Problem Installing ON7LDS Nextion Driver

Post by wb2lma »

After installing the ON7LDS Nextion Driver using the following commands:

rpi-rw
cd /tmp
sudo wget http://on7lds.net/files/nextion-driver.tgz
sudo service mmdvmhost stop
sudo tar -xvzf nextion-driver.tgz -C /
sudo ./NextionDriver_ConvertConfig /etc/mmdvmhost
sudo service mmdvmhost restart

I then re-booted the Pi

After the reboot I did not find ttyNextionDriver file in /dev

What did I miss in the installation ?

Found this same problem.
Goto folder path: /usr/local/bin
You should there see the file: NextionDriver
Copy this file to your /dev folder renaming the file using this command from the /usr/local/bin folder: sudo cp NextionDriver /dev/ttyNextionDriver
Should then work and show up in your configuration page port drop down list
When you decompress the nextion-driver.tgz file it should have showed you the folder where the NextionDriver file was copied.

I had this same problem. Copying the driver to the /dev folder solved it for me too. Such an easy solution, I wonder why it didn’t happen during installation? Maybe I should have done an “rpi-rw” command before running the install. Anyway, thanks for posting!

PS: Maybe ON7LDS’s new installation script takes care of this. See github.com/on7lds for info on the installation script plus a script that checks the installation afterwards.

Install procedure is changed, see www.github.com/on7lds and select the Nextion Driver helper repository; there's a complete read.me and how to ..

I followed the direction using the installer script file and the Nextion driver was showing in the display confg. Now it isn't and I can't get it to show in the drop down. I have tried reinstalling and I get an error. Here is what happens:

pi-star@pi-star(rw):tmp$ sudo NextionDriverInstaller/check_installation.sh + This seems to be Pi-Star

Searchin MMDVMHost ...

What do I need to do to fix this?

Goto

Configuration
Expert
MMDVMHost
Scroll Down to Nextion
You can erase /dev/ttyUSB0 with back space and type in /dev/ttyNextionDriver.
Apply
should look like the following

Goto
Admin
Power
Reboot
Will show in Configuration drop down after reboot.

Tried to install ON7LDS per the website instruction.

when I typed CD/tmp it said the directory did not exist. what do I do?

I tried to install it anyway and it cause the pi to crash. I could no longer connect to it. I had to re install the image and set everything back up to get it back working. So I don't want to do that again.

I am very new to Linux and the Pi's. I am using a Jumbo Spot MMDVM with a 2.4 Nextion Display. I would like to get this Model 8 working.

73 Thanks, Walter

There needs to be a space between the command and the target. Thus: cd<space>/tmp
