Oh I’m not really upset with Darwin per se because of the receiver. There were no instructions as to which target to flash. Like I said originally, on the webpage that opens when activating the WiFi on the receiver, it initially said to flash a BetFPV target. Then after that it said to use a DYI target. It was after I tried that target that the LED went solid and I haven’t been able to do anything with it since. When I try BF passthrough it says “Could not open com port 3, the port doesn’t exist” I have tried manually telling it to use that port and I’ve tried it without naming a port to use and it gives me the same error each time. When I try to use the FTDI adapter the error message says, “Please specify upload port or choose global”. I have no clue what that means. And I do have telemetry off in Betaflight.

What I meant about being upset with Darwin is that I didn’t get a battery that I ordered. It does seem that this receiver is harder than other to bind. I tried bridging the two pads identified earlier and nothing happens. I know they won’t do anything about the receiver. I wasn’t expecting them to. I think it would be really helpful if they simply sent which target to use with the receiver. I don’t know why that 10.0.0.1 address originally told me to use a BetaFPV target then later it said to use a DYI one. 

Shouldn’t the receiver still put itself into WiFi mode after being powered on and not binding with a transmitter within 60 seconds or so? I’m new to this hobby, especially ELRS so I’m just trying to understand how I could have avoided this problem and to prevent it in the future.

When I’ve accidentally flashed the wrong firmware to a receiver, or had an interrupted flash, it no longer goes into WiFi mode no matter how long I wait.

Those errors both make me think you might have a conflict or configuration issue on your computer, or that you don’t have the right drivers installed- but I wouldn’t know where to tell you to start to fix that, my computer knowledge is a couple decades out of date.

I’d still suggest jumping on the discord, but if you post a screenshot of the ELRS configurator with it set up as you had it trying to flash via ftdi adapter, maybe v22 or I can tell you if you need to change something.

Edit- when you’re connecting your ftdi adapter to the receiver, you are remembering to connect rx to tx and tx to rx, yeah?

V22 was very helpful. We tried all sorts of things with no luck. I’d be happy to send the receiver to someone to see if he can flash. I did load new drivers on my computer because I thought that it could be causing the problems. I had the right connections, Tx to Rx and Rx to Tx.

My new Happymodel Rx showed up and it flashed great and I even flew the quad around briefly. The Discord is a pretty cool thing. The people on there are great and were always willing to help out. Thanks again for the link and invite!!

This did seem to be a hardware issue with the receiver. Even attempting to flash directly with a FTDI was failing due to too much noise on the serial UART. There have been several people on the ELRS Discord having trouble with these as well.

It's really disappointing to see DarwinFPV ship such poor quality knockoff-of-a-knockoff receivers, especially when the ELRS devs provide free assistance to manufacturers with hardware design and configuration. I don't understand why more manufacturers don't take advantage of it, as it would save them a ton of support requests and save their users many headaches.

I'm glad things are working well with the new HappyModel RX though. Happy flying!
