Zumspot / Nextion Driver problem

Zumspot / Nextion Driver issue:
I have a Zumspot RPi hat with firmware 1.4.17 on top of a Raspberry Pi 3, and Pi-Star 3.4.17. All of this has been running flawlessly. I have tried several times to install the Nextion driver to use with my new Nextion 3.5 screen. The Nextion driver installs ok but it "breaks" the Zumspot firmware every time. After a Nextion driver install and a re-boot, my Zumspot is no longer recognized by Pi-Star and the Zumspot firmware has to be re-flashed. Where am I going wrong ?

Why don't you start by using the built-in Nextion support? You only need to install a driver if you want to use Model 8, but that's not needed for basic use of a Nextion display. I run several Nextion 3.5" and 3.2" displays with ZUMspots and have never used Model 8, as I don't need the advanced features Model 8 provides.

Once you get the basic display running successfully, if you want to upgrade to the Model 8 driver, make sure to read this FAQ carefully:

ok, thank you, for some reason I thought must use the Nextion driver. I'll give it a go.

Yes, by broken I mean this....in the logs it says something to the effect of it is unable to Initialize the modem after 6 try’s.
There is no display connected currently. I was only trying to load the driver correctly before attaching the Nextion.

Thank you, I appreciate you. Somehow I missed your step-by-step post when I was doing my original search.

I am able to get the nextion driver to work on a usb adapter but when I try to connect it to the hat it doesn't work. I used 'modem' in the Nextion driver section under advanced.
I have an MMDVM on an Arduino DUE. Is this type of connectivity supported? The pins are there connected to tx3 on the arduino.

Arduino Due has the current firmware.

Am I missing something?

[Nextion]
Port=/dev/ttyNextionDriver
Brightness=50
DisplayClock=1
UTC=0
ScreenLayout=3
IdleBrightness=20

[NextionDriver]
Port=modem
LogLevel=2
DataFilesPath=/usr/local/etc/
GroupsFile=groups.txt
DMRidFile=stripped.csv
removeDim=0
SleepWhenInactive=600

I grabbed the firmware from g4klx's github.

and yup its commented out in config.h

// #define SERIAL_REPEATER

Anything else I should enable from stock firmware?

My guess is the firmware you loaded was built without SERIAL_REPEATER enabled
Enabled SERIAL_REPEATER and now it works. Thanks for that.
