Bobcat Miner OTA Update - 11/04/2021 + New Diagnoser Features

Nov 4, 2021 - Bobcat pushed the latest OTA update at 02:00 PDT today.

The following updates occurred in this OTA:

Bobcat Miner Firmware updated to

Several Optimizations for the Diagnoser

1. The Bobcat OTA version is now displayed at the bottom of the Diagnoser menu

2. We’ve added a light bulb icon that reflects your hotspot’s actual LED light status.


When you perform a resync, reset or fast sync, the light bulb color will turn white to indicate progress has started. You will need to refresh the menu in order for the status change to display.

During this time, your hotspot's LED will first turn yellow, before finally turning green - make sure the hotspot does not lose power or internet connectivity.


3. Remove relay status

The diagnoser will now port forward 44158 if your router's UPnP is enabled and 44158 isn't opened yet. This automatically removes the relay status for you. Please disable UPnP if you don't want to automatically forward port 44158. You can still open the port manually.


4. Ports

On the /miner.json page, you will see the open/close status of these ports.

Port 44158 - If the status is open, it means this port can be accessed from the internet. Your hotspot can still show relayed however, if the Nat_Type is not "none".

Port 22 - This port should be closed. Only open port 22 if Bobcat technical support has requested that you open it.

Port 80 - This port should be closed, although it will be alright if the status is open, because the diagnoser has disabled external IPs from visiting so it’s not possible for others to attempt to manipulate your hotspot by taking hold of the diagnoser.

5. Display of your public IP in the /miner.json page

Your public IP will be shown inside the miner (5s) page


Other updates included in this OTA

Adjusted network settings to resolve an issue with a small number of hotspots that were unable to connect to Helium seed nodes.


Important Reminders

  1. If your firewall settings have all of China blocked via restriction in both incoming and outgoing directions, your hotspot will not be able to connect to our device management platform and will not be able to receive the OTA updates.

  2. If your hotspot OTA version is older than, please fill out the form here. The team will check this routinely and update any hotspots that are left behind on a daily basis.
