While updating to Blue Jay 0.21.0, the connection was lost. After that, I tried reading again, but esc is not recognized. What should I do in this case?

As the title suggests, the connection was lost while updating to Blue Jay 0.21.0. After that, I tried reading again, but esc2 is not recognized. How do I resolve this?

Leave it plugged in for a minute and try to read again. If that does not work, you will have to recover via Arduino and C2 interface: https://stylesuxx.github.io/arduino-c2-flasher/

Have you tried force flashing it by enabling the option to Ignore inappropriate MCU and Layout?
That should work as long as you haven't destroyed the bootloader, but just the firmware, and it has worked for me in the past.
(make sure you select the correct firmware manually, check the other ESCs)

Hi, I have the similar issue. I run updating for all ESC to BlueJay A-X-5 0.21.0 48kHZ after finish only ESC1 was updated to 0.21.0 version and than I run updating again and during second updating, process stuck. After reconnect I found out that ESC1 disappeared from the list. Is there any way to restore esc? My FC is Betafpv [F4 1S 5A AIO ]. Waiting after start (~5min) doesn't help me.(https://betafpv.com/collections/brushless-flight-controller/products/f4-1s-5a-aio-brushless-flight-controller-elrs-2-4g?variant=39968364757126). Logs:

@flatdeh Yours is different, your does not show up as unknown anymore, so flashing by ignoring MCU layout as @WaspFPV suggested will not work.

You'll probably have to recover via C2 interface then.

@stylesuxx Thank you for your quick response. I will try to recover via C2 interface, do you have any additional info about it? Does arduino 2c flasher work with arduino mega 2560?
