Wifi dual band 5ghz

I need to connect RPI3 over dual band WiFi (5ghz, not supported by the on-board chip). Is there a way to disable the on-board chip so that a third party dual band WiFi dongle will appear as wlan0?

Re: Eocean on Pi3/Jessie

I think the reason I don't get a creation when the rocker switch is activated is because the device type ESRPU is not included in the HFEM installation.

So, how do we add device types?

Enocean on Pi3/Jessie

Using RPi3\/Raspbian/Jessie, am trying to get enocean working. FHEM installed ok and browser interface on port 8083 looks good. My 'Enocean Pi' doesn't work at all.... fhem doesn't create the device. But my 'USB 300U' at least gets created -- i see the device in the browser. Problem: when I actuate ...

launching application (browser) on boot

In the past. working with RPI2, Ive successfully launched applications on boot by adding entries in /etc/xdg/lxsession/LXDE-pi/autostart. But now, working with RPI3 and the new Raspbian release, I can't get this to work. I've tried several browsers, but that is not the problem -- won't even launch t...

Do you refer to the display or are you referring to RPi OS (SD Card) becoming corrupted? My application includes battery backup with safe shutdown on power loss.

Re: Industrial application w/ Touch

Before committing to an industrial application, I would advise thoroughly testing by power cycling the system several hundred times to see if it consistently comes up running. My own tests have failed on three systems and am waiting for an update to either the hw or sw.

Re: Display testing

UPDATE: Touch lockup only occurring on one of the three systems under test -- suspecting a hardware issue. Other probems previously re-ported occurring on all three systems.

In addition to above issues, the touch capability locks up after a few days of running. The display is fine. Rebooting does not fix Touch, only a power cycle fixes it.

Re: Display testing

You say 5% is that across all devices (i.e. are you finding that any device fails 5% of the time, in which case I should be able to reproduce the problem here) Gordon To be accurate, we re-ran the test. Our text procedure is to repeatedly reboot. Each time, we make sure we see a cursor and then tes...

Display testing

We have three systems under test in our laboratory, all behave similarly, eliminating any hardware problems. For the most part, once the display/touch is up and running it never seems to fail. However, on reboot (and reboot with power) the touch occasionally (5%?) fails -- display is ok. On rare occ...

Re: .net/mono exception: Bad file descriptor

I have found what may be causing this, although I would welcome other comments.. The app scans serial ports (/dev/ttyUSB0,1...) looking for a device, and if there is any attempt to open a serial port that does not exist, the system eventually faults with the error posted. My fix was to do File.exist...
