See this guide for migrating. ZIP Library See this for all functions details. See Other authentication examples for more authentication methods. Some authentication methods need the token generaion and exchanging process which take more time than using the legacy token. The authentication with custom and OAuth2. While using Email and password sign-in which use in wildgame innovations xb380 crossbow id token generation process takes minimum time.

The time used in data transmission also depend on the size of token string which is the part of request header. The legacy token size is smallest, approx 40 bytes, the lowest data trasmission time averaged - ms for 1 byte of payload. The id token using sign-in Email and password has approx bytes in its size, the maximum data trasmission time averaged - ms for 1 byte of payload.

The http session will be reused when you dont share a Firebase Data object usage among with the normal Firebase calls i. The system time setting is required when you use the custom and OAuth2. See RTDB examples for complete usages. These functions return boolean value indicates the success of the operation which will be true if all of the following conditions were met.

The database data's payload response can be read or access through the following Firebase Data object's functions. Read the data which its type does not match the data type in the database from above functions will return empty string, object or array. BLOB and file stream data are store as special base64 encoded string which only supported and implemented by this library. The encoded base64 string will be prefixed with some header string "file,base64," and "blob,base64," for data type manipulation.

The above functions return boolean value indicates the success of the operation which will be true if all of the following conditions matched. Only setBlob and setFile functions that make a silent request to Firebase server, thus no payload response returned. The priorityvirtual node ". ETag unique identifier value assigned to Firebase's set functions is used as conditional checking. If defined Etag is not matched the defined path's ETag, the set operation will fail with result Precondition Failed.

ETag at any node can be read through Firebase. ETag value changed upon the data was set or delete. The server's Timestamp can be stored in the database through Firebase. The unique key of a new appended node can be determined from fbdo. ETag was not available after push unless read the ETag at that new appended unique key later with Firebase. The server's Timestamp can be appended in the database through Firebase.

Return of large JSON payload will cost the network data, alternative function updateNodeSilent should be used to save the network data. To filter or query the data, the following query parameters are available through the QueryFilter class.

Use key or full path of child nodes as the orderBy parameter if all values of the specific key were used for the query. The above orderBy parameter can be combined with the following parameters for limited and ranged the queries.

Function beginMultiPathStream is to subscribe to the stream changes at a defined parent node path with multiple child nodes value parsing and works with setMultiPathStreamCallback. Function setStreamCallback is to assign the callback function that accept the FirebaseStream class as parameter. The FirebaseStream contains stream event and data and haas st25y function calls are similar to Firebase Data object.This Arduino programming tutorial has three simple steps: Authorize our device using OAuth 2 and get the token to exchange data with Google.
