What will the BLE beacons show up as in Wireshark when programmed with peripheral example code

[priya]

log.txtI have programmed my nRF smart beacon with example peripheral code with DK52. My beacon now flashes red. I am using the nordic sniffer to sniff ble packets in wireshark. My executable crashes after 5 seconds since there is lot of BLE traffic. How can I identify my beacon device in wireshark and filter it.

Which version of the JLink OB firmware is on your nRF51 Dongle? You should use v5.10n, which can be downloaded here. You also need to use Wireshark v1.10.x, here is the link to the newest compatible version, i.e. v1.10.14.

In order to downgrade the JLink OB FW on your nRF51 dongle you'll need to follow the steps below:

1. Start JLink.exe with the nRF51 DK/Dongle connected to your computer
2. Enter the following command, exec invalidatefw , to invalidate the J-Link Firmware. This will promt you to upgrade the firmware, press “Yes”
3. Navigate to C:\Program Files (x86)\SEGGER\JLink_V510n, open the commandline in this folder and enter the following nrfjprog command nrfjprog --jdll JLinkARM.dll --readcode delete_me.hex
4. You are then promted to update the firmware again, press “Yes”.
5. The nRF51 DK/Dongle is now using the Segger J-Link v5.10n firmware. If you use nrfjprog afterwards you must not upgrade the J-Link OB firmware if you are promted, i.e. press “No”. Otherwise you have to repeat the steps above.

I was unable to find the command line . There is one executable that ends in CL and crashes as long as I open it. I uninstalled all the versions of Jlink I had. My sniffer still crashes after 3 secs. Please help!!
