Connection to Thinger

Hi,
How can you test for connection to Thinger in ESP32 Code. I am using WiFi_Connected == 1 before I initiate a thing.stream but sometimes WiFi is connected but Thinger is not, data is lost.

Thanks,

Try thing.is_connected()

thinger-io/Arduino-Library/blob/88a223864f8a7a3299f431b553824a328a49ef4b/src/ThingerClient.h#L500

      
        
                    if(available>0){
                        THINGER_DEBUG_VALUE("THINGER", "Available bytes: ", available);
                    }
                    #endif
                    thinger::thinger::handle(millis(), available>0);
                }else{
                    delay(RECONNECTION_TIMEOUT); // get some delay for a connection retry
                }
            }
            
            
bool is_connected(){
                th_synchronized(bool result = client_.connected();)
                return result;
            }
            
            
void set_credentials(const char* username, const char* device_id, const char* device_password){
                username_ = username;
                device_id_ = device_id;
                device_password_ = device_password;
            }

Thanks George, that is working.

I also have the problem that sometimes the servers for thinger are unreachable.
The consequence is that the thinger.handle() takes a long time (up to more than 1000ms).
That is massively disturbing my collaborative multitasking.
Could a wrapping with
if (thing.is_connected())
prevent that?

Hi,

I guess it won’t do anything, because the thing.handle(); instruction should be out of that “if” to get the client connected and get into the if.

Hope this helps.

Thank you. It’s what I feared.
