Detailed Description

data service message structure type

Field Documentation

body

uint8_t data_msg_t::body[(12)]

Saving whole short msg body, which length <= SHORT_DATA_MSG_BODY_THRESHOLD. For long msg body which length > SHORT_DATA_MSG_BODY_THRESHOLD, we'll allocate a memroy from heap and save a pointer here.

len

uint16_t data_msg_t::len

Parameter length

msg_id

uint16_t data_msg_t::msg_id

Message ID, see MSG_SERVICE_XXX

no_free

uint32_t data_msg_t::no_free

1: no need to free memory of long msg, 0: need to free memory of long msg
