BLHeli_32 has been some of the 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 think about 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 have 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 out there as soon as the present inventory runs out, as producers gained’t have the ability to get hold of new licenses. For present ESCs, it’s anticipated that there gained’t be any new BLHeli_32 software program updates.
Impacts on FPV Pilots
Within the brief time period, there isn’t a speedy 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 must nonetheless have the ability to buy them within the subsequent few months, if not longer. Though there gained’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. The truth is, most individuals want flashing their BLHeli_S ESCs to Bluejay anyway.
Methods to inform if in case you have BLHeli32 or BLHeli_S ESC: https://oscarliang.com/identify-esc-firmware/
Producers will ultimately have to change from BLHeli_32 to different ESC firmware. This transition would possibly trigger some disruption within the availability of ESCs, however I believe the affect might 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 coated these within the following tutorials:
What Ought to You Do Now?
In the event you’re presently utilizing BLHeli_32 ESCs, there’s no speedy want to change. 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.
If you’re shopping for new ESCs right this moment, it’s value contemplating AM32 for future-proofing. Though it’s nonetheless okay to purchase BLHeli_32 and swap to AM32 later if you want. Yow will discover ESC with AM32 firmware on AliExpress: https://s.click on.aliexpress.com/e/_Dm32AXj.
For these able to discover AM32, it’s essential to know the method totally. 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 must undoubtedly flash Bluejay because it gives extra options and higher efficiency, significantly 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 big and unlucky change, but it surely’s not the tip 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. Producers and the neighborhood ought to help these open-source initiatives to make sure a easy transition.
Within the meantime, hold flying together with your present gear, keep knowledgeable in regards to the newest developments, and be ready to adapt because the panorama of ESC firmware evolves. The way forward for FPV remains to be shiny, and we have now the assets to navigate this modification efficiently.
