Detailed Description

Expected usage of configuration interface:

struct ubx_msg_cfg_valset_v0 *valset;
NET_BUF_SIMPLE_DEFINE(cfg_buf, 32);
 
ubx_msg_prepare_valset(&cfg_buf, UBX_MSG_CFG_VALSET_LAYERS_RAM | UBX_MSG_CFG_VALSET_LAYERS_BBR);
UBX_CFG_VALUE_APPEND(&cfg_buf, UBX_CFG_KEY_RATE_MEAS, fix_interval_ms);
UBX_CFG_VALUE_APPEND(&cfg_buf, UBX_CFG_KEY_RATE_NAV, 1);
ubx_msg_finalise(&cfg_buf);

Macro Definition Documentation

UBX_CFG_VALUE_APPEND

#define UBX_CFG_VALUE_APPEND	(		buf,
			key,
			value )

#include </__w/infuse-sdk/infuse-sdk/infuse-sdk/include/infuse/gnss/ubx/cfg.h>

Value:

        do {                                                                                       \
                net_buf_simple_add_le32(buf, key);                                                 \
                _UBX_CFG_VALUE_APPEND_FN(((key) & _UBX_CFG_KEY_SIZE_MASK))(buf, value);            \
        } while (0)

Macro to append a configuration value to a buffer.

Implemented as a macro to allow the type of value to be preserved. As key should always be a compile time constant, only the chosen branch should ever be present in the output binary.

Parameters

buf	Buffer to append value to
key	UBX configuration value key
value	Value

Function Documentation

ubx_cfg_val_parse()

int ubx_cfg_val_parse ( const uint8_t ** ptr, size_t * remaining, struct ubx_cfg_val * cfg )

inlinestatic

#include </__w/infuse-sdk/infuse-sdk/infuse-sdk/include/infuse/gnss/ubx/cfg.h>

Iteratively parse configuration values from a buffer.

Expected usage:

struct ubx_cfg_val cfg_val;
uint8_t *val_ptr = &buffer;
uint16_t val_len = buffer_len;
 
while (ubx_cfg_val_parse(&val_ptr, &val_len, &cfg_val) == 0) {
    Handle cfg_val here...
}

Parameters

ptr	Pointer to configuration buffer to parse
remaining
cfg

Returns

int
