BLHeli_32 has been one of the vital standard 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 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 just lately determined to close down its enterprise operations (see the above screenshot of their assertion for particulars). This implies BLHeli_32 ESCs will not be obtainable as soon as the present inventory runs out, as producers gained’t be capable 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 is no such thing as a fast 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 be capable 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.
Be aware 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.
How you can inform you probably have BLHeli32 or BLHeli_S ESC: https://oscarliang.com/identify-esc-firmware/
Producers will ultimately have to modify from BLHeli_32 to various ESC firmware. This transition would possibly trigger some disruption within the availability of ESCs, however I feel the affect might 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 may be 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?
When you’re at present utilizing BLHeli_32 ESCs, there’s no fast 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 resolution.
If you’re shopping for new ESCs right now, 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 grasp 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 presents extra options and higher efficiency, notably bidirectional DShot and RPM filtering. Right here’s methods to flash bluejay: https://oscarliang.com/bluejay-blheli-s/
Conclusion
The discontinuation of BLHeli_32 is a major 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 group is resilient and adaptable. With options like Bluejay and AM32, we’ve the instruments to proceed flying and having fun with the interest. Producers and the group ought to assist these open-source initiatives to make sure a clean transition.
Within the meantime, preserve 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 continues to be vibrant, and we’ve the sources to navigate this transformation efficiently.
