Hi All, i'm somewhat confused with these two terms. I have a device which is essentially a BLE badge reader, according to the spec-sheet I need to implement a GATT server with own GATT service...

I am reading descriptors using the code from: https://www.b4x.com/android/forum/threads/ble2-how-to-read-a-bluetooth-characteristic-descriptor.102483/#post-643594 but waiting for the response from the BLE device using polling: https://www.b4x.com/android/forum/threads/ble2-how-to-read..., that will wait for a callback from the gatt.RunMethod("readDescriptor" request?...

This library replaces the previous BLE library. It is simpler to use and it is more powerful. Its API is based on B4i iBLE library which makes it easy to reuse B4i code.

See the attached example. Note that the important code in in the Starter service module. Edit: A new version of BLE_Example was uploaded...

but I didn't generate new UUIDs for the characteristics. What was wrong with the previous characteristic ids? Did they need to change? Did they change? As long as both sides of the BLE GATT connection agree on the ids, whatever they are, should all work fine. If not, then... nRF Connect app to the rescue! (as in: it can confirm that at least one side of the connection is working)....

is there any code in B4A platform to deal with it ? If you mean: for that particular Bluetooth sensor model, then: probably not. I would expect that the live temperature reading would just be a standard read of a standard BLE GATT characteristic, which can be tested (no programming required) using nRF Connect app BLE utility program and then, presuming that it works there, coded up using the B4A "internal" BLE2 library....

Well it will do for normal ESP development. But when you have a product, that is locked within an enclosure in a DIN Rail its kind of hard for the user. And the user is not an IT guy. I as thinking of BLE GATTs, I know I did something like than long time ago, based on ESP32, but it was with MongooseOS interpreter on the ESP...

Using BluetoothGatt, the way to set the Phy is via setPrefferedPhy and to read the Phy is to use readPhy. Both methods communicate their results using callbacks via the BluetoothGattCallback. This wish is to expose the callbacks onPhyRead and onPhyUpdate. This would round out (actually implement every callback in BluetoothGattCallback) the already excellent updated BLE2 library....
