BluetoothLE extension 20200828 released

Hello,

Could you, please, tell me how can I send and receive int32 data over BLE using this extension?
In fact, I want to sent the following sentence: 0FFFFFFF to one board with BLE; this question is related with this post: Sent data to Thunder Sense over BLE
Moreover, when I use "Register for Integers", then the application stop to display new arrived data over BLE.

Thank you,

Mihai
