Re: How to avoid 2min delay for direct ethernet cable setup?

Yes, the following configuration in /etc/network/interfaces allowed me to do that (no need to plug in a cable to avoid the delay): auto wlan0 auto eth0 auto lo iface lo inet loopback iface eth0 inet static address 192.168.2.2 netmask 255.255.255.0 network 192.168.2.0 allow-hotplug wlan0 iface wlan0 ...

Re: How to avoid 2min delay for direct ethernet cable setup?

Remove anything you changed in the FAT partition
Not sure what to do with this statement. The rest worked like a charm. I assume that I was basically missing the 'auto lo'.

Thank you.

How to avoid 2min delay for direct ethernet cable setup?

I am using a direct ethernet cable as a fallback option to be able to administer the RPi. There is no dhcp server, both sides have static ips. The delay occurs, when there is no cable connected. At the moment, I have the ip address for the RPi hardcoded at the end of /boot/cmdline.txt dwc_otg.lpm_en...

Re: Can't connect to wireless with space in ssid

Over the weekend, I was able to connect to one network with a space in the SSID. It took lots of trial and errors, mostly because the old linksys befw11s4 apparently doesn't support DHCP and WEP (it's old) at the same time (so it is unsecured at the moment). I also couldn't easily find an example wi...

Re: Can't connect to wireless with space in ssid

Thanks, I will try the wpa_gui app over the weekend. Ultimately, I would like to just ssh in, either through direct ethernet cable (which works with hard coded ip address), or via wireless where known and added. The former is to add wireless networks in locations where I won't have a monitor connect...

Re: Can't connect to wireless with space in ssid

After removal and reboot, still no success story (I had the no-space-ssids wrapped in " as well and they worked). Any other diagnostic steps I could take to get to the bottom of this? Any other tools aside from wicd_curses, which fails dramatically, when using 'connect'?

Can't connect to wireless with space in ssid

I've read posts about problems with spaces in SSID, including those that suggest quotes, yet none of my attempts were successful so far. Other networks work fine. The use case requires to be able to easily connect to a variety of networks. Is a space in the SSID possible using wpa_supplicant.conf? ....

Re: Reading serial data from external device (rs232 db9 port

Thanks - this is very helpful. One more question. In case I need a null modem to connect to the device - I know very little about the nature of the rs232 connector on the external device, except that it is female - can I adjust this at the gpio by switching rx/tx or do I need to have an actual null ...

Reading serial data from external device (rs232 db9 port)?

The plan is to use a Raspberry Pi B+ and an USB RS232 converter (e.g., http://www.amazon.com/TRENDnet-RS-232-Serial-Converter-TU-S9/dp/B0007T27H8/ref=sr_1_1?s=pc&ie=UTF8&qid=1411772774&sr=1-1&keywords=usb+2.0+rs232+converter ) After some research there are a few open questions that I hope to get ans...
