I'm trying to get the 3DR telemerty radios configured for the 1st time.
But I can't get the radios talking to each other.
My situation:
2.5 APM with latest firmware
APM powered via PSB & ESC, APM LED's red = flashing, blue = on, GPS/red = on
MP set to Com12, 57600 baud
3DR home/usb radio with latest firmware, radio flashed red & green during update
Win 7 x64 Device Manager shows driver installed correctly per FTDI installation/troubleshooting .pdf (see attached)
However, when I use 3DRRadio config 0.9 application > Terminal > ATI = no response from the home/usb radio.... no response from the radio with other AT commands
3DR home/usb radio flashes green
3DR remote radio flashes alternate green & red
Ctrl+A radio configuration displays home/usb radio default config (save worked ok)
no config values display from the remote radio
When I try to 'Connect' I get the countdoun screen which when it reaches 0, it locks up MP, The only way to exit is to Windoes > Task Manager > end task
What does 'Copy required items to remote" do? when do I use this button?
What's my next troubleshooting step to get the radios talking to one another?

Follow the steps below for Linux/Ubuntu to configure Telemetry radio settings (almost all today use SIK firmware):
1) Install Putty (sudo apt-get install putty)
2) Insert the telemetry device to PC over USB
3) Open Putty and configure (look under Session and Connection->Serial sections) :
Baud rate/Speed: 57600
Serial port/line: /dev/ttyUSB0 (check using ls /dev/tty* on terminal)
Data bits: 8
Stop bits: 1
Parity: None
Flow control: XON/XOFF
4) Click Open button
5) An empty serial terminal is shown
6) Type +++ on terminal and press enter
7) You would see "OK"
8) Type ATI5 to show all user settable EEPROM parameters
Perhaps the most useful command is ‘ATI5’ which displays all user settable EEPROM parameters. That will produce a report like this:
9) Now test with the following commands:
The AT commands available are:
All of these commands, except for ATO, may be used on a connected remote radio by replacing ‘AT’ with ‘RT’.
Hope this helps "someone" trying to figure out how this works! Basically its super simple and you can do this over coffee!!

It seems one of your radios is temporarily bricked and you need to flash a new bootloader on to it. I cant recall the exact colors of the LED, but if they are both on they should both be solid green. I think the fact one is alternating between red and green tells us you might need to flash the bootloader for it. If you look around theres a page that tells you how to do this. The procedure involves you shorting two points on the board, and then powering up the radio. Once there you can upload the bootloader and new firmware.
I had a similar problem way back and once i did that everything just worked. The annoying part was getting past the first hurdle.
