I purchased the Gremlin a few months ago and built it to TJ's exact specs. After the build was done I hooked the board up to Betaflight and it connected right up. I just recently picked up the new Spektrum FPV Racing Serial Receiver and just today got that all ready to go. I bound my DX8 to the Gremlin and went all through the setup in Betaflight that TJ did. No issues there! When I had to change my motor direction I installed BLheli Suite32_32608. The software installed and no errors or issues. I hooked the cord to the flight controller and attempted to connect to BLHeli. The only avaliable ports are COM1 and COM3 (STMicroelectronics Virtual COM port. At first it connected just fine but would not read the ESC's. I would get a box displaying 4 ESC format found but all the ESC's were blank. AS I continued working with it I started getting COM port 3 errors. Now I get an info box that jumps up asking for me to Please connect ESC and power up (cycle Power) which has a bar that continually moves back and forth across the screen. Have you guys ran into this issue before? I am a heli guy and this is really my first multirotor that I have ever messed with that was built and configured. Any information you can provide for me to try or test would be great.
