I think it was a Cloud problem, because it's working right now.
Thanks.

It would help if you included the error message you got.

@fossette Very well written!

I have a serious serial I/O problem that has me baffled. I just picked up on a tidbit in your final paragraph. In reference to the first Omega serial port it is at a 3.3V level. That is no surprise as the device runs at 3.3V. However, this may be at the core of my problem.

I'm getting garbage from the device over the serial port. In the first case I used a breadboard expansion to a serial-to-USB converter. I highly suspect the Omega could not drive the converter adequately as the breadboard signals are true device signals, and the converter was overdriving the Omega serial receiver. On the Omega I connected to both serial ports with the same effect, to no surprise.

In the second example, garbage abounds as well. However an expansion dock is in use and is powered up by 5V only being connected to Tx1 and Rx1. Bi-directional garbage. Is this interface also at 3.3V?

I'd appreciate a reply. FYI, here are my next steps. Somewhere, somewhere, somewhere in the docs find what these interfaces are spec'd at. Put a scope on the Tx1 port to check signal level and quality.

Here's another data point which points to a drive level issue. In one test config I have a sensor device driving the Omega Rx1 twice a second with perhaps 60 characters each message. Only a small percentage of the characters get through at random times, and are unrecognizable.

thanks!

Douglas, thank you for your reply. You are correct, I can see small traces from the connector to the holes for the first 2 rows!
I didn't know about that, so thanks again!

@Adem-AVCU
The message exit status 1 error compiling seems to indicate an issue compiling your arduino code.

Are you using the Onion Arduino Library, and if so, have you downloaded and installed it?
Note that for Arduino Dock 2, there's no need to use the Onion Library or the Onion object. Try getting rid of that and trying again.

So, apparently I solved the issue with the opkg (didn't update, I downloaded the .ipk package from the repo and installed manually).
I solved the OpenSSL, now I'm struggling with another module (Twisted). LOL

Thank you so much anyway!

@Orrin-Woodard said in Trouble running command "python oledNewsFlash.py" for project News Flash Headlines:

... any other ideas?

This is the original oledNewsFlash.py by thepiper (James Liu)
I've made some simple modifications. download

It's very frequent on "hacker-news" ;-)

On certain "source" : "bbc-news" ("cnn", "google-news", ...) you should use the "sortBy" : "top" parameter instead of "sortBy" : "latest".

config.json { "X-API-KEY" : "your valid API key", "source" : "cnn", "sortBy" : "top" }

I haven't got any Oled Expansion - so any feedback would be nice. :-)

Thank you,

I read that discussion months ago.
The last message was 5 months ago.
It's only 'issue need to be fixed', 'somebody has temporary testing fixing lib'...etc.
There is no official fix or update from Onion.
I don't think it's a solution for normal users.

@György-Farkas
Thank you, but clearing the cache doesn't help. PuTTY's SSH solving the problem :)

Just to close the loop in case anyone else finds this.

I found it worked using the standard location, ~/.ssh/authorized_keys.

I used puttygen (Windows) to create the key and pasted it in there.

There is a dropbearkey program that will let you create keys on the Omega2+ in case you want to ssh FROM the Omega2+ to, say GitHub/Gitlab...

@Chaim-Krause Seconded

I am still having a very similar problem with my arduino dock and have not resolved it as yet:

https://community.onion.io/topic/2177/arduino-dock-error/

Maybe one of the comments given will help you figure it out. If you do please let me know how! :)

I'm using

curl 7.52.1 (mipsel-openwrt-linux-gnu) libcurl/7.52.1 mbedTLS/2.5.1 Protocols: file ftp ftps http https Features: IPv6 Largefile SSL

from Onion's repo. Same problem :(

upd:
Fixed by

opkg install http://downloads.lede-project.org/snapshots/packages/mipsel_24kc/base/curl_7.54.1-1_mipsel_24kc.ipk opkg install http://downloads.lede-project.org/snapshots/packages/mipsel_24kc/base/libcurl_7.54.1-1_mipsel_24kc.ipk

hologram sent me an email about using their network. i have 2 particle electrons so they must have gotten my address from that forum or somebody mined my address as a probably interested. i did not buy the device they pushed on ks so i don't know what you were promised but what they have is very similar to particle electron device except they have 4G and electron is limited to 3g.

I don't know if you are still awaiting replies to this post from April.
Maybe you've already tried your idea and either melted the relay, or not.

Having just messed up badly with something like this myself, I urge you to be VERY CONSERVATIVE with how much current you switch with an electromagnetic relay.

Also, use an ohmmeter to measure the off-resistance of the heater you wish to switch. I don't know about heater coils, but incandescent bulbs have very low off resistance -- leading to very high turn-on currents -- that need to be taken into account when controlling them with relays.

Another approach is to control a solid state relay (of more than sufficient capacity) with your micro-controlled relay. The downside is you then have to provide the power to that loop. These things are often quite cheap and durable.

Good luck!
