Host Controller Interface (HCI) Access for RN42

Is there a firmware update in order to have the chip configured in Host Controller Interface (HCI) over USB mode?

HCI mode is only available by ordering part RN42HCI and RN42HCI for UART interface, or RN42U and RN42U for USB interface. For more details on how to use these, see the "Class 2 Bluetooth® Module with EDR Support" datasheet in the "Documents" section of the RN42 product page.

Microchip offers HCI mode in two hardware interfaces:

  • HCI over UART (RN42HCI-I/RM)
  • HCI over USB (RN42U-I/RM)
