Hiện tại chỉ có các phiên bản phần mềm trả phí và công cụ đắt tiền mới có thể unlock được. Bạn có thể sử dụng DJI battery killer với CP2112 adaptor, nhưng tôi không chắc nó có thể unlock.

oke . Mình đang chờ CP2112 về là vọc

"dji bat Killer" bq9006 not supported yet. I have not yet had this chip in my hands. if you have algorithms for working with this chip, then you can work with it manually using commands and cp2112

I understand . I just want to share a bit of information for anyone looking for scl and sda.

The best is going to be to isolate the STM32 chip from BQ9006, otherwise, STM32 might interfere with EV adapter and BQ9006. Also the STM32 likes to talk even if device is in BOOTMODE :(

You can reset the lock of BMS from a rooted drone.

Is that theoretical or you can actually reset the BMS lock of a DJI FPV battery using a rooted DJI FPV drone?

Good job Michael, I've patched the communication on STM level so it doesn't return PF flag.

It's not a problem for me.

Are there any paid solutions to the problem today?

What is the situation now? How is the BQ9006_DJi_FPV_37WDJ3BCR21124_backup_BatteryKiller files supposed to be used? What is needed to clear PF from a DJI FPV battery? And what's with the rooted DJI FPV that can do this?
