EzData is an IoT cloud data storage service provided by M5Stack, allowing different devices to insert or retrieve data into a storage queue through a unique token
, achieving data sharing among devices.
Important Notes:
1. All the following operations depend on the unique token
, which is fixed in the same browser environment. Please copy the token before use.
2. If there is no data operation within half a year, the data queue corresponding to that token will be cleared.
3. Data will be sorted in descending order of insertion time (the last inserted data will be at the top of the list), and data will be cumulatively saved.
get value from topic " " with token " "
save value " " to topic " " with token " "
get value from list " " offset " " count " " with token " "
save value " " to list " " with token " "
remove topic " " with token " "
This program saves data to a specified topic and data list.
This program retrieves data from a specified topic and multiple data from a data list in one go, and clears the queue.
Run the above programs on two different M5 devices, triggering data saving and retrieval via button presses.
