## Adjust your settings:
* Adjust the broker to the address you want to use: `broker_source`
* Add your custom filters to `filterMessage()` if you want to filter messages
* Adjust your credentials (uncomment if anonymous):
```python
client_source.username_pw_set("mqtt", "IoT")
```
* Adjust your MySQL credentials:
```python
DatabaseHostName = 'YourHost'
DatabaseUserName = 'YourUser'
DatabasePassword = 'YourPassword'
DatabasePort = 3306
```
* Run the script `SetupDatabase.sql` on your database to setup the database correctly
* Add filters to the bridging like described in the `bridgeFiltering.py` file if needed:
```python
def filterMessage(payload, topic, qos):
"Filters the messages depending on the configuration for the attributes payload, topic and QoS. 'True' means that the message is not forwarded."
# Examples below:
if(payload == "10 %"):
print('Filtered: payload == "10 %"')
return True
if(topic == "humidity" and qos == 0):
print('Filtered: topic == "humidity" and qos == 0')
return True
if(topic == "temperature" or qos == 2):
print('Filtered: topic == "temperature" or qos == 2')
return True
#Add your filters here
```
## Setup on the Raspberry Pi
```bash
sudo apt-get install python3
sudo apt-get install python3-pip
sudo pip3 install paho-mqtt
sudo pip3 install pymysql
```
or
```bash
sudo apt-get install python3
sudo apt-get install python3-pip
sudo pip3 install -r requirements.txt
```
## Running the programms:
```bash
python3 bridge.py
python3 bridgeFiltering.py
```
