3.4 Updating the Bluetooth Low Energy Sniffer Firmware

The Bluetooth LE Air Sniffer USB dongle comes pre-programmed with the sniffer firmware. If the user wants to update the firmware, the user can do so by following the steps given below:
  1. Go to the Microchip Bluetooth Low Energy Sniffer product page.
  2. From the software section, download Microchip_BLE_Sniffer_Package.zip.
  3. Unzip the folder to get the Bluetooth Low Energy Sniffer firmware (.uf2) available in the Microchip_BLE_Sniffer_Package\UF2 folder.
  4. Connect the dongle to the computer, and double press the button. The RGB LED on the dongle turns green.
  5. The dongle appears on the computer as a Mass Storage Device named BLE-DONGLE.
  6. To install the firmware (.uf2) onto the dongle, simply drag and drop the file onto the BLE-DONGLE volume. During the installation of the file, the RGB LED on the dongle rapidly blinks in red and turns OFF upon completion.
  7. After re-plugging, the USB dongle is detected as “USB Serial Device (COMXX)” under Ports in the device manager
Note:
  1. Do not delete any file/folder when the USB dongle is detected as a mass storage device BLE-DONGLE.
  2. If you try to Flash the same firmware version that already exists in the dongle, it will skip the firmware update and restart.
