Bluetooth Host Controller Interface (HCI) sniffing provides valuable insight for Bluetooth developers. With HCI sniffing you have a transparent view into the commands and events
that are being sent back and forth between the host stack and the controller. The hardwired HCI interface is always "on" and does not need to synchronize with air interfaces.
It gives the developer or tester a better overall view on both air and HCI transports.
For example a device may not transmit an air packet due to an issue between host and host controller.
Looking at the HCI commands and events through Frontline's HCI protocol analyzers will quickly establish where the problem lies. This ability is key to ensuring that a packet being sent from the host stack is received by the controller.
Frontline HCI products and transports:
All of the Frontline HCI sniffers can be used as stand-alone sniffers or as options with FTS4BT and BPA 500 (the only exception is HSU).
Capture and decode HCI
Frontline's HCI protocol analyzer(s) are very portable and require very little set up. They provide detailed information and display all HCI commands and events in one
The HCI sniffer displays and decodes all the protocol layers all the way through the profile. The profile list includes:
