Base64 encoder

[yb0kli]

I found that Annex32 now supports base64 decoder. But there is no base64 encoder. Will it be a base64 encoder function built into Annex?

Use case: I am struggling to send binary data, and currently encode to HEX string that cause the data transmission size doubled. Workable but not efficient.

Thank you.

Yes I'll add the base64 encoder to the list

Thank you very much for your great efforts

Implemented in the version 1.50.8

Yeay! I see this on the newest help file.

FILE.TOBASE64 source$, dest$
Convert the file defined ‘source$’ into the file defined in ‘dest$’. The source file can be in any format and will be encoded in base64 format.

Thank you for your great effort

I was trying simple code with ESP32CAM:

Code: [Local Link Removed for Guests]

wlog camera.picture("/picture.jpg")
file.tobase64 "/picture.jpg", "/picture.txt"
wlog "converted to base64"

The module keeps restarted everytime it runs.

However, if the source file was text, it converted just fine. Does the file.tobase64 has limitation only to text file and cannot work with binary file?

Thank you.

It should work with all the kind of files.
You are right, it do not work properly.
Ill fix it.

Awaiting AnnexCam new release with fixed binary base64 encoding. Thank you...

It has been fixed on the esp32 and esp32-s3.
I'll release the version for the CAM very soon
