Hi,
I see the Matter CHIP integration uses BLE for commissioning, so to advertise a ble service the documentation advises to use NUS.
What about scanning for ble devices and connecting to them?

Hi,
You can use the CHIP Tool to scan and commission. See Working with the CHIP Tool.

No, I meant I need to scan for ble devices from the nrf5340 and connect to them.
Can I only add BLE advertising alongside a Matter application? I specifically need scanning like bt_le_scan_start
Hi,
Amanda is out of office. So I'm replying instead.
Did you get any errors when calling bt_le_scan_start() ?
Yes, that's the function that I'm trying to use and it's throwing error -5 because of BLE Set Scan Parameters UNKNOWN HCI COMMAND
Here is the matter light_bulb sample with just bt_le_scan_start() inside app_task.cpp and even flashing it on a 5340dk it throws error -5
Hi,
NCS v2.5.0 provides the Matter Bridge feature to scan and connect BLE devices. Here is the Matter bridge application. Hope it could help.

I'm trying the Matter Bridge application and after enabling CONFIG_BRIDGED_DEVICE_BT=y and flashing on my nrf7002-dk but matter_bridge scan is not outputting any device in the console even though I have many 5340s advertising. Do I have to modify the code to be able to scan any ble device?
Hi,
What applications are those devices running?
Please be aware that
To test the Matter bridge application with the Bluetooth LE bridged device, you also need the following:
An additional development kit compatible with one of the following Bluetooth LE samples:
See the Requirements section.
Do you build the sample with the following commands?
west build -b nrf7002dk_nrf5340_cpuapp -- -DCONFIG_BRIDGED_DEVICE_BT=y -DOVERLAY_CONFIG="overlay-bt_max_connections_app.conf" -Dhci_rpmsg_OVERLAY_CONFIG="absoule_path/overlay-bt_max_connections_net.conf"
Replace absolute_path with the absolute path to the Matter bridge application on your local disk.
See Configuring the number of Bluetooth LE bridged devices for the details.
-Amanda H.
So if I want to add support for different peripheral ble devices with other UUIDs I have to add a class and modify some code inside the ble_providers?
You could add into https://github.com/nrfconnect/sdk-nrf/blob/v2.5.0/applications/matter_bridge/src/app_task.cpp#L67-L72
-Amanda H.
The bridge sample uses WIFI for Matter, what about using Thread?
I've been having issues enabling it, as it causes the build to require multiprotocol_rpmsg child image so after adding the multiprotocol's .conf and CmakeLists line from the weather station sample it builds and I start getting the -5 error again. I tried to add CONFIG_BT_CENTRAL=y to the conf of multiprotocol but then it overflows the flash by 23488 bytes.
From what I can see there is no example of CHIP + Thread + BLE scan right?
