Json: How to encode an array of objects

[c4explosive]

I need to encode an array of objects like this:
[{"number":5 ,"text":"aaaaaa" ,"no_used":0},{" number":8,"text" :"eeeee","no_use d":0},{"number": 7,"text":"iiiiii ","no_used":0}]

but when i use this macro: JSON_OBJ_DESCR_OBJ_ARRAY

Produce something like this:

{"simple _s":[{"number":5 ,"text":"aaaaaa" ,"no_used":0},{" number":8,"text" :"eeeee","no_use d":0},{"number": 7,"text":"iiiiii ","no_used":0}]}

¿How can i encode this array without the additional object: "simple_s"?.

My json description structure code is like this:

struct simple_struct {
    int number;
    const char* text;
    int no_used; //This variable is part of object
};
struct nested_simple {
    struct simple_struct simple_s[10];
    size_t simple_s_len;
};
static const struct json_obj_descr simple_json_descr[] = {
    JSON_OBJ_DESCR_PRIM(struct simple_struct, number, JSON_TOK_NUMBER),
    JSON_OBJ_DESCR_PRIM(struct simple_struct, text, JSON_TOK_STRING),
    JSON_OBJ_DESCR_PRIM(struct simple_struct, no_used, JSON_TOK_NUMBER),
};
static struct json_obj_descr array[] = {
    JSON_OBJ_DESCR_OBJ_ARRAY(struct nested_simple, simple_s, 10,
        simple_s_len, simple_json_descr, ARRAY_SIZE(simple_json_descr)),
};

My bad, i used this function: json_obj_encode_buf instead of json_arr_encode_buf. The first is for encode objects, so generate this output:

{"simple _s":[{"number":5 ,"text":"aaaaaa" ,"no_used":0},{" number":8,"text" :"eeeee","no_use d":0},{"number": 7,"text":"iiiiii ","no_used":0}]}

But the second (json_arr_encode_buf) generates an array, so the encoded output is like this:

[{"number":5 ,"text":"aaaaaa" ,"no_used":0},{" number":8,"text" :"eeeee","no_use d":0},{"number": 7,"text":"iiiiii ","no_used":0}]
