Hi, I send to service 65333333-a115-11e2-9e9a-0800200ca100 and characteristics:
65333333-a115-11e2-9e9a-0800200ca101
65333333-a115-11e2-9e9a-0800200ca102

You write to both of them? Do they do different things? Or do the same thing?

What do they do, as in: how do you know the string has been received by the BLE device? Does it, say, turn a LED on?

If we had to choose which one to get working first, *101 or *102, which one would we do?

For me they do same things.
*101 = Writable, indicate
*102 = Writable without response, Notify
*103 = Indicate

I can see a rx buffer of device and when I send data with LightBlue, I see in buffer same data transmitted.

At the moment, *101 or *102 is indifferent.

In LightBlue, I can send data only if I tap to "Subscribe" button, otherwise it tell me "Data sent" but I don't receive any.
For me, this should not crashes the b4a program.
In doubt I ask you if is there perhaps a subscription function?

Thanks.

I probably took a small step forward.
Now when I send data the app don't crash, but I can't receive data.
Through "BLE Scanner" app, I've seen that I can receive data only if I enable flag "Indicate".
Can you tell me if exist a funcion to call to enable it?
Thaks.

It works
SetIndication must be set before dataWrite.
Thanks at all for help
