PubSubClient with 2 clients

[mikeme2009]

Hi

I need to declare PubSubClient depending on a pin status. If status is 1 I will use PubSubClient mqttClient(ethClient), if pin= 0 PubSubClient mqttClient(wifiClient). How can I do that? I tried: WiFiClient wifiClient; EthernetClient ethClient; PubSubClient mqttClient(digitalRead(22) == 0 ? wifiClient : ethClient); - But error: no matching function for call to 'PubSubClient::PubSubClient(int)'

Thanks

You can se the setClient function to set which network client the library uses as part of the setup() function:

Something like this:

WiFiClient wifiClient;
EthernetClient ethClient;
PubSubClient mqttClient;

...

void setup() {
    if (digitalRead(22) == 0) {
        mqttClient.setClient(wifiClient);
    } else {
        mqttClient.setClient(ethClient);
    }
}
