THANK YOU!!!THANK YOU!!! THANK YOU!!! I've looked all over for info on why my screen was missing info in the fields and you nailed it with the the ssh stuff (I thought I was going to brick the hotspot the entire time I was in the session!) I get really intimidated when I haft to type those commands in! This video was perfect straight to the point with no BS!
Thank you very much for your excellent video!! It has been VERY frustrating trying to get my Nextion screen working properly with all data fields populated as they should be. I have a MMDVM_DUPLEX hotspot and my Nextion screen is connected directly to the MMDVM. I wasn't sure your instructions would work as I was not using a USB connection. However, they did indeed work. For the benefit of others with a similar setup as mine I would suggest: 1. Follow the instructions in the video very carefully. Your screen should be working with basic information displayed before you begin the driver installation. 2. Make sure the settings under [Nextion] are exactly the same as shown in the video. I had to change my screen layout to 4. 3. For a hotspot which has the Nextion screen connected directly to the MMDVM board, under the [NextionDriver] section you will need to set your Port to "modem". 4. On the configuration page, make sure you have "Nextion", "/dev/ttyNextionDriver", and "ON7LDS L3 HS" selected. Hope this helps! 73
good advise but... the converter I buy one does not work and is very different show this video and I still can't use my Nextion Screen even follow this steps. I try to search the one show here but Not founded.
Excellent video on adding Nextion screens to MMDVM. I am new to this hotspot concept. I have a working MMDVM hotspot with an OLED screen. Can you please confirm if I can add an external USB to serial converter and a Nextion screen on the Pi Zero W usb port without removing the existing OLED screen? I do not want to remove or touch the internals of the hotspot as its working perfectly... Please share your thoughts.
Thanks for the demo, on that last screen with the yellow, I have the similar one for the nx3224T but im not able to get the remains data to work through the modem port, any advice? I cant seem to find any info on why
I thought I would share something that plagued me. The nextion driver script sudo guesses at the port the nextion is connected to. If you don't do anything, it assumes /dev/ttyAMA0. But you normally connect it to the modem port. So instead of /dev/ttyAMA0, it needs to be modem. Just make sure your screen is working with modem selected under Port. Once it is working, then install the driver, and the nextion driver script will know it's connected to modem.
I must be missing something here...my display worked (minus the info fields like CPU etc.) before I installed the driver. Now it just sits on the boot screen and never loads. I've triple checked the settings. I'm wondering if it's a USB/port issue.
Does anyone know if this will work with other sizes, specifically the 5" (or larger) sizes? The display model I'm looking at is NX8048T050, which is a 5" display, but I can't seem to find any drivers or related information from anyone who has successfully used it as a DMR hotspot display. Do you mind sharing which hotspot you're using as well? I purchased one from Amazon (that comes with the metal case) some time ago, but it doesn't look like the one you have, probably because it has the tiny 0.9" OLED screen on it already. Would I have to de-solder that?
I created a timer on the screen that runs 12 times a day But when I disconnect the power, I have to set the times for the timer again Is there a way to store the timer on the screen even if the power is disconnected?
If the HotSpot already has a small OLED display attached to it and I'm using a USB-UART converter, will the 2 displays conflict or are both able to operate independently? In Pi-Star there is only one possibility for a screen.
@@TechMindsOfficial Indeed, when the Nextion screen would be installed, I would not need the other OLED screen. On the other hand, when I'm on the go, I only bring the hotspot and the screen would stay at home. I don't want to have to reconfigure Pi-star every time and I can't remove the OLED screen temporarily since it's soldered on. So if I select Nextion screen in Pi-Star then it will disable the soldered OLED screen on the hotspot and transfer the information to the Nextion?
Hi Thank you for a nice presentation using the Nextion display in a PiStar setup. Be aware of the Chinese clones - they unfortunately doesn't work. Best regards Bjarke / OZ2BKK
Thank you, I have heard of Chinese clones but I also heard that NO One use them with MMDVM. I would always recommend the original for this project. Thanks 🙏
There is another company that produces HMI screens for the Chinese market, they are almost identical to the Nextion screens, but can only be programmed using their own software that is entirely in Chinese, with no alternative language option. They might be able to understand the same serial instructions from MMDVM's but it would be near impossible to program them without knowing Chinese and spending a lot of time (and money) to try it. It's just not worth bothering.
I know this might sound too stupid but 😅 how to get free SDRs? The country where I live, here 1 usd = 200 rupees and there a hackRF costs around 100000😅😅
dont know about free but maybe look into a rtlsdr which is based on the rtl28xx chip. Should at least be cheaper then a hackrf and ok less features then hackrf but still great fun. the rtl sdr is basically a dvb tv dongle which can be used to receive all kinds of rf singles.. or if your really good with electronics build your own like the websdr guys from university of twente did

Thanks very much for this! I've never had a large display on my board. Very well presented!
You’re welcome Ronny! Thanks for watching 🙏

Where do you get the MMDVM board from as original, I can't seem to find them amongst all these clones online.
very well. thanks had a had time setting up my Nextion till your video.
Awesome vid Matt ;)

imagine my surprise to see my mate Garry (ZC4GR) callsign popup at the start of this video :)
Great Video btw Which Nextion screen file did you use for this demo?
Hi, where did you get that last layout from? Cheers, Phil G8PJH

Is there a way to store the timer on the screen even if the power is disconnected?
thank you
If you accidentally delete the HMI file on your computer is there any way of extracting it off the Nextion display?
If the HotSpot already has a small OLED display attached to it and I'm using a USB-UART converter, will the 2 displays conflict or are both able to operate independently? In Pi-Star there is only one possibility for a screen.
I guess you wouldn’t need both, so you just select the Nextion screen within PiStar

Just doing this now well I've bought all the stuff now watch this video and see what I have to do
So slick!
Sadly RaspberryPi is currently at unicorn status.
Never had much luck wit it.
ta7esc thank you
