I have already try to execute the procedure described in the link that you posted, but the smartphone Xperia don't connects at the nordic board.

In this moment, i don't have the smartphone Xperia available, when it's possible i execute the test to search to connects the smartphone with other example application.

that is not how you delete the bonding information. Has the Xperia been connected to that specific nRF earlier when the nRF was running another application that used bonding or pairing? Can you please google how to delete Bluetooth bonding information on the Xperia, and see if there is any bonding information stored? Bonding information is stored in Flash, so turning off the power doesn't erase flash. Just like your pictures are saved between the power cycles on the phone.

Have you done any changes to the cscs example? Can you try another example? E.g. the ble_app_uart example? Just to check if you are able to connect to it with the same phone or not.

"Are you sure that this is not related to bonding being stored on one device but not the other?" Yes, i'm sure because there wasn't others smartphone power on. I have tried to power off and power on the smartphone Xperia, but it didn't connects.

In the nrf52840 board aren't error, why the led 1 on the board pass from advertising (led blink each 500ms about) to connect state ( led1 on steady ). Unfortunately i don't know check what say the log nrf.

While i have try to connect the application with the APP nrfConnect installed in the xperia smartphone and returns this error: Error 34 (0x22): GATT CONN LMP TIMEOUT. From the smartphone xsperia i don't connection not even using the funcionality bluetooh in the 'settings' section.

When i try to connect on the APP nordic remains on the state 'CONNECTING...' and as i have already say in the nordic board the led1 becames on steady. Can you help me ?

Thanks you

Are you sure that this is not related to bonding being stored on one device but not the other?

Try to erase the bonding information on both devices, and see if that helps. Let me know if you are not sure how to do this.

If that doesn't help. What happens when you try to connect with the Xperia? What does the nRF Log say? And what does the Xperia say? Are you able to see the advertisements?

Best regards,
