{% hint style="info" %}
Ensure the firmware file is hosted using HTTP. The GPS tracker cannot download firmware files from HTTPS URLs.

Important: Devices running older firmware must first be updated to R01A12V09, which is the required bridge firmware, before applying the latest version. This is the URL for FW: R01A12V09 <http://static-cdn.racemap.com/trackers/firmwares/gl320m/R01A12V09/GL320M_B7K1_R01A12V09.enc>

{% tab title="GL310M" %}
hosted FW: R01A11V05&#x20;

```
AT+GTUPD=gl310m,0,3,10,0,,,http://static-cdn.racemap.com/trackers/firmwares/gl310m/latest.enc,,0,,,0001$

{% endtab %}

{% tab title="GL300M" %}
hosted FW: R20A14V02&#x20;

* Updating the firmware does not reset the previous configuration.&#x20;
* Updating the firmware can be done while charging devices.&#x20;
* If the battery level is too low the device aborts the update process.
* You might send the custom command `AT+GTUPD` multiple times as devices might fail to complete downloading the firmware.&#x20;
* Devices automatically reboot after installing the new firmware, which you observe by flashing LEDs. GL320M and GL310M flash with blue LED, GL300M does not noticeably flash with blue LED.
* Devices remain turned on and will try to reconnect with the tracker management.&#x20;
* The firmware version in the tracker management is automatically updated. Verify the tracker info.
