AWESOME...

Ive cracked it. I had to write the 128 bit and 16 bit codes into the
ble_db_discovery_evt_register(&btn_uuid);
I'm so happieee : )

dunno about Windoze, but on Android there's the "snoop" log:

I think I am honing in on my issue.

I am trying to connect a basic MIDI device, and I can see in nrfconnect that it manages to get the service and from that it then manages to get the characteristic.

To try and do the same in pc-ble-driver I manage to connect and then on
ble_db_discovery_evt_register
I try and register out with
btn_uuid.uuid = 0xFFE0;
and I get - BLE_DB_DISC:INFO:Service UUID 0xffe0 Not found

I try
btn_uuid.uuid = 0x180A;
but I dont think I am getting the characteristics that I want for MIDI so when I then try and follow up with a GATTC write BLE_GATT_OP_WRITE_REQ I get nothing.

I feel I am so close, I have the device connecting but I cant get the correct characteristics out.
Is there a way that I can see what nrfConnect BLE is doing to do the same?

I think what you really need to be doing is looking at the pc-ble-driver:

Thank you for the advice,

I took a look at setting up a UART project following this example here:
https://visualgdb.com/tutorials/arm/nrf51/uart/

But I am getting stuck with certain things not matching up on my environment and my inexperience in this area is preventing me from being able to debug it properly and tailor the project to work with the devices I have.

I know I can see the BYTEs I need in nRFConnect on COM 3 so I will see if I can somehow get those out perhaps with com0com so I can use them elsewhere.

One more question, is there a way to get the BYTEs directly out of nRFConnect instead of trying to mirror the serial port with com0com?

Thanks again,

Lindsay.

So you're basically doing the same as in this thread - just on PC host instead of a Linux host.

So the suggestions in my first reply should be applicable...

Note that you can use (something like) com0com to "sniff" a virtual COM port connection ...
