Has anyone got Arduino jammed due to phone being too close to it? My fully autonomous RC plane crashed after I changed phone/camera's location closer to Arduino. Phone had gps, video camera, 2g (internet traffic) and touch screen on. Phone's back side (screen side) was towards Arduino's PWM side 1 cm away.
I can't think of anything else causing the crash but electromagnetic interference:
- Arduino jammed after 7 minutes of normal flight (SDcard log stopped, controls jammed) PMW's to servos continued fixed to last settings
- Arduino rebooted exactly after phone's video recording stopped (reboot time is logged on SD card)
- everything works now and nothing seems to be broken, no solders loose (how to test if Mega2560 is ok?)
- simple power failure does not explain symptoms, because power failure would stop PWM too and servos would go to extremes causing a dramatic end.
After jamming plane continued flying more or less stable about 5 min and motor kept running at fixed speed. Arduino did not respond to remote calls to switch to manual flight mode, and did not fly autonomously actively either, it just kept giving same PWM signals to servos and motor. After crashing to a tree motor kept running 20 minutes until main battery went dead. After exactly 1 hour phone's video camera stopped, and Arduino's reboot was logged on SD card. At that point main battery was on 5.5-6? volts and Arduino did not stay on but for a couple of seconds.
Anyone had similar problems?
