void begin(Logger& baseLogger, Client* inClient, const char* registrationToken, const char* samplingFeatureUUID)
Begin the publisher - linking it to the client and logger.
Parameters | |
---|---|
baseLogger | The logger supplying the data to be published |
inClient | An Arduino client instance to use to print data to. Allows the use of any type of client and multiple clients tied to a single TinyGSM modem instance |
registrationToken | The registration token for the site on the Monitor My Watershed data portal. |
samplingFeatureUUID | The sampling feature UUID for the site on the Monitor My Watershed data portal. |
This can be used as an alternative to adding the logger and client in the constructor. This is slightly "safer" because we expect the publishers to be created in the "global scope" and we cannot control the order in which objects in that global scope will be created. That is, we cannot guarantee that the logger will actually be created before the publisher that wants to attach to it unless we wait to attach the publisher until in the setup or loop function of the main program. In reality, it is very unlikely that this is necessary.

int16_t publishData(Client* outClient) override
Utilize an attached modem to open a a TCP connection to the EnviroDIY/ODM2DataSharingPortal and then stream out a post request over that connection.
Parameters | |
---|---|
outClient | An Arduino client instance to use to print data to. Allows the use of any type of client and multiple clients tied to a single TinyGSM modem instance |
Returns | int16_t The http status code of the response. |
This depends on an internet connection already having been made and a client being available.
