(See the README.md file in the upper level 'examples' directory for more information about examples.)
Main purpose of this example is to test the MQTT library to correctly publish and receive messages (of different size and sequences) over different transports.
It is possible to run this example manually without any test to exercise how the MQTT library deals with
- reception of fragmented messages
- runtime updates of URI
## How to use example
This example waits for user input to provide these parameters:
- transport: string parameter, one of: tcp, ssl, ws, wss
- pattern: sample string to be transmitted as message
- pattern repeats: number of repeats of pattern in one MQTT message
- repeated: number of repeats ESP32 publishes the message, also ESP32 expects to receive the same message the same number of repeats
- qos: number specifying qos, one of: 0, 1, 2
### Hardware Required
This example can be executed on any ESP32 board, the only required interface is WiFi and connection to internet.
* Run `make menuconfig` (or `idf.py menuconfig` if using CMake build system)
* Configure Wi-Fi or Ethernet under "Example Connection Configuration" menu. See "Establishing Wi-Fi or Ethernet Connection" section in [examples/protocols/README.md](../../README.md) for more details.
* When using Make build system, set `Default serial port` under `Serial flasher config`.
