Also attached lsof output. Realized that I have to sudo as root to get the output. 1830 is weewx PID. Looks like 3 threads from weewx as per below this. [image: image.png] On Wed, 29 Apr 2020 at 01:14, 'Rich Altmaier' via weewx-user < weewx-user@googlegroups.com> wrote: > Ah, but that NUC order

will you please stop pushing NUC which is not at all coimparable with an RPI - it is like comparing apples to pears. On Tuesday, 28 April 2020 22:44:37 UTC+3, Rich Altmaier wrote: > > Ah, but that NUC order of magnitude cost is equal to how many hours of Pi > troubleshooting? > Rich > > >

Ah, but that NUC order of magnitude cost is equal to how many hours of Pi troubleshooting? Rich On Tuesday, April 28, 2020 at 7:15:02 AM UTC-7, Tom Keffer wrote: > > A NUC is also an order of magnitude more expensive! > > Andrew's suggestion of an externally powered USB hub is a good one. A g

Re: [weewx-user] Raspberry pi USB disconnects

Or just upgrade to a Pi4. I have had USB issues for years with older Pis, to the point where I have a hub on one of them just to drive a z-wave stick. However, I haven’t had any issues at all with the Pi4, I’m assuming because of the USB hardware redesign on that box. Admittedly, I haven’t had

Re: [weewx-user] Raspberry pi USB disconnects

A NUC is also an order of magnitude more expensive! Andrew's suggestion of an externally powered USB hub is a good one. A good power supply for the RPi is also essential. On Tue, Apr 28, 2020 at 7:12 AM 'Rich Altmaier' via weewx-user < weewx-user@googlegroups.com> wrote: > Praveen, as I have adv

Praveen, as I have advised before, consider upgrading to the Intel NUC. All USB electrical problems gone! Yes it costs more. Yes it is 10-20x faster. Yes it is trouble free! Good luck. Rich -- You received this message because you are subscribed to the Google Groups "weewx-user" group. To unsu

what model pi are you using? are you using a separate powered usb hub or one of the ports on the rpi? On Tuesday, 28 April 2020 07:14:05 UTC+3, Praveen Chandrasekaran wrote: > > Attached output of lsusb. > > I dont see anything in lsof output probably because nothing is using it at > the momen

Re: [weewx-user] Raspberry pi USB disconnects

Attached output of lsusb. I dont see anything in lsof output probably because nothing is using it at the moment (shouldnt weewx be using it continuously in rapidfire mode?) Also can I edit weewx to add lsob whenever the error occurs? On Tue, 28 Apr 2020 at 01:04, Tom Keffer wrote: > Things to

Re: [weewx-user] Raspberry pi USB disconnects

Things to try: 1. Ferrite coils might help, although you are getting a lot more errors than what is normally associated with EMI. 2, Another possibility is that something else is trying to claim /dev/ttyUSB0. For example, modemmanager has been known to do this. To see a list of processes using /

Sorry, just ignore the part of serial/USB. I got confused with different data logger types available. Will attached detailed log in a few minutes. On Mon, 27 Apr 2020 at 22:07, Tom Keffer wrote: > Don't know what you mean by "Mine is a serial port on Vue side." > > "usb issue must be on pi side.

Re: [weewx-user] Raspberry pi USB disconnects

Don't know what you mean by "Mine is a serial port on Vue side." "usb issue must be on pi side." Not sure what you're asking here but, yes, the USB plugs into the pi, and that's where the assignment to /dev occurs. The very short screenshot you included doesn't offer many clues as to the cause.

Re: [weewx-user] Raspberry pi USB disconnects

Thanks. I already hav the udev which is why it auto recovers. Mine is a serial port on Vue side. So the usb issue must be on pi side I assume? Ferrite coil should solve the problem? On Mon, 27 Apr 2020, 21:26 Tom Keffer, wrote: > See the section *Davis cp2101 converter problems >

Oh, and it's possible to save putty sessions. For example, see this web page: https://kerneltalks.com/tips-tricks/how-to-save-putty-session-output-automatically/ Screen shots don't work very well. They save a tiny area, and take a lot of space. On Mon, Apr 27, 2020 at 8:55 AM Tom Keffer wrote:
