# CBOR Example ## Overview The [CBOR](https://en.wikipedia.org/wiki/CBOR)(Concise Binary Object Representation) is a binary data serialization format which is similar to JSON but with smaller footprint. This example will illustrate how to encode and decode CBOR data using the APIs provided by [tinycbor](https://github.com/intel/tinycbor). For detailed information about how CBOR encoding and decoding works, please refer to [REF7049](https://tools.ietf.org/html/rfc7049) or [cbor.io](http://cbor.io/); ## How to use example ### Hardware Required This example should be able to run on any commonly available ESP32 development board. ### Build and Flash Run `idf.py -p PORT flash monitor` to build and flash the project. (To exit the serial monitor, type ``Ctrl-]``.) See the [Getting Started Guide](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/index.html) for full steps to configure and use ESP-IDF to build projects. ## Example Output ```bash I (320) example: encoded buffer size 67 I (320) example: convert CBOR to JSON [{"chip":"esp32","unicore":false,"ip":[192,168,1,100]},3.1400001049041748,"simple(99)","2019-07-10 09:00:00+0000","undefined"] I (340) example: decode CBOR manually Array[ Map{ chip esp32 unicore false ip Array[ 192 168 1 100 ] } 3.14 simple(99) 2019-07-10 09:00:00+0000 undefined ] ``` ## Troubleshooting For more API usage, please refer to [tinycbor API](https://intel.github.io/tinycbor/current/).
