Connection Error #24

Closed DavidMR91 closed 2 years ago

DavidMR91 commented 2 years ago

Hello, when this line:

LOG_PRINTFLN("Connection error: %i", rc);

is rturning: Connection error: %i-5 or Connection error: %i-6

what do these errors mean? What is the meaning of the other numbers it can return?

It just prints the value of the rc. I assume you are about the rc of the connect call: Error::type connect(const MQTTPacket_connectData& connectOptions, ConnectResult& result) call.

See enum for all possible Error::type values: MqttClient.h#L200 See the connect implementation to find more details: MqttClient.h#L469

In your case:

WAIT_TIMEOUT = -6,
NETWORK_FAILURE = -5
