About Me:
I'm a software developer and I am trying to learn about electronics, EE & other interesting stuff by building a UAV.
Please tell us a bit about your UAV interest
I'm in it for the technical challenge. I've also always been interested in robotics and the field is really impressive at the moment so I want to get into it and learn all of the technical stuff.

"I ended up getting a 3.3V FTDI USB-to-TTL to replace my PL2303. This resolved the issue where the update would freeze at 2%."
"No problem, Jesse. Driving an RC transmitter with a joystick sounds like a good idea, but why an ARM processor? Just curious since I haven't looked into this approach myself."
"Thank you, Rana and Noth666!
I have done testing for 30m-1hr periods with a grounded UAV and it was able to preserve the link. If the signal is lost both the GCS and the UAV will begin to send out ping requests to each other at short intervals. If…"

"Jesse, I will add a diagram for a test circuit. Thank you for asking!"
"Thank you, Alberto!I found a post somewhere on DIYDrones stating that their testing had shown that the Xbees work best at 57600 baud, did you try different baud rates in your project?Still, I haven't had a chance to fly very far with mine. I'm…"
I started this project as an attempt to reduce the amount and cost of hardware required to control a UAV. Since many UAVs already have a radio modem as their telemetry link, I wanted to try piggybacking a control link over the radio modem instead of…
"Hi Cameron & Sandro.
I can't comment on the voltage levels for the TX/RX pins, but it sounds like communication is working in both directions for you.
If the TX pin is disconnected you won't get the ID in the software. If you disconnect the RX…"

"I am having the same issue as you, Scott. I am using a Prolific (pl2303) USB-to-TTL. I cannot invert the signal in software so I used a spare hex inverter to handle this. I'm getting the same results: the UID shows up but the firmware load does…"
