Hi,
I have followed this threads, and it does't work.
I have tried the Test Too12 with three versions(12.2.1, 12.7.1, 12.8.1).
If I use KW01Z128_Sniffer.srec to reflash the dongle, all of these tools cannot detect the dongle.
So, I use the method in the link as below.
Packet Sniffer/USB Dongle for Kinetis KW0x|NXP (2.3 Download the sniffer application)
After that, the dongle can be detected in the tool with version 12.7.1 and version 12.8.1.
Although the dongle can be detected, I still cannot capture any sniffer through it.
