Problem with BLDC and Firmware 3.55

Hello, 

I'm using the Vesc 4.12 Hardware. I also added an NRF based BLE to stream real time data to my phone. The vesc mobile App said I have to update the Firmware to 3.55 if i want to use the tool with full access, so I update the Vesc to 3.55. Now BLE connection ist also stable and I get real time data to my phone. But from now I can't use motor detection and the red LED is flashing. For a test I downgraded the firmware and everything worked, but not the BLE connection with full access to motor config, realtime data, ... 

 

Does someone have the same problem or do you have any ideas to fix that? 

Thank You!

Hi,

I also had the same problem. And some more people as well: https://www.reddit.com/r/ElectricSkateboarding/comments/bjmeyp/problem_vesc_412_blinks_red_after_firmware_update/

The error I had was something related to "High Offset Current Sensor 2".

Short solution: run FOC motor detection and the error should clear. This fixed the error for me, however it returned after a reboot and don't feel like running the VESC tool every time I power up my board.

"Definitive" solution: downgrade the firmware on the VESC. Run VESC tool version 1.08 or lower and perform a firmware flash. That should fix your problem.
It would be neat if anybody out there could provide a download link to VESC tool 1.08 since I don't have it!

I found this problem too. It is fixed in FW3.56 and VESC Tool 1.10. Sorry about the inconvenience.

I solved the problem by switching over to the Ackmaniac ESC tool.

Oh I just found this, it was my fault writing that code that only worked in FOC mode, BLDC mode is not my forte. I'll cover those use cases next time, I'm sorry about that.

If issues like that get reported in github I'll jump in right away.
