I tried 4 lanes with compute module 3 and driver by 6by9. Works great at 1080p60

Is this HDMI passthrough or coding h.264 at double the speed the encoder is rated for? :o

I call it like this: wpacliProcess.execute("wpa_cli set_network 0 psk '"12345678"'");
It seems that you would need to some escaping of the double quotes within the QProcess statement.

Code: Select all

wpacliProcess.execute("wpa_cli set_network 0 psk '\"12345678\"'");
What about this?

Re: Raspberry Pi 3 Model B + Touch Display = Rainbow Screen

Had troubles getting the Pi 3 to boot at all, kept stopping at the rainbow screen. I first tried a Raspbian Jessie image we burned 3 months ago and it hung. Another customized image we use in development daily also failed in the same way. Very strange since both images boot fine on a 2B board. I do...

Raspberry Pi 3 Model B + Touch Display = Rainbow Screen

I'm trying to get the Pi 3 to work with the official screen for the past couple of hours without any luck. I've started with installing a fresh copy of Raspbian and did update & upgrade over HDMI. Enabled SPI & I2C in raspi-config, disabled overscan, added more GPU memory and even tried rpi-update. ...

Re: Streaming to Youtube and a Raspberry Pi

Not sure if the Tricaster can be configured to be the host of the rtmp stream, but if this is possible, you can easily fetch it with ffmpeg/gstreamer and rebroadcast it to a few places with a...

Re: Raspberry Pi 2 as a Database Server?

It would depend on what amount of traffic are these users going to generate, but from experience I would say that this is possible. Make sure you get a decent SD card to minimise the data I/O bottleneck and I would personally not use storage mediums for the server on any of the USB ports, because th...

When I was initially trying to do a similar job with linking the traffic between eth0 and wlan0 I also tried to bridge them... and it didn't work. First of all, you need to setup the eth0 adapter in /etc/network/interfaces not to be using DHCP, a static configuration should look like iface eth0 inet...

Hello, I've just corrupted the dpkg status file and somehow decided to follow an internet guide to delete all of the files in /var/lib/dpkg/ and follow an apt-get update to regenerate them, but this has been a terrible mistake.

Hey, sorry for the late reply. Thanks for the comments, I have found that Wordpress encodes the curly quotes different to what they should be, which makes the commands fail.

Wireless hotspot and client simultaneously

I was wondering is there anything out there that could use one USB port and contain a chip or two chips that could provide a wireless client connectivity and hotspot broadcasting simultaneously?
Any suggestions would be much appreciated.

Re: can I make PI be like an mobile router?

You could take a look at available MiFi devices, or if you would need it to be hosted on the Pi, you could check up this or this. Or basically search the forum or google on how to make the Pi as a 3G/4G router. :)
