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.
I also tried to integrate this sample but I'm still getting error -5 from bt_le_scan_start. I'm omitting bt_enable though because CHIP seems to be already calling it

What sample are you using?

In the Matter: Door lock sample which can advertise with NUS. See Matter Bluetooth LE with Nordic UART Service. You also can connect and test with nRF Toolbox on your Android (Android 11 or newer) or iOS smartphone (iOS 16.1 or newer). See Testing door lock using Bluetooth LE with Nordic UART Service

I am trying to integrate central_uart with my Matter application as you suggested but I'm getting uart_init failed (err -88).
It's failing here:
const struct uart_driver_api *api =
(const struct uart_driver_api *)dev->api;
if (api->callback_set == NULL) {
return -ENOSYS;
}
I've seen from another ticket that it could be the uart_cb callback passed to the init function but mine is exactly the same as the central_uart sample. My uart device is declared in the overlay like this (and it's not disabled):
/ {
chosen {
nordic,nus-uart = &uart0;
};
};
so I'm not sure what could be causing this. I've also tried changing uart mode to async, interrupt driven and other params but with no luck, and meanwhile the scan is always returning error -5.
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.
-Amanda H.
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.
