Thanks got Encoding working for the required JSON. Any pointers on how to get the decoding working ?
From the example https://github.com/apache/mynewt-core/blob/master/encoding/json/test/src/testcases/json_simple_decode.c <https://github.com/apache/mynewt-core/blob/master/encoding/json/test/src/testcases/json_simple_decode.c> Am able to decode upto name2 only. {“name1": 1,”name2": “value2”, “name3”: [{“name4”: 2, “name5”: 3}]}; Please let me know the Structure for Array of objects. struct json_attr_t test_attr[3] = { [0] = { .attribute = “name1", .type = t_integer, .addr.integer = &int_val, .nodefault = true }, [1] = { .attribute = “name2", .type = t_string, .addr.string = string1, .nodefault = true, .len = sizeof(string1) }, [2] = { .attribute = “name3", .type = t_array, .addr.array = { .element_type = t_integer, .arr.integers.store = intarr, .maxlen = sizeof intarr / sizeof intarr[0], .count = &array_count, }, .nodefault = true, .len = sizeof(intarr) }, [6] = { .attribute = NULL } }; > On 28-Feb-2018, at 2:05 PM, marko kiiskila <ma...@runtime.io> wrote: > > > >> On Feb 28, 2018, at 10:10 AM, Aditya Xavier <adityaxav...@me.com> wrote: >> >> Yes, that was derp from my end. >> >> Any clue on how to encode the JSON structure I mentioned ? >> >> Is this method correct ? > > You need to initialize the encoder; it needs to be told where to write > the encoded data.
