Try this:
cd /tmp
cd /tmp
Ok those do not work through the Modem. That says all I need to know.WU0V wrote: ↑Thu Nov 29, 2018 7:41 pm Walter, when you say you don’t get the full function, do you mean—for example—that the reboot and shutdown buttons don’t do anything? If that’s the case, it’s because connecting via the modem connection won’t work for those functions. I had to change over to USB for those to work. There’s supposed to be an upgrade of the Model 8 screens sometime in the future that may allow those buttons to work via the modem connection.
I have my J-Spot/Pi 0 W/Nextion 3.5 setup connected through the USB port now (originally had it through the modem port); the onscreen buttons work now, and I get CPU load, temp, CPU speed, etc. onscreen. The only function that doesn’t work is Disk Free, it just shows “??”
Here’s something to check. SSH in as you did to install the driver.
cd /dev
ls (this will display a list of all the files in the /dev folder)
look for a file named ttyNextionDriver
If it’s not there that might be the problem. To put it there, while still SSH-ed in, do this—
rpi-rw
sudo cp /usr/local/bin/NextionDriver /dev/ttyNextionDriver
(This copies and renames the nextion driver to the /dev folder)
sudo reboot now (reboots so the newly copied driver is picked up by the config function)
If it’s there and you still don’t get it working I can share the config and expert settings I used to get mine working via USB if you want them. You’ll need a USB to TTL converter in that case—I think mine was $6.
Also, I’ve been assuming your Pi-Star system and dashboard are the latest versions and that your Jumbospot firmware is at least V1.4.8 (1.4.12 is current). If those aren’t recent, the Nextion driver needs them updated.
