BLE CLI NUS COM Port

EGawtry

I am trying to use the RF5 BLE CLI (Nordic NUS driver). 

I need a plug and play COM port for Windows, iOS, and OS/X.  This has to work for a customer.

It pairs easily, but then what?  nRF5 Connect doesn't work (it just gives me a blank screen on connect), and it is pretty useless anyway since it reprograms everything.  The Python script doesn't do anything, and that is also useless for end customer use.  If there was an API or document that explained how to interface an app, that would work as well as a COM port.

    Hello Hung Bui,

    The nRF5_SDK_15.2.0;  Console over Bluetooth Application (internally known as the BLE CLI).   (Harware: Laird BL652: S132 on PCA10040)

    What I need is a real-time BLE monitoring of a Accelerometer and being able to read a history via BLE.  Using XML over the BLE CLI seems to be the only solution I can find after spending a week digging through the Nordic, Laird, and Bluetooth websites.

    I am asking for a way to generate a serial port for the BLE pairing, or some Win32 or Linux sample code to connect to the pairing.

    Thanks,

    -Erik

    Hi Erik, 

    Thanks for the explanation. Please correct me if I'm wrong, you want to use a PC, with a dongle/nRF52 board plugged in, to connect via BLE to another nRF52 board which has an accelerometer ? 

    Since you are using Laird product you may want to contact them to ask about their BLE CLI application. Note that we have no control over Laird's software, nor familiar with any of their implementation. 

    For your application I would sugggest to use our pc-ble-driver we provided here. In the example we use the connectivity(serialization) firmware for the nRF52 instead of CLI. Please have a look here.

    The nRFConnect app is running on top of pc-ble-driver.

    The BLE CLI app is from Nordic, it is part of the nRF5 SDK.  And I am connecting via the Bluetooth built into my PC.

    Thanks for the link.  I will explore the pc-ble-driver.  Maybe that should be part of the SDK?

    Oh, my mistake. We usually refer it as ble_app_cli example.  

    If you want to connect using the native Bluetooth on PC you may want to look for documentation and example from Microsoft. We actually don't have any example that use PC native bluetooth.

    Okay, I wrote an app to talk to the device from Windows, but it won't send any data from BLE to the PC.  I can send from the PC to BLE without a problem.  The notify is never being called.  I have tried with several developers BLE apps to test it and it doesn't seem to be in my app.  Any ideas?  Do I need to send something to tell BLE to turn on the Notify?  I noticed that the BLE_GATT_HVX_NOTIFICATION is being checked for in the initial connect.  Is there some sort of documentation on all this?

    Thanks,

    -Erik
