#Impulse rc driver fixer serial
This commonly occurs when you try to connect to your board, or flash firmware and you get an error message saying failed to open serial port. Thank you very much for this tutorial, I had been looking for a solution to my problem for a long time.If you ever have any issues when connecting your STM32 based flight controller to your PC, chances are you are using the wrong drivers for your board. Everything is brand new, this is a first time setup on this quad. It just says connecting for a moment, saying successfully serial port successfuly opened then changes to successfully closed. My FC shows up fine at com5, and I can start the connection. Please give some some advice to fix this. The FC appears to work because it has its green light on, steady. What could be the problem? When I connect the battery it beeps 3 times only, not 5 as it should. So nothing happens!! Hello My flight controller diatone mamba f is not showing any sensor on board after I flashed the firmware with STM32F firmware. Right click on it and click Update Driver Software. There are going to be many options but choose the one that is more likely to be your FC. Run Zadig, choose your flight controller in the drop down list 1. The easiest thing to do is to use Zadigto find it. Note that with SPRF3 boards, you might want to try changing the baud rate to first, maybe that would do the trick. And you should be able to flash the FC from now on without any issues on this computer. Once done, your COM port will reappear in the text box.
