MMDVM nanopi pistar hotspot setup GUIDE:

connect RJ45 cable to hotspot,power up with 5V 2A Phone Charge
to ensure and check OLED left LED Flash(not green one) it Mean the RF board
Running if not repower again
wait 1 minutes the same router computer open http://pi-star
mac open http://pi-star.local

login:pi-star pass:raspberry
http://pi-star/admin/configure.php
Radio/Modem Type:
set Modem: STM32-DVM-(Pi Hat)GPIO then Save
MMDVM Display Type:
then select OLED then Save
reselect Modem :STM32-DVM-(Pi Hat)GPIO then save
you can see the OLED on
open http://pi-star/admin/expert/edit_mmdvmhost.php
OLED Scroll set 1
Apply Changes

the base setting is ok,you can select your Digital Mode now
if every thing work well pls don't update the pi-star

FAQ:
Q:the OLED didn't Work?
A:Check the RF board the LED need flash 1s on/off,repower to let it work.
Q:the hotspot DMR didn't work?
A:go to admin live log download the log file to see what happed.

OSTAR is open source now.

OSTAR MMDVM Suit test on MT7688 wifi Module and youku yk1 MT7620 router running DMR/P25/YSF/DSTAR/NXDN/Pocsage Service
the same as pistar but simplify rom is only 8M build in travelmate module support add muiti wifi SSID and auto connect
any openwrt router have>= 16M ROM and have USB port MT76x8 have 3 uart so don't need usb ,buy MT7620 need USB to connect USB MMDVM Hotspot
i make a raspberry pi zero or zero w image for test the image is only 18Mb
to use openGD77 usb serial select kernel module-usb kmod-usb-atm/acm kmod-usb-serial kmod-usb2
