BLHeli32 firmware is designed to run on 32-bit ESC. In this article we will find out what advantages BLHeli32 has and what changes there are. 23 thoughts on “ BLHeli32 ESC Firmware Overview ” Tim 23rd May 2018 at 8:52 am. Or create your own BLHeli32 configuration utility which works on Linux and Mac. Not ant of the BLHeli32 ESCs. To do the firmware upgrade, perform the following steps:- Run BLHeliSuite32 and then read your ESCs to find out what layout firmware they are using.
RPM filtering with BLHeli_S for free
BHeli_S firmware is OpenSource software product. It evolved from BHLeli firmware that was running on the relatively slow Atmel MCU’s. It’s development almost stopped in year 2017, when the devs started a new BLHeli_32 branch with closed source, licensing and etc. BLHeli_32 ESC firmware introduced the so called bidirectional DSHOT protocol that enabled the ESC to send the telemetry to the Flight Controller. That allowed the RPM filtering to be implemented. RPM filtering soon became known as the best filtering option that reduces almost all the vibrations that multirotor motor can induce. The only problem was that the RPM filtering was only possible with BLHeli_32 ESCs.
Luckily, one of the developers, called joelucid, implemented the updated BLHeli_S firmware with optional closed source DSHOT telemetry module. To enable DSHOT rpm telemetry you would need to purchase the license for the optional Telemetry Service. Each ESC requires one license. The JESC firmware can be found here: https://github.com/jflight-public/jesc.
But that was until now when the RCGoups user JazzMaveric implemented the bidirectional DSHOT in the BLHeli_S firmware for free! This means no licenses and no fees needed for the bidirectional DSHOT on almost any BLHeli_S ESC! The modified BLHeli_S firmware repository can be found here: https://github.com/JazzMaverick/BLHeli/tree/JazzMaverick-patch-1/BLHeli_S%20SiLabs
How to flash the BLHeli_S firmware with DSHOT RPM telemetry?
First you’ll need the BLHeli Configurator. You can download it from here: https://github.com/blheli-configurator/blheli-configurator/releases. You can also use the BLHeli Suite (https://www.mediafire.com/folder/dx6kfaasyo24l/BLHeliSuite) to flash the BLHeli_S firmware, but this guide will show the steps with BLHeli Configurator.
Note: Remove your props before connecting the quad to the PC! (unless you have tiny whoop – its small props will make almost no harm 🙂
Note #2: Make sure you have fully charged battery before flashing BLHeli_s firmware. If your battery discharges in the middle of the firmware flashing process you may brick your ESC!
Start the BLHeli Configurator, connect the flight controller to the PC and plug the battery. Press [Connect] and then [Read setup]. You should see all four ESC settings.
Write down the type of the BLHeli_S firmware. The naming of the BLHeli firmware: first letter is the hardware configuration of the ESC, the second letter shows H – for BB2 MCU and L – for BB1 MCU and the last numbers show the Dead Time value.
Blheli 32 Download For Mac
Now open the modified firmware repository https://github.com/JazzMaverick/BLHeli/tree/JazzMaverick-patch-1/BLHeli_S%20SiLabs and select the firmware file with the same naming as you see in the BLHeli Configurator.
After you have selected the right firmware, right click on the button [Raw] and select “Save link as” and save the file.
Next in BLHeli Configurator press the [Flash all] button and then press [Select File Manually]:
Select the downloaded BLHeli_S firmware file (double check the naming!):
Watch how the BLHeli Configurator flashes all 4 your ESCs:
If flashing process ended successfully, then you should see the BLHeli_S firmware number changed in the ESC tab (also you will notice the startup sounds have changed):
Thats it! Now you have BLHeli_s firmware with the bidirectional DSHOT and you can set up the RPM filtering in the Betaflight configurator.

In August 2016, Google announced its intent to discontinue support for Chrome Apps on all platforms other than Chrome OS. The plan was to start discontinuing apps starting in mid-2017 with most apps being completely unusable in early 2018. The driving factor behind this decision was that Chrome apps were “not being used” – Google cited that less than 1% of users have ever installed a Chrome app.
This sucks for the miniquad world – we may very well be the 1% of users Google was talking about. Most of us use at least 3 Chrome apps regularly: Betaflight Configurator, BLHeli Configurator and Blackbox Explorer.
This week it looks like the hammer has dropped. All three apps can no longer be found on the Chrome Store using the built-in search functionality, and we suspect permalinks to them will be going offline shortly. Fortunately, the amazing developers in our community have not been asleep at the wheel – a workaround is available.
Betaflight Configurator and Blackbox Explorer are now available as standalone applications. They can be downloaded from the following locations:
Betaflight Configurator
Betaflight configurator can be run as a standalone application on Windows, Mac and Linux. It can be downloaded from the releases page on Github:
https://github.com/betaflight/betaflight-configurator/releases
Once downloaded, unzip the application somewhere on your computer. There is currently no option to install Betaflight Configurator as a conventional application. You must double click the executable from the unzipped folder to start the app.
Betaflight Blackbox Explorer
Betaflight Blackbox Explorer can be installed as a standalone application installer for Windows and Mac. It can be found under the dist/ directory on Github:
Download the set-up executable for your OS and install as normal. The application can then be started from your OS’ launcher.

BLHeli Configurator
As of 12/11/2017, BLHeli Configurator is not offering a standalone app. If this is not rectified by Google’s closure date for the app store, Windows users can go back to using BLHeliSuite. If an app becomes available, we will post it on this page.
