Order Number: UT-697338
Product Name: Darwin129
Brand: Darwin FPV
After flashing my FC I have lost my UART’s and have no idea what number they are in betaflight ports tab
Hi
Please check the darwinFPV site and download their relevant CLI dump file as this can then be loaded onto your FC to restore factory defaults.
However, one word of warning as you should probably only load the ports section of the dump, as the CLI dump they provide is only for BF 4.1.1.

# serial
serial 20 1 115200 57600 0 115200

Otherwise I will reach out to DarwinFPV to see if they have a more recent one, however this may be the only version they provide.

Thank you so much Alex, I’ll look in to how to do that, I’m having these struggles because it’s all advances in the years since
I was using openpilot, I need to learn how to the dump as when I tried to load my saved configuration in betaflight It wont open
Thinking maybe I need to do something with the file like with zipfiles 
not great with computers i’m a welder by trade
Hi Carter,
The typical flashing process nowadays is very different to how it used to be unfortunately - it might be worth watching or reading a guide (for example this from Joshua Bardwell: https://www.youtube.com/watch?v=yGhmtF44OH4) to take you through the process. You shouldn’t need any ZIP files (unless, for example, the board manufacturer provides some settings inside a zip file or similar).
It’s also worth noting that the above guide is for betaflight 4.5 - if you’re using a different version, it’d be better to find a guide for that specific version as the steps differ.
I hope this helps!
Best regards,

Thank you Cameron
I’m slowly getting my head around it
It’s been a learning curve, I’ve managed to reflash with the matek405 clone rather than standard and I’ve got my receivers connected now and everything is looking good
Had to change the pitch to 270 I think it was, all good and corresponding as it should as well as all my stick inputs and movements of the actual match that onscreen model, I copy and pasted just the serial part of the cli dump from original save into the new and save, then checked with another client dump and they are there as should be, I was so chuffed by that
Next I’ll do the motors/esc calibration then I’ll do the modes
Is it really necessary to flash the esc with bluejay or will Dshot do to begin with, I have also used the recommended 7" preset available on betaflight currently
I have watched the JB betaflight walk through and learned a lot from that but I found the rotorriot guys video a lot easier to follow, having two of them explain with the quad set up.and computer, it’s been a while, I was last building quads ordered from China when it was openpilot I guess 7-8 years ago, its come a long way in that time.
Thanks again
Regards Mike
Hi Mike,
Apologies for the delay getting back to you!
I think you may be confusing terms - Dshot is a protocol (The “language” which the FC and ESC use to talk to eachother), whereas BlueJay is a firmware which supports the Dshot “language”.
Most ESC’s will ship with Bl_Heli_S, Bl_Heli_32 or some other firmware. BlueJay is an alternative for ESCs which ship with Bl_heli_S only.
Lots of people recommend BlueJay over Bl_Heli_S as it offers more features, but for the sake of simplicity, it’s not required to flash it - you can just select the Dshot protocol in betaflight and be on your way if you don’t want to mess about with ESC firmware flashing 
I hope this helps!
Best regards,
Cameron
