Bluetooth connection is not working well when connecting to a different phone than the one I previously connected.

Hello

I use nrf52832 and SDK v17.
I am programming BLE using UART service.  So far, there has been no problem with testing with one phone, but if I disconnect the Bluetooth connection and try to connect to another phone, it doesn't connect and also stops the board.

Resetting the board and running it again will connect well with the phone that had problems. But as before, Bluetooth connection is not good with other phones.

Probably, only the first registered one are connected after the board is run, and the others are not connected. I added the peer manager code of HRS example, should I correct this code?

The phones I am testing are Android and IOS.

Thank you.

(I have an additional question.  How do I view more debug outputs? I added DEBUG to the preprocessor, is there another way?)

Hello,

You need to read the example manual in the infocenter.

When you are using the Peer manager, it will store the bonding information in flash.

Unless removing the stored information, it may not allow connecting to other devices.

If you are using nRF5 DK then, you can easy to erase the bonding information by powering on while pressing button 2.

Please refer to the below parts.

Hello, Eugene.

Thank you for helping me.
I used the method of removing the whitelist when the Bluetooth connection was lost.
And it seems to be a success.

Thank you!
