VESC 75/300 R2 with R1 Firmware

Submitted by frank on Thu, 2019-11-28 09:39

There have been a few VESC 75/R2 (V1.12) sent with R1 firmware installed. The problem ith that firmware is Bluetooth functionality. For Bluetooth and some Comm communication you need the correct R2 Firmware.

The firmware can be found here:

Low-Speed Hall Interpolation Performance Issues

Submitted by cpaterson on Tue, 2026-01-27 03:42

I'm trying to debug an issue I'm having with low electrical/mechanical rotational speed, speed control, running the VESC Labs Maxim 120V model which I believe runs on FW version 6.06. I'm controlling a internal permanent magnet motor, which is running hall sensor based rotor position sensing. The motor has 8 poles. I'm trying to run as low as 10 RPM mechanical, so 40 ERPM on a dynamometer setup.

Measured stator resistance not consistent

Submitted by LoicLL on Wed, 2026-01-21 18:15

I'm currently implementing a custom VESC hardware based on the VESC4 architecture, using a STM32F405 and version 6.06 of the firmware.

I'm encountering an issue with stator resistance measurement. Using the terminal command "measure_res [current]", I've observed that the lower the current target, the higher the stator resistance value, and the higher the current target (still less than 5.0 A), the lower the stator resistance value. Is this expected behavior?

Modifications Needed for Custom Dual Motor ESC for 3S Operation

Submitted by NK-108 on Mon, 2025-12-15 18:27

I am attempting to create a single-board dual motor ESC for use on a small 3S UGV. It's been pretty slow going reverse engineering from the 6.5 schematics and the hw_conf files. My original idea was just to duplicate basically everything and then have them connected to single CAN bus with the vehicle controller, but I just discovered the HAS_DUAL_MOTORS parameter which seems perfect for me application.

Hello,

Sinds the new stable 6.06 firmware my lisp script cannot be uploaded to the device anymore

I'm using an ubox_singel_80 en get this error:

 

Preparing new image...

Parsing 14894 characters

Error: type_error

CTX: 408 "main-u"

Current: i

bound to: 0

In: bufget-u8

Has somebody an idea how I can solve this.

If more info is needed please let me know so I can provide it.

FSESC 75100 Pro V2 W/ ALUMINUM

Submitted by drstein99 on Tue, 2025-08-26 23:02

Hello, I just received the Flipsky VESC, 75100 Pro v2 w/ aluminum case.  I load the VESC software tool on the PC,after correctly loading the usb port driver the software now recognizes the ESC.

The program reports firmware may be out of date.  So I go to the firmware page, just to check.  For reasons unknown, it is reporting that firmware for HW "75_300_R2" is loaded.

Fw: v6.02 (no_hw_limits), Hw: 75_300_R2

1E 00 3D 00 08 51 34 30 37 35 37 39

Paired: false, Status: STABLE

HW Type: VESC, Phase Filters: Yes
