NRF52 PDK on Linux with bluez tools

[Zero.cool]

Hi ,

I am working on customize tools utilizing the nrf python codes.

In linux I came to know about BLE libraries bluez and also about hcitools.

I have setup for linux 64bit ubuntu 14.04 which have all codecs which I found over net required for BLE, installed.

There are nrf apps also downloaded.

So the problem/query is I am able to detect and utilize my nrf52pdk using nrf connect app in linux.

however If I use hcitools I am not able to see any device connected.

Also in bluetoothctl I don't get any device detected.

The firmware on the nrf is already flashed via nrf connect app and working So I believe the firmware on PDK is correct.

I also went through the forum and previous questions here but not able to find answer (as they are for older version)

I will be thankful for any pointer for this.

Thanks,

Hi,

nRFconnect  uses serialized softdevice APIs to control the connectivity chip similar to the setup shown here (PC == application processor): http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.2.0/nrf51_setups_serialization.html?cp=4_0_0_1_4., while the bluez host in Ubuntu will only work with connectivity HW that supports the HCI interface. Our bluetooth stack (softdevice - host + controller) does not expose this interface to the application.

Here are some options

1. Use the pc-ble-driver with Nordic HW to create your custom tool. Python and Javascript wrappers are available. 

2. Create a HCI compatible controller with Nordic HW and Zephyr (whitepaper)

3. Get a standard BT HCI USB dongle
