I like Nextion screens, but I personally don't think they're necessary. I have a few around that I test with, but, for example, I could never be bothered to try out the Model 8 driver. One thing I know with my own setups is that when I was testing using a Nextion with the standard driver plugged into the serial/modem through-holes on a ZUMspot, it worked when I selected ON7LDS L2, but it didn't work when I selected ON7LDS L3. I'm unsure if there has been some new update since then that would make using ON7LDS L3 work when the Nextion is plugged into the modem port on the ZUMspot (or maybe it's just requires different HMI/tft files?). Hopefully, they'll actually test things and verify that their PDF settings work for their customers.
Yeah, personally I like it better than having a dashboard running all the time cluttering up my chrome tabs.

G4KLX and ON7LDS L2 will work with no nextion driver installed, the only big difference is ON7LDS L2 will send font size and color changes, and Talker Alias info while G4KLX's won't.

ON7LDS L3 requires the Nextion Driver.

You get some useful extra features by using the Nextion Driver that you are missing out on though, like CPU temp. Personally I use it for my custom screen that displays all of the callers information in radioid's dmr database, but I also run a custom version of the Nextion driver too, to be able to get that information correctly. Theres only a few cases when it messes up that I need to tweak still.

So it works, but I'm still annoyed about the splash screen issue. The working screen shows my call sign, the splash screen does not.
Well, I'm glad its working.

Can you take a photo and post it of what you are describing? Sometimes it takes quite a few seconds for the data to populate when the different pages are redrawn. If its been setting there for 5 minutes on the idle screen, and doesn't display the callsign info, then theres a serious issue with the programming on the screen, and there isn't anything you can really do about it since HRO doesn't provide information to the screen info that is preloaded. It looks like one of PD0DIB's screens, but maybe they modified something in it for their package. You'd have to contact HRO or ZUM Radio and ask them.

It sounds like you need to design your own Nextion screen. Some resources to get you started:
Good lord man, thats not an easy task. XD.

Well, dang. I'll download PD0DIB's screen and see if I can see anything wrong with how its programmed, but like I said ZUM Radio could of modified it.

I don't have a 2.4 to test it with, but I do have a 3.5 handy.

Question, do you feel like you could take the hotspot all apart and insert a small SD card into the board the screen is connected too? Cause if so we can reprogram it.

Welp, as I suspected ZUM Radio has modified the software preloaded on the screen, and I don't see anywhere that they make it publicly downloadable, so I can't dissect it and see what its doing/not doing.

But they added that grey box that I assume is setup for T0 text field (which PD0DIB's screen doesn't have), and removed the frequencies and inserted a MMDVM graphic on the DMR page.

These are PD0DIB's screens in the nextion editor software

Maybe KE0FHS can use his contacts and get access to that file/information.

Rene, K1RDD, I think your best bet would be to either download PD0DIB's files and use the Itead Nextion editor to install them to the Nextion screen or accept things the way they are.

If you want to have fun and actually learn how Nextion screens work (and not just accept what is preloaded by someone else), then I gave all the necessary links in the previous post. Start with the good document that Rob wrote, which explains how to do things:
https://github.com/PD0DIB/Nextion_HAM-r ... _v2.03.pdf
That is what I did. I'm a non-technical person and I was able to figure it out, so I think just about anyone can. It took me awhile to figure it all out, but I found it quite satisfying once I did.

Rene or Jason, KE7FNS, if you want to contact ZUM Radio, you can find the email for Jim, KI6ZUM, on QRZ.

But if he does that then he for sure won't be seeing his callsign on the idle screen, but at least it won't be an empty grey box anymore.

Part of me wonders if ZUM Radio is installing the Nextion Driver on their image, and it needs to be configured completely different, cause it should be sending that data to that field when its set to G4KLX or ON7LDS L2, but they could have the screen programmed differently, and its waiting for a click S0 to populate.

If you were able to figure it all out, I'd say you are above average tech wise, and you have a way above average tolerance to being frustrated, cause that documentation isn't very well documented.

I don't really feel like contacting that guy about it, I just assumed from your previous posts and that your website is listed in their instructions, you had some sort of elevated contact than what a random person has.

He can open the downloaded file in the Itead Nextion Editor and add his callsign. That's fairly simple to do.

No, I don't have any special relationship with ZUM Radio. Jim did email me at one point to ask if HRO could link to the instructions on the ZUMspot page. I told him what I tell everyone who asks something similar, which is, sure, as long as an attribution is made in accordance with the terms of the Creative Commons license that I share all my Amateur Radio Notes content under (the Creative Commons Attribution-ShareAlike 4.0 International License). Other than that, I simply a customer like anyone else who buys a ZUMspot board.

FYI, I purposely maintain an independence from all the companies and people I write about so that I can share my honest opinions. I buy all the equipment I write about through normal retail channels, and I pay for all the costs of hosting amateurradionotes.com out of my own pocket. (I even paid full price for Pi-Star! ;)

I spent part of my career working as a technical writer. Even though I'm not a developer and don't know how to code, I really enjoy the challenge of figuring things out. I also have loved writing all of my life, which is why I do what I do; it's simply a fun hobby for me.

XD, yeah I guess so, I really didn't think of it that way, I was thinking more of what is involved to make it dynamic and to work for any callsign.

Well, the documentation you have is really good and well written, so it shows, I know when I was just starting with pistar I stumbled onto your website pretty quickly.

While that sounds intriguing, I'm about 20 years past my programming heyday. Maybe if all else fails and I have some time to delve into it.

I've contacted both HRO and Zum. HRO said it was a Zum support question. We shall see.

Response from KI6ZUM -

We are hearing a few people seeing this including people who are just using displays they have purchased on their own. The best we can guess at the moment is that the Nextion code in mmdvmhost is not checking the return code from the display so it is just assuming that any information sent to the display arrives correctly. It seems like when too much info is sent to the display in a row, the display just throws some of it away. There are a couple of people working on it at the moment.

When I met with Jonathan a couple of weeks ago. he agreed that the whole OLED/Nextion code needs to be rewritten to deal with a whole bunch of problems.
