adityaxavier opened a new issue #1330: CBOR Decoding of Array of Arrays not working
URL: https://github.com/apache/mynewt-core/issues/1330
 
 
   Hi,
   CBOR Decoding for an Array of Int Array for e.g. 
   the following structure :-
    {a:[1,2,3,4], b:[ {c:[1,2,3,4,5]}, {c:[1,2,3,4,5]}]}
   
   Tried decoding using the following structure.
   
   uint64_t a[5];
   Int a_count = 0;
   
   struct c_object{
   	int c[6];
   }c_arr_objs[5];
   int c_obj_count = 0;
   
   struct cbor_attr_t c_attrs[] = {
      {
          .attribute = “c",
          .type = CborAttrObjectType,
          CBORATTR_STRUCT_OBJECT(struct c_object, c),
          .dflt.integer = 0
      },
      {
          .attribute = NULL
      }
   };
   // Tried CborAttrObjectType, CborAttrIntegerType and CborAttrArrayType.
   
   struct cbor_attr_t root_attrs[] = {
      {
          .attribute = “a",
          .type = CborAttrArrayType,
          .addr.array.element_type = CborAttrUnsignedIntegerType,
          .addr.array.arr.uintegers.store = a,
          .addr.array.count = &a_count,
          .addr.array.maxlen = sizeof(a) / sizeof(a[0]),
          .nodefault = true
      },
      {
          .attribute = “b",
          .type = CborAttrArrayType,
          CBORATTR_STRUCT_ARRAY(c_arr_objs, c_attrs, &c_obj_count),
          .nodefault = true
      },
      {
          .attribute = NULL
      }
   };
   
   This method doesn't work. The method is very similar to the example given in the following test case :-
   cborattr/test/src/testcases/cborattr_decode_int_array.c
   
   Please let me know if there is a mistake on my end.
