All the addresses are known.

I've solved this problem by using a timer to do the following things sequentially.

Judge if the connection is valid
Removes the contents of the filter
Reset the value of the filter to filter the address
Enable filter
Start scanning

Thank you for your time and reply.

Are all the addresses known before starting connecting to the devices? The scan filters are typically used to connect on a match, not used to prevent reconnection to previously connected devices. If the addresses are not known, I think it may be more efficient to store the addresses in a list and parse the list to check if the device has already been connected before initiating a connection to the device.

Hi,

How should I use this nrf_ble_scan_filter_set() function to filter 500 peripherals' adress.

Best regards.

Hi,

The softdevices only support up to 20 concurrent connections. If you need to connect 500 peripherals, you will have to cycle through all the devices sequentially. You can store the address of the previously connected peripheral if you do not want to reconnect it.

Best regards,
Jørgen
