In the current state of the library, it does not make sense to have elements with bigger size than object builders. This should be checked on ardubsonConfig.h, just in the case the user changes it. Some errors and warnings could be prompted if the configuration is bizarre.

For the sake of completeness, embedded objects should be supported by the library.

This is a essential feature in JSON and BSON, since it allows to create a tree structure.

Could BSONObjBuilder have a collection of pointers referencing the elements it depends on instead of having a copy of them? This would greatly reduce the amount of memory needed by library objects, and would allow for some dynamic behaviors.

I suggest having a copy of the elements when they are appended using BSONObjBuilder::append(key, value), but using a pointer if BSONObjBuilder::append(BSONElement element) is used.

When I try to put the float value into the BSON object, after printing JSON I always get 0.0. Is there an example of a working float field inside BSON?

Code:

        BSONObjBuilder bob;
        BSONElement be;
        bob.append("1", (double)3.55);
        // Generate BSON Object
        BSONObject bo = bob.obj();

        // Get string object
        char *json = bo.jsonString();
        // Print BSON in JSON format
        Serial.print("JSON: ");
        Serial.println(json);

Result:

        JSON: {
            "1":0.000
        }
        Total Size of BSON raw data: 16
        BSON Element data (raw):
        0x10 0x00 0x00 0x00 0x01 0x31 0x00 0x00
        0x00 0x00 0xA0 0x33 0x33 0xE3 0xA5 0x00

Title says it all. If you would try to save mlre data it just gets cut off.

For the sake of completeness, arrays should be supported by the library.
