# ESPMQTT Emitter client
## Before you run this Example
- Register an account from https://emitter.io/
- Login and create channel key, grant access for the channel `/topic/` as the images bellow
- `make menuconfig` provide Wi-Fi information and CHANNEL_KEY to `MQTT Application example`
- `make flash monitor`

# ESPMQTT SSL Sample application
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.
