Android Question BLE2 -- is there an actual tutorial?

[App Dude]

Hi Erel,

I'm struggling to figure out BLE2... I've managed to get data from Android to my device (RN4871-based), but when I send data back I see that DataAvailable is called, but I don't know how to figure out the characteristic and value that was sent to the Android device. The example that's being pushed on every discussion does not clearly tell me the process and what the methods/values for "Characteristic." are. Is there a real tutorial for this that explains the process and how to use the BLE2 library? Yes, I'm licensed. PS, I'm still very new to B4A and Basic.

Thanks.

Hi Erel,

Please don't do it. This is a community forum.

The example shows you how to read the services and characteristics: https://www.b4x.com/android/forum/threads/ble-2-bluetooth-low-energy.59937/
There is also a link to iBLE tutorial which behaves the same as the Android version.

I inherited a project from someone else and that uses Manager_DataAvailable. I'm unclear what exactly that does and how it differs from DataAvailable (as in that example).
This page does not mention it.
Can anyone explain what the differences are?

Start with the BLE example. Once you understand how it works move to your project.

Sure. But can you tell me what Manager_DataAvailable does (as compared to DataAvailable) in the meanwhile?

 

[Erel]

There is no such thing. There is a DataAvailable event. If you initialized the BleManager2 with the event name parameter set to Manager then this will be the sub that handles the event.
