Bobcat Miner OTA Update - 11/16/2021

Nov 16, 2021 - Bobcat pushed the latest OTA update at 20:00 PDT.

The following updates occurred in this OTA:

Bobcat Miner Firmware updated to

This is a Bobcat Miner Firmware update only to optimize the Diagnoser.


1. Blockchain Height display errors corrected

Due to changes to Helium API settings, users had been unable to retrieve the correct blockchain_height, which was incorrectly shown as 0. The updated diagnoser has resolved this issue.

However, if the API is down, you will still see similar displays, such as this:


"status": "Height API Error",

"gap": "-",

"miner_height": "1099848",

"blockchain_height": "0",

"epoch": "28754"


You do not need to intervene in this case.

2. Dig information display errors corrected

A small number of hotspots were unable to retrieve information in dig.json, but this is no longer an issue with the updated Diagnoser.

3. Peerbook

Peerbook information will now display inside the miner.json page

4. IPs and Ports

The miner.json page now displays a user’s public and private IP addresses, as well as port open/close information. Port 22 on your private IP is open by default. Port 22 on your public IP should be closed by default.

5. Add more error types

A few more error types have been added. The miner.json page will address errors with more descriptions to help narrow down issues and facilitate troubleshooting.


This update does not change the Helium miner. PoC events and mining activities will not resume to normal until the block production returns to normal. “Hotspots may continue to be offline after block production resumes and we will need to cut an emergency release for Hotspot firmware after a snapshot has been agreed upon by the Consensus Group”, follow the Helium server’s announcement channels to learn when that happens.

Until the Helium miner update is released and pushed with the next Bobcat OTA update, you might be seeing these in the Diagnoser:

"miner_height": "command",

"epoch": "Error:",


You do not need to intervene. Wait for the next OTA to automatically fix these issues.

11/17 UPDATE

A separate Bobcat OTA update was pushed at 00:45 PST on 11/17/2021. This was a Helium miner update only, updating the miner version to 2021.11.16.3_GA and bumping the Bobcat firmware version to

If your hotspot is stuck on red or yellow: Enter the diagnoser and perform a reset. It will help your hotspot's helium miner to restart and syncing from the latest snapshot. You do not need to perform a fast sync after reset. Most of the times, even if your hotspot is stuck on red, you can still enter the diagnoser. If not, do a power cycle and try again. We will release an OTA today also to help these hotspots to start syncing and catch back up with the blockchain.
