This article details how to update the Bluetooth module firmware on your Hawk Bluetooth Card.
Please note, that this is highly recommended for Bluetooth cards made before July 2024 (SNs less than 1059089) or if you are using the Barra Radar with the Hawk.
Updating this firmware will reduce the device's sleep current when using the Hawk Lite.
It is also required for much of the functionality introduced in Bluetooth Card FW v1.6 and later, including Generic Analog mapping and compatibility with the Barra Radar.
Update Bluetooth Card Firmware
To update your card firmware (not the Bluetooth module on the card), please follow the below article. Please note that the Hawk Bluetooth card and the Hawk Bluetooth module have different firmware. The Bluetooth module firmware cannot be updated OTA. You must use the DM link provisioning tool.
