GREEN LED - Solid Green indicates Bluetooth is connected.
BLUE LED - Flight controller status light which is controlled by the flight controller firmware.
Only if the flight controller gets bricked , please follow these steps to
re-flash firmware for it:
1. Hold the BOOT button (the only button on the FC), and power to FC at the same time,
then the FC will enter DFU mode.
2. Open the SpeedyBee app, go to the FC Firmware Flashing page, and perform the
Firmware Flashing as prompted.

* Due to the size limitation, there's no 5V output from the
FC to the USB-C module, so you need to power the AIO with
a battery before you connect the AIO flight controller to your
computer with a USB-C cable.

Note: In order to prevent the AIO from being burnt out instantaneous
voltage spikes on powering up, it is strongly recommended to use the
Low ESR capacitor in the package.

You could flash both BLHeli_S and Blue Jay firmware for this ESC.
You need to pulg in the battery to the AIO and then connect a USB
cable between the AIO and your PC. Then flash ESC firmware
(BLHeli_S or Blue Jay) in the following online configurator:
https://esc-configurator.com/
Note: ESC Type should be set as 'J-H-40'.
