Radio - Firmware update mode

I have bought a Iris+ and all was going great until last night. I had an issue where the radio signal will get lost in 100m and I wanted to get it to do a bit more distance because the follow me will lose signal so this is what I did.

  1. Go into mission planner and connect the iris+ with the 433mhz radios (Success)
  2. Disconnect (Success)
  3. Go into Initial Setup/Optional Hardware/3DR Radio (Success)
  4. I click on Load Settings (Success, both radios loaded local and remote)
  5. I changed Tx power from 11 to 20 on both and clicked Save Settings (Fail, Do Command Error)
  6. I try to connect the laptop to the iris+ (Failed)
  7. I click upload firmaware (Success)
  8. I opened the Iris+ and plugin the usb to the radio and clicked upload firmware (Success)
  9. I try to connect the laptop to the iris+ (Failed)
  10. The iris+ radio has a solid red light which in your documentation says “Firmware update mode”
  11. I download the 3DR Radio application and try everything from the beginning but no success.

How do I get the radio out of “Firmware update mode”?

Try to update firmware on “RED” unit. If it’ll fail - ask for RMA.

Check step 7, I have tried it. What is RMA?
