3D print Callsign, 2 colors Yellow and White choose, size
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
Add a WiFi AP sharing on the cell phone or router, let bluebox connet to your AP,
the default WiFi profile in bluebox:
visit the dashboard as follows
http://pi-star.local [iOS shares]
http://pi-star [Android or other]
Login : pi-star
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?
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
Frequency restrictions to avoid satellite interference. Please avoid the following ranges: 145.8-146.0 MHz and 435-438 MHz, otherwise firmware will not start.
