Function documentation

UbidotsPublisher(Logger& baseLogger, uint8_t sendEveryX = 1, uint8_t sendOffset = 0) explicit

Construct a new Ubidots Publisher object.

Parameters
baseLogger The logger supplying the data to be published
sendEveryX Currently unimplemented, intended for future use to enable caching and bulk publishing
sendOffset Currently unimplemented, intended for future use to enable publishing data at a time slightly delayed from when it is collected

UbidotsPublisher(Logger& baseLogger, Client* inClient, uint8_t sendEveryX = 1, uint8_t sendOffset = 0)

Construct a new Ubidots Publisher object.

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
sendEveryX Currently unimplemented, intended for future use to enable caching and bulk publishing
sendOffset Currently unimplemented, intended for future use to enable publishing data at a time slightly delayed from when it is collected

UbidotsPublisher(Logger& baseLogger, const char* authentificationToken, const char* deviceID, uint8_t sendEveryX = 1, uint8_t sendOffset = 0)

Construct a new Ubidots Publisher object.

Parameters
baseLogger The logger supplying the data to be published
authentificationToken The authentication token from Ubdots, either the Organization's Integration Token (under Users > Organization menu, visible by Admin only) OR the STEM User's Device Token (under the specific device's setup panel).
deviceID The device API Label from Ubidots, derived from the user-specified device name.
sendEveryX Currently unimplemented, intended for future use to enable caching and bulk publishing
sendOffset Currently unimplemented, intended for future use to enable publishing data at a time slightly delayed from when it is collected

UbidotsPublisher(Logger& baseLogger, Client* inClient, const char* authentificationToken, const char* deviceID, uint8_t sendEveryX = 1, uint8_t sendOffset = 0)

Construct a new Ubidots Publisher object.

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
authentificationToken The authentication token from Ubdots, either the Organization's Integration Token (under Users > Organization menu, visible by Admin only) OR the STEM User's Device Token (under the specific device's setup panel).
deviceID The device API Label from Ubidots, derived from the user-specified device name.
sendEveryX Currently unimplemented, intended for future use to enable caching and bulk publishing
sendOffset Currently unimplemented, intended for future use to enable publishing data at a time slightly delayed from when it is collected

StringgetEndpoint(void ) override

Get the destination for published data - generally the host name of the data receiver.

Returns String The URL or HOST to receive published data

voidsetToken(const char* authentificationToken)

Set the device authentication token.

Parameters
authentificationToken The authentication token from Ubdots, either the Organization's Integration Token (under Users > Organization menu, visible by Admin only) OR the STEM User's Device Token (under the specific device's setup panel).

uint16_tcalculateJsonSize()

Calculates how long the outgoing JSON will be.

Returns uint16_t The number of characters in the JSON object.

voidprintSensorDataJSON(Stream* stream)

This generates a properly formatted JSON for Ubidots and prints it to the input Arduino stream object.

Parameters
stream The Arduino stream to write out the JSON to.

voidprintUbidotsRequest(Stream* stream)

This prints a fully structured post request for the Ubidots API to the specified stream.

Parameters
stream The Arduino stream to write out the request to.

voidbegin(Logger& baseLogger, Client* inClient, const char* authentificationToken, const char* deviceID)

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
authentificationToken The authentication token from Ubdots, either the Organization's Integration Token (under Users > Organization menu, visible by Admin only) OR the STEM User's Device Token (under the specific device's setup panel).
deviceID The device API Label from Ubidots, derived from the user-specified device name.

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.


voidbegin(Logger& baseLogger, const char* authentificationToken, const char* deviceID)

Begin the publisher - linking it to the logger but not attaching a client.

Parameters
baseLogger The logger supplying the data to be published
authentificationToken The authentication token from Ubdots, either the Organization's Integration Token (under Users > Organization menu, visible by Admin only) OR the STEM User's Device Token (under the specific device's setup panel).
deviceID The device API Label from Ubidots, derived from the user-specified device name.

int16_tpublishData(Client* outClient) override

Utilize an attached modem to open a a TCP connection to the Ubidots API 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.
