Cannot create long string like base64 on Firestore

[mrschwartx]

When I use this library, I can not create document on Firestore with base64 string.

Base64 is just a string.

Please explain more in detail.

Ok. if I use the old library before async, I create document with base64/long string as values of field that is work. But when I use asnyc that need more time to write and almost failed to create document. Can you suggest me some best example for this case.

You have to understand the basic of the async concept in this library.

It is different from the traditional async library which runs on the other tasks that handled by the FreeRTOS or timer or scheduler.

The time sharing between user code and library code was managed and controlled by user.

It is upon how the async task handler was executed in the main loop function.

If your code is blocking, the async operation will be delayed and when it takes time longer than time out limit, the operation will be stopped and cancelled.

There are some prohibit things that you also needed to know.
 
Please read the library documentation thoroughly for how to use library correctly.
