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.
- Go into mission planner and connect the iris+ with the 433mhz radios (Success)
- Disconnect (Success)
- Go into Initial Setup/Optional Hardware/3DR Radio (Success)
- I click on Load Settings (Success, both radios loaded local and remote)
- I changed Tx power from 11 to 20 on both and clicked Save Settings (Fail, Do Command Error)
- I try to connect the laptop to the iris+ (Failed)
- I click upload firmaware (Success)
- I opened the Iris+ and plugin the usb to the radio and clicked upload firmware (Success)
- I try to connect the laptop to the iris+ (Failed)
- The iris+ radio has a solid red light which in your documentation says “Firmware update mode”
- 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”?
