Flowcode Support Board

External code can be included in Supplementary Code. See: https://www.flowcode.co.uk/wiki/index.p ... ntary_Code

Instead of adding the code directly to Flowcode, add statements into Supplementary Code such as the following to point it at external files:
You can then call any external C functions in your code by adding a C icon to your Flowcode macros.

Created an another component using AI for ESP32 that a single macro call enables direct email dispatch via SMTP (SSL/TLS) for simple notifications like sensor reading or system alerts. Ensure that ESP32 has an active WiFi connection before calling the macro.

Input Parameters
HOST_ADDRESS: SMTP server (e.g., "smtp.gmail.com").
PORT: SSL/TLS port number. (465 for Gmail)
USER_NAME: Full sender email address. (e.g., "yourname@gmail.com")
PASSWORD: 16-character Google App Password (e.g.,"xgdihlrtexusksta") not login password
DESTINATION: Recipient list (e.g., "a@mail.com, b@mail.com")
SUBJECT: The title of the email. (e.g., “Temperature Alert")
MSG_LINE 1 - 4 : Four lines for your data strings (128B per line)

Please note that I have specifically tested this component only on the ESP32 Wroom 32 module with Gmail account

That's very neat, thankyou.

One suggestion - if you have a string as a parameter to a macro - untick the 'make local copy' check box - this saves duplicating the string (which takes time and memory) - and you can then pass strings of any size.

So - you could have string msg_text[10000] as the parameter to the function - and this is just passed as a 32bit pointer (and a length FCsz_MSG_TEXT) - if the 'make local copy' is ticked it will copy the string to a local (10000 byte) buffer - but otherwise doesn't.

Hi

This sounds a very cool component. Thank you for creating and sharing.

I hope to test it for myself soom.

Regards
