Tinyhawk 2 esc problem

[Nsanti]

I just received a used tinyhawk 2 and the esc seems to be acting weird. It has the startup tone but no 2 beeps after that. Does anyone have an idea of what could be wrong, or how to fix this? I get fpv video to the goggles but no control, and binding doesn’t work.

Usually if hear the first startup tones those just indicate the ESC/motor connection is good, the last couple tones indicate that it's getting some sort of "valid" signal from the FC. Honestly it kinda sounds like a dud you might want to just look to support for return/replacement. For binding can go into the terminal and use the "bind_rx" command to get the receiver into binding mode as described here:

Bind your SPI receiver via Betaflight CLI

If your receiver is connected via SPI, you don’t need to fumble for the bind button - simply bind from the Betaflight CLI with the bind command.

That said if there's no connection from FC to ESCs for some reason (as indicated by lack of last couple tones) then that might be an issue. If you messed with configuration (or flashed) then would double check the ESC protocol settings in the configuration tab in betaflight.

I was kind of thinking the flight controller might be dead after watching a couple of YouTube videos. When I connect to beta flight the quad has no lights, and the accelerometer is not showing. When I type the command to bind I get an error message. Thanks for your help.
