Headless Access Point Mode
#1
Hi,

I am trying to setup open plotter headless mode with an AP but I seem stuck any advice would be appreciated.

RPI 2
OpenPlotter 0.8 (Checksum is ok)
Write image to SD card with dd
load up boot drive
edit config.txt with;
- device=wlan0, SSID , password etc
Boot up and no AP appears

To troubleshoot:
- connect serial cable
- boot is normal, login as pi and sudo to root
- ifconfig shows wlan0 without ip address
- lsusbĀ Bus 001 Device 004: ID 148f:5370 Ralink Technology, Corp. RT5370 Wireless Adapter

so I figure better check my work, go to /boot/ and check config.txt i note everything i have changed is there except it just has "device=" no wlan0

so I use nano (with sudo) and edit it again, close, open it again and check changes are present reboot and get the same result.

For a laugh I copy config.txt to config.txt2 and reboot and I can see both files. config.txt2 is good and config.txt has changed again.

I am sure I am doing something stupid but I can't figure it out.

Any help would be appreciated.

Cheers,
Alex

strange behavior.

Activate AP editing boot/config.txt with default values. Run openplotter, connect by serial and type


Code:
nano /home/pi/.config/openplotter/openplotter.conf


if the section [WIFI] contains the correct values, type


Code:
sudo python /home/pi/.config/openplotter/wifi_server.py 1


Any error?
