X-NUCLEO-BNRG2A1 + STM32F411RE

[Pgonz.1]

I'm using the module X-NUCLEO-BNRG2A1 and I uploaded some code to give the BLE module an address, services and characteristics.

Now, when I disconnect the module from my NUCLEO-F411RE and connect it to Arduino or I simply power it up, I can't find the BLE device in any app.
