Sniffer on OSX - revisited

[David Elvig]

It looks like the last discussion of Sniffer on Devzone was 2-3 yrs ago.

I’ve ordered the nRF Dongle and will download the Windows-based nRF Sniffer app.

i can run this with WireShark on a Windows VM on my Mac, though I would like a Mac OSX option.

- Any news on that front?

- Any way the Bluetooth hardware built into the MacBook could serve a Mac Sniffer app?

thanks!

did you actually give the right path to the UART, it is usually in /dev .

Verify that by using the "screen <port> 460800", you should see some characters on the screen.

[David Elvig]

I've done the following:
- Identified the serial port with this partial ls from \dev: 

cu.Bluetooth-Incoming-Port	ttyv0
cu.LGHBS760-CSRGAIA		ttyv1
cu.MALS				ttyv2
cu.SOC				ttyv3
cu.usbmodem1451061		ttyv4
cu.usbmodem1461			ttyv5
disk0				ttyv6
disk0s1				ttyv7

    It is the "cu.usbmodem1461" entry that appear/disappears with plugging/unplugging the dongle

I typed the following into Terminal:      
        screen cu.usbmodem1461 46800

...resulting in:

No typed keystrokes show, and it responds only to the Ctrl-a-Ctrl-k command to quit.

[David Edwin]

The baud rate I suggested was 460800 (not 46800 as I see in your screen shot). 
Please connect to the port at 460800 and see if you are getting characters on the "screen".

Thanks

[David Elvig]

Thanks for your patience.

I get the same result as above with

"screen cu.usbmodem1461 460800"
