BLHeli_32 has been one of the common ESC firmware choices utilized in FPV drones. Sadly, it’s been abruptly shut down, and there received’t be any extra new BLHeli_32 ESCs or software program updates. So, what does this imply for FPV pilots, and what steps must you think about subsequent? Let’s delve into the main points.

Why is BLHeli_32 Shutting Down?
BLHeli_32 has been the go-to firmware for 32-bit ESCs in FPV drones. Initially, BLHeli and BLHeli_S had been open-source, however BLHeli_32 was closed-source, owned by the Norwegian firm BLHeli AS. ESC producers needed to buy a license to make use of BLHeli_32 firmware on their ESCs.
Nevertheless, BLHeli AS lately determined to close down its enterprise operations (see the above screenshot of their assertion for particulars). This implies BLHeli_32 ESCs will now not be out there as soon as the present inventory runs out, as producers received’t have the ability to receive new licenses. For present ESCs, it’s anticipated that there received’t be any new BLHeli_32 software program updates.
Impacts on FPV Pilots
Within the quick time period, there is no such thing as a quick want to fret for FPV pilots. Will there be a scarcity of ESCs? Personally, I don’t suppose so. There’s a good quantity of present BLHeli_32 ESC inventory, so it’s best to nonetheless have the ability to buy them within the subsequent few months, if not longer. Though there received’t be any new BLHeli_32 updates, your drones will proceed to fly as they’re.
Notice that this incident solely impacts the closed-source BLHeli_32, not BLHeli_S, because it’s open supply. In truth, most individuals desire flashing their BLHeli_S ESCs to Bluejay anyway.

Producers will ultimately have to modify from BLHeli_32 to different ESC firmware. This transition would possibly trigger some disruption within the availability of ESCs, however I believe the affect will probably be minimal. Time will inform.
ESC Firmware Alternate options
There are already viable ESC firmware options. For BLHeli_S, there’s Bluejay, and for BLHeli_32, there’s AM32. These firmware choices can ship nearly the identical performance and efficiency, if no more.
When switching to a brand new ESC firmware, the flashing and updating course of will change too. I’ve coated these within the following tutorials:
What Ought to You Do Now?
For those who’re at the moment utilizing BLHeli_32 ESCs, there’s no quick want to modify. Your ESCs will proceed to work as they’re. Don’t rush into flashing AM32 as a result of there’s no actual profit, and when you flash AM32, there’s no going again to BLHeli32. It’s higher to attend and see how the state of affairs evolves after which make an knowledgeable determination.
In case you are shopping for new ESCs right now, it’s price contemplating AM32 for future-proofing. Though it’s nonetheless okay to purchase BLHeli_32 and change to AM32 later if you want. You could find ESC with AM32 firmware on AliExpress: https://s.click on.aliexpress.com/e/_Dm32AXj.
For these able to discover AM32, it’s essential to grasp the method completely. Take time to analysis and guarantee compatibility earlier than making any adjustments. I’ve a tutorial right here: https://oscarliang.com/am32-esc-firmware-an-open-source-alternative-to-blheli32/
For BLHeli_S customers, it’s best to undoubtedly flash Bluejay because it gives extra options and higher efficiency, significantly bidirectional DShot and RPM filtering. Right here’s the best way to flash bluejay: https://oscarliang.com/bluejay-blheli-s/
Conclusion
The discontinuation of BLHeli_32 is a big and unlucky change, but it surely’s not the top of the world for FPV pilots. Whereas there could also be some short-term disruptions, the FPV neighborhood is resilient and adaptable. With options like Bluejay and AM32, we’ve got the instruments to proceed flying and having fun with the pastime. Producers and the neighborhood ought to assist these open-source tasks to make sure a easy transition.
Within the meantime, maintain flying along with your present gear, keep knowledgeable concerning the newest developments, and be ready to adapt because the panorama of ESC firmware evolves. The way forward for FPV continues to be shiny, and we’ve got the sources to navigate this alteration efficiently.
