builder_add_u16_array(struct aliro_uwb_msg_builder *builder, uint8_t id, size_t count, const uint16_t *values)

Append an attribute whose value is count big-endian 16-bit words.

Fbool aliro_uwb_msg_builder_add_bytes(struct aliro_uwb_msg_builder *builder, uint8_t id, size_t count, const uint8_t *values)

Append an attribute whose value is count raw bytes.
