BLHeli_32 has been one of the crucial widespread ESC firmware choices utilized in FPV drones. Sadly, it’s been abruptly shut down, and there gained’t be any extra new BLHeli_32 ESCs or software program updates. So, what does this imply for FPV pilots, and what steps do you have to contemplate subsequent? Let’s delve into the small print.

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 not too long ago 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 accessible as soon as the present inventory runs out, as producers gained’t have the ability to receive new licenses.
Impacts on FPV Pilots
Within the brief time period, there isn’t any 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 you need to nonetheless have the ability to buy them within the subsequent few months not less than. Though there may not be new BLHeli_32 updates sooner or later, your ESC will proceed to work as they did.
Notice that this incident solely impacts the closed-source BLHeli_32, not BLHeli_S which is open supply. inform when you have BLHeli32 or BLHeli_S ESC: https://oscarliang.com/identify-esc-firmware/
Producers will finally have to change from BLHeli_32 to different ESC firmware. This transition may trigger some disruption within the availability of ESCs, however I believe the impression will probably be minimal. Time will inform.
ESC Firmware 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 virtually 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 lined these within the following tutorials:
What Ought to You Do Now?
In the event you’re at the moment utilizing BLHeli_32 ESCs, there’s no quick want to change. Your ESCs will proceed to work as they did. 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 choice.
In case you are shopping for new ESCs at present, it’s price contemplating AM32 for future-proofing, or go together with BLHeli_S ESC so you possibly can flash Bluejay. It’s nonetheless okay to purchase BLHeli_32 and swap to AM32 later if you want. You’ll find ESC with AM32 firmware right here:
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 modifications. I’ve a tutorial right here: https://oscarliang.com/am32-esc-firmware-an-open-source-alternative-to-blheli32/
For BLHeli_S customers, you need to positively flash Bluejay because it affords extra options and higher efficiency, notably bidirectional DShot and RPM filtering. Right here’s easy methods to flash bluejay: https://oscarliang.com/bluejay-blheli-s/
Conclusion
The discontinuation of BLHeli_32 is a major and unlucky change, nevertheless it’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 have now the instruments to proceed flying and having fun with the passion. Within the meantime, maintain flying along with your present gear, keep knowledgeable in regards to the newest developments, and be ready to adapt because the panorama of ESC firmware evolves.
