Hi Ben
Perfect!
SendArray is working for this 3 commands
to send: as buffer as "on" or as string

That means it already works very well.
I have observed that it is already perfectly implemented in ESP32 BLE_GATT.
these practical send/receive IntArray
but one little thing remains in the App BLE_GATT_SPP:

something very small:
If I send, the TX LED is flashing
but if I receive a byte, the RXLED is not flashing(it's not a problem)

Aha sorry I didn't make the new macros public! RX LED should flash now too.
Should be there for you now

Hi Ben
Yes RX Led is perfect!
Also the send/receive IntArray is there.
but one little thing ....
NumValues are usually int or uint
A byte has crept into these three macros.
But it's not really a problem.

Hi Stefan,
The byte is there on purpose as I have to define a byte byffer to use as a go between to convert from bytes to ints and that is fixed at 512 bytes and so more then 256 values in the array would require a bigger buffer of unknown size. It's a compromise but seems to be what I have put in place in the other components that work with arrays of ints.

Hi Ben
I cannot locate the comonents in the web developer.
I'm on it, I think we have already released the web developer version of a component

Ok it looks like it might not be released yet.
I'll talk it through with Steve when he's back and see if we're happy with it. Currently it only deals with Strings so probably needs more effort puttin in to match up with the other components.

Hi Ben
My test with the web app on PC (Windows), iPhone (iOS), and tablet (Android) worked well.
I'm ready to test BLE with a string until Steve gets back
I can only post the HTML file in a ZIP file.

Hi Stefan,
The component as it is atm is here, just copy it into your "C:\ProgramData\MatrixTSL\FlowcodeV11\Components" folder and it should appear in WebDeveloper under Helper.
Here's a quick demo project from Steve.
