Bobber OTAs will automatically update your firmware, but you can always use the Bobber Diagnoser to confirm your hotspot is operating with the latest firmware version.
Once you access your Diagnoser, you will be able to locate your Bobber OTA version displayed at the bottom of the Diagnoser menu. Your Helium firmware version can be located by selecting Miner Information.
You can view the latest OTA by going to this page.
