This would trigger an OTA update query to the Bolt Cloud, with the current firmware version of the Bolt WiFi module.
If a new firmware for the device is available on the cloud, the device downloads the firmware, and enters bootloader mode and flashes the new firmware into its memory. This takes about 40 seconds. The device then restarts and connects to the wifi network that it was earlier connected to.

You can find out the current version of you Bolt device by running the following link in a web browser.

The latest firmware version available is 1.0.6 for Bolt hardware version 2.
