No Bluetooth connection on nRF52833

Hello,

The sample found in NCS\nrf\samples\bluetooth\peripheral_cgms is a sample that will request a 6-digit pin when you try to enable indications on the measurement characteristic.

Different phones may act differently. Some will try to pair if it sees that a characteristic is "protected", while others will try to do it only when that characteristic is being used. It is however possible to make the application running on the nRF request the pairing/bonding process as well. To do this, you can use bt_conn_set_security(). (you can see how it is done in the connected event callback in the central_uart sample)

Best regards,

Edvin

Thanks for your help MJJ, it works.

Is there any sample to program nRF52833, that require user to enter password to connect to phone's Bluetooth?

The nRF52833 DK does not come pre programmed with an application.

You could use Quick Start applet from nRF-Connect-for-Desktop to program a sample that will allow you to connect to a mobile device.

Or you can compile and program a sample using nRF-Connect SDK - Installing the nRF Connect SDK.
