How to update u-blox on here 3 GPS?

dlech · April 29, 2021, 10:09pm

I’m trying to follow https://docs.cubepilot.org/user-guides/here-3/here-3-manual#2-here3-u-blox-chip-firmware-update

This step.

However, I don’t have the Menu button. Instead, it looks like this:

Where do I set up the CAN pass through?

Thanks. Are the docs on GitHub? I would like to make a PR to say that in the docs. It gives a version number, but it isn’t clear that it means the beta version.

## Here3 GPS Manual

### Overview

The Here3 GPS is a high precision GNSS system that supports RTK mode, built with CAN protocol. It is also designed to be dust-proof and splash-proof up to a certain limit. Equipped with STM32F302 processor, the Here3 provides faster processing speed and better reliability.

The Here3 has built-in sensors including compass, gyroscope, accelerometer, and status LED. It runs on Chibios real-time operation system. Its open-source structure is ideally suited to developers who need specialized requirements on their navigation system.

### **Feature**

1. Cost-efficient high precision and RTK supported GNSS chip \(base station needed for RTK\). Positioning accuracy down to centimetre-level in an ideal environment.
2. Brand new design with improved visibility on signal LEDs. Better dust and water resistance \(Not guaranteed to be water-proof under any situation due to the complexity of the operating environment\).
3. The high data rate, upgradeability, noise immunity, and real-time features benefited from CAN protocol
4. Equipped with STM32F302 high-performance processor in a real-time operating system. The framework developed by Hex provides additional stabilities. Supports future firmware updates.
5. Support from ground control software. Future updates will be available from Mission Planner.
6. Built-in a complete set of Inertial Measurement Unit \(compass, gyroscope, and accelerometer\), which satisfy advanced navigation needs.

@dlech I had this same issue, so thanks for posting. What firmware are you using on the AP? We might want to add this to the PR docs.

Sir I am too using here3 gps but it doesnt show in the UAVCAN for Here 3 update although p1 and p2 driver and d1 and d2 driver and gps type selected as UAVCAN

try connecting with the cable and not by the telemetry module.

I found out recently that if you are using Cube Orange, that you cannot follow the instructions exactly. Do not connect with MAVLINK first. Also, restart Mission Planner to make sure it is not in a bad state. Connect the Cube Orange with the USB cable. Then go to the Windows Device Manager and look for the COM port on the Cube Orange that is for SLCan. Select this COM port in Mission Planner, but do not connect. Go to the UAVCAN page in Mission Planner. Click the SLCan Mode CAN1 button. A dialog box will open up - it says you might be doing things wrong, but it is fine - click OK. Then you should be connected to the GPS.
