Here4 not visible anymore

Hello,

I’ve an issue, shortly before the safety release bulletin I got my here 4 stuck, I cannot see it anymore on mission planner. The white led are flashing in a weird sequence.

I’ve updated my cube to the latest firmware, I’ve tried to use CAN 2 but no results.

Any idea?

Do you have a video of the LEDs?

Does the leds pattern looks like it’s updating? Like this

hi @philip, @Cybra,

Please find the video of the led sequence:

Regarding yours, that looks like a dead module. Open it and check for shorts.

Looks like module is in bootloader. Try updating firmware.

That is correct, please follow the steps to update your module using mission planner, follow the documentation here: Here 4 Manual | CubePilot @cedg507

Hi,

unfortunately when I connect with MP 1.81 If i connect SLCAN then I only see the device with address 127.
I don’t see the here 4.

Any other alternative?

please plug in the other CAN and try again

The lights are totally fine. It always shows like this while it’s updating firmware.

@cedg507 can you try connecting through MAVlink CAN interface instead of SLCAN on DroneCAN panel in Mission Planner. Also make sure you have update Mission Planner to latest beta.

Also make sure all the parameters required for enabling CAN are setup CAN Bus Setup — Copter documentation

Thank you for all your advices, but still no GPS visible…

EDIT: It works … don’t ask me how. All parameters were set properly, I clicked several times on connect disconnect and suddenly I saw it!!

EDIT 2: I still have FMW 1.14.D42

EDIT 3: I am using an old carrier board… I think this one as the issue with CAN1 and CAN2 inverted. So if I am plugged in CAN1 I can see it with all info on CAN2 in MP. If I select CAN1 then I have the ID but question mark for the ID 10 and 125…
