# ESP-MQTT SSL Sample application (mutual authentication)
|
||||
|
||||
(See the README.md file in the upper level 'examples' directory for more information about examples.)
|
||||
|
||||
This example connects to the broker test.mosquitto.org using ssl transport with client certificate and as a demonstration subscribes/unsubscribes and send a message on certain topic.
|
||||
(Please note that the public broker is maintained by the community so may not be always available, for details please visit http://test.mosquitto.org)
|
||||
|
||||
It uses ESP-MQTT library which implements mqtt client to connect to mqtt broker.
|
||||
|
||||
## How to use example
|
||||
|
||||
### Hardware Required
|
||||
|
||||
This example can be executed on any ESP32 board, the only required interface is WiFi and connection to internet.
|
||||
|
||||
### Configure the project
|
||||
|
||||
* Open the project configuration menu (`idf.py menuconfig`)
|
||||
* 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`.
|
||||
|
||||
* Generate your client keys and certificate
|
||||
|
||||
Navigate to the main directory
|
||||
|
||||
```
|
||||
cd main
|
||||
```
|
||||
|
||||
Generate a client key and a CSR. When you are generating the CSR, do not use the default values. At a minimum, the CSR must include the Country, Organisation and Common Name fields.
|
||||
|
||||
```
|
||||
openssl genrsa -out client.key
|
||||
openssl req -out client.csr -key client.key -new
|
||||
```
|
||||
|
||||
Paste the generated CSR in the [Mosquitto test certificate signer](https://test.mosquitto.org/ssl/index.php), click Submit and copy the downloaded `client.crt` in the `main` directory.
|
||||
|
||||
Please note, that the supplied files `client.crt` and `client.key` in the `main` directory are only placeholders for your client certificate and key (i.e. the example "as is" would compile but would not connect to the broker)
|
||||
|
||||
### Build and Flash
|
||||
|
||||
Build the project and flash it to the board, then run monitor tool to view serial output:
|
||||
|
||||
```
|
||||
idf.py -p PORT flash monitor
|
||||
```
|
||||
|
||||
(To exit the serial monitor, type ``Ctrl-]``.)
|
||||
|
||||
See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
|
||||
|
||||
