Updating the DA2 firmware

Firmware is software that is embedded in the DA2 receiver, and enables the receiver to operate. Occasionally firmware updates may become available for your DA2. Updates may include functionality improvements, security patches, and bug fixes.

Use the Trimble Mobile Manager app to download and send the update to your DA2 using the Bluetooth connection to your Android or iOS device.

Firmware updates for DA2 typically take 5-10 minutes. You cannot use the DA2 during the installation process.

To check for and install firmware updates:

  1. Make sure you have an active internet connection on your Android or iOS device.

  2. Connect the DA2 to your Android or iOS device.

    When the Trimble Mobile Manager software connects to the GNSS receiver, it checks the installed firmware version. If a firmware update is available, a pop-up message appears on-screen, and an update tile appears in the Home screen and the Position Source screen, indicating an update is available for the connected position source.

  3. Tap the Learn more button in the update tile. The Software Update screen appears, showing information about the update.

    If you decide you don't want to update the receiver right now, tap Remind me later to defer the update.

  4. To download and install the update immediately, tap Download and install now.

    While the receiver is updating, the LED on the receiver flashes yellow. The Software Update screen shows the progress of the download and installation.

  5. When the update is complete, tap Done.

  6. The receiver automatically restarts. During restart, the LED on the receiver turns off and then turns on flashing blue, before changing to solid blue, indicating the Trimble Mobile Manager software has reconnected to the receiver.
