I just finished soldering the vTX and receiver on the new flight controller and configured it in betaflight. When I plugged it in to the battery the flight controller had a solid blue light but also a beeping flashing red light. I looked it up everywhere and could not find a solution. On the video showing what is supposed to happen, the red light flashes but does not constantly beep. i am sure it is a simple solution but I don't know how it fix it.
Edit: Ok turns out that the vTX and receiver are not even receiving power...
