4PIN show "LCD", pi-star Config MMDVM Display Type select Nextion -> Modem HS RXD to Nextion TX HS TXD to Nextion RX HS 5V to Nextion 5V HS GND to Nextion GND
for Ver1.0.1( !! VCC,GND not same as Ver1.0)
Pi-Star Setting display type
2. Use USB to TTL adapter,
then in pi-star Config MMDVM Display Type select Nextion -> /dev/ttyUSB0
Note: Some USB2TTL adapt not work, had tested CP2102 / CH340 is OK, USB-STC-ISP do not work. TTL RXD to Nextion TX TTL TXD to Nextion RX TTL 5V to Nextion 5V TTL GND to Nextion GND
For RPi hotSPOT with fan
1 Use board 4 PINs Display interface, follow the order.
Warning! Can Not Reversal 5V and GND！
2 Use USBtoTTL Adapter
For Repeater kit board
Just can use USBtoTTL Adapter, STM32F105 without serial interface
Still not solved your problem, not config success, then send me 3 files for analysis, as follow,
1) Pi-star config zip file, export step
2) Screenshot of pi-star ,1,2,3
3) Screenshot of DMR radio (reference to tyt md-380)
4) More shot video can help analysis fast.
to:
1. Use facebook user discuss group.
https://www.facebook.com/groups/nano.mmdvm/
Strongly suggest that because of the UTC difference, I hope more HAMs can help you, not only me, also need you upload some shot videos about your issue ,that will faster to discover your problem.
If you need,just send reply this blog or contact my other email bi7jta@gmail.com , leave your Callsign for print, and email for contact. I let my friend place a link in market, use a cheaper shipping channel .
3D print Callsign, 2 colors Yellow and White choose, size
Quickly start
1 Plug in the power supply , require 5V2A
2 Configute network for your Pi-star,
Method 1th, LAN interface (Recommand)
> Insert RJ45 cable to NanoPi LAN port, the other end connects to your router ,
> Reboot your bluebox, wait the OLED bright, just bright when network and modem initialization complete,
> Find the IP Address use APP "Fing", the hostname "pi-star", then visit http://IP Address or http://pi-star
> Add WiFi config for Pi-Star, Modify your profile in setting page
Method 2th
Add a WiFi AP sharing on the cell phone or router, let bluebox connet to your AP,
the default WiFi profile in bluebox:
SSID:888888-2G
password: 0123456789
visit the dashboard as follows
http://pi-star.local [iOS shares]
http://pi-star [Android or other]
Login : pi-star
Pass :raspberry
Note:
Not all device support use domain name visit, use IP Address is a best choose,
Do not use IE browser!
3 Configute your digital radio (DMR mode for example)
The default setting frequency in Pi-Star is 433.550MHz, DMR mode, time slot 2, color code 1,
You can send a private call to 9990 or TG4000, get a response voice for echo test.
How to upgrade pi-star?

user: pi-star,
pass: raspberry rpi-rw sudo pistar-update && sudo pistar-upgrade How to upgrade firmware?
from pi-star ver3.4.11, use command line as sudo pistar-nanohsflash nano_hs sudo pistar-mmdvmhshatflash hs_dual_hat #for duplex_hotspot make by jTA sudo pistar-mmdvmhshatflash hs_hat #for RPi_Simplex_hotspot make by jTA If not successful,some old nano HAT need do more operation,connect the upgrade GPIO jumper.
Flash Pi-Star OS http://www.pistar.uk/downloads/ select NanoPi imagePi-Star_NanoPi_V_XXX-May-20XX.zip Abjust RXOffSet TXOffSet if BER large then 1%
Nano hotSPOT OffSet default is 0 or 200,abjust +-50 to low BER
