 # ICE9 Bluetooth Sniffer
 
-Bluetooth sniffer for Wireshark and HackRF, BladeRF, and USRP that can
-listen to between 4 and 40 channels simultaneously.

-## M1 VkFFT Preview
-
-This is a preview branch that showcases real-time performance sniffing
-all 40 BLE channels on an M1/M2 Mac using a bladeRF. This version only
-runs on macOS, only supports bladeRF, and is fixed to 96 channels
-centered at 2441 MHz. It reliably segfaults on exit, but it should be
-harmless.
+Wireshark-compatible all-channel Bluetooth sniffer for bladeRF, with
