State Service

The state service is used for managing runtime persistent state, similar to the configuration service but specifically for storing runtime state information (such as battery capacity, cycle count, etc.).

State File Path​

#define EOS_STATE_FILE_PATH EOS_SYS_DIR "state.json"

Service Initialization​

void eos_service_state_init(void);

Boolean State​

eos_result_t eos_state_set_bool(const char *key, bool value);
bool eos_state_get_bool(const char *key, bool default_value);

String State​

eos_result_t eos_state_set_string(const char *key, const char *value);
char *eos_state_get_string(const char *key, const char *default_value);

The returned string needs to be freed using eos_free when no longer needed.

Number State​

eos_result_t eos_state_set_number(const char *key, double value);
double eos_state_get_number(const char *key, double default_value);
