Here4 doesn't function when used simultaneously with Hereflow

Here GPS
1

Hello,

When I try to use the Here4 and Hereflow simultaneously, they stop functioning. However, they both work fine when used individually.

I have tried connecting them both via a splitter to CAN1, and also tried connecting them separately to CAN1 and CAN2. I also have a Here3+, which works fine when connected via a splitter to CAN1.

I suspect the issue might be due to either a power shortage or communication conflict. Could someone please help me understand the cause of this issue and suggest a solution?

Thank you.

@iPso few things to check:

  • CAN TERMINATION settings on Here4. You may need to turn it on.
  • Power supply, please ensure that you power Cube through a proper power supply, not USB.

Hello @sidbh
After adding a new bypass line from the power source, I was able to use it simultaneously!
Thank you for the advice!

However, the power consumption has increased, and the flight time has decreased by about 40%.

Do you have any good suggestions or improvements for this?
I would appreciate any advice you can offer.

Here is the download link for today’s flight log.

@iPso please share logs either via Google Drive or https://droneshare.cubepilot.com .

It is highly unlikely that GPS modules are going to have such a severe impact on power budget. I would look into current draw by your motors, and see if that has changed between the logs.
