Oak unresponsice after flashing attempt with Arduino
« on: April 06, 2016, 08:09:46 am »
My Oak seemed to be connected properly to the Particle Cloud, since I could see the device on the Particle Dashboard, so I attempted the Arduino tutorial (I'm running the Arduino IDE ver 1.6.8). During the flashing process the IDE told me that the flashing failed, and now the Oak doesn't respond. The PWR LED is lit, but the P1 LED isn't flashing any more. I also can't see the device's SSID, so I can't reflash the firmware.

Any ideas? I guess I may have to buy a USB-serial converter and try to reflash via serial connection, but I'd like to avoid that. Disconnecting and reconnecting power have no effect.

Try this looking for Safe Mode: =safe&s[]=mode]http://digistump.com/wiki/oak/tutorials/arduino?s[]=safe&s[]=mode

Note: You can force the Oak into safe mode to receive uploads even if something is failing by holding Pin 1 low during boot.

Put a wire to ground on power-up and remove that after 5 seconds then look for the AP on WiFi if it doesn't connect to the your WiFi and show as ready to program.

@jcverive: When you say wouldn't respond - it wasn't active on the Particle dashboard and wouldn't respond to another request to program? And also try defragsters suggestion - unless the Oak is completely bricked as is need of a firmware overwrite, it should come back up for programming in safe mode. You connect Pin 1 to GND, connect the Oak to power, and remove the Pin 1 / GND connection after approx 2 seconds. The P1 LED should then be doing a constant triple blink pattern to indicate it is in safe mode - where you can either configure the wireless, or reprogram the oak. You can then try to program the Oak again.
