Quickly start guide to connect MMDVM network

Quickly start guide
1  Plug in the power supply , require 5V2A(RPi 3B), 5V1A(RPi Zero W)

2  Configute network for your Pi-star,

Way 1th: if there is a LAN port in NanoPi or RPi, insert RJ45 line, the routers automatically allocate the IP address, use a computer browser (must use Firefox or Chrome) to access the IP address, set up your personal information.

Way 2th: open the phone, search the WiFi "hotspot Pi-Star-setup" then join it , password is "raspberry" , use mobile browser ,visit http://192.168.50.1,  add the WiFi you need in the WiFi setup column (and add a WiFi principle to your new cell phone). * This way now just support inner WiFi adapter,not support USB WiFi.

Way 3th: Add a shared WiFi on the cell phone or router, the default access WiFi:

SSID:888888-2G password: 0123456789 ,visit the dashboard as follows
iOS shares WiFi hot spots: http://pi-star.local
Other devices share WiFi: http://pi-star
Login User: pi-star ,Password :raspberry

If the domain name can not be identified, use IP tool APP like “FING” to find the IP address of the box.

3 Configute your digital radio
The default setting frequency is 433.550MHz, DMR mode, time slot 2, color code 1, and DMRid 4600000
Private call to  9990 ,use parrot mode for echo test.

How to do
1) login ssh mode:
http://pi-star/admin/expert/ssh_access.php
default
usr: pi-star
pas: raspberry

Copy the follow RED text ,then Ctrl+V, and press ENTER,
Notice that rpi-rw, sudo su , su pi-star, just support one line one time

#2) Change system to Read and Write
rpi-rw

#3) Install require runtime
sudo su; 
rpi-rw; 
cd /tmp;
git clone https://github.com/pyserial/pyserial.git;
cd pyserial;
python setup.py install;

#When install  runtime complete,change to pi-star user
su pi-star
cd /home/pi-star

#Download nextion.py
wget https://raw.githubusercontent.com/g4klx/MMDVMHost/master/Nextion_G4KLX/nextion.py

#4)Download Nextion firmware to current directory
#for 4.3 inch NX4827T043
wget https://github.com/nano-mmdvm/Duplex_hotSPOT/raw/master/nextion/NX4827T043_G4KLX_ShowIP_by_BI7JTA.tft

#for 3.2 inch NX4024T032
wget https://github.com/nano-mmdvm/Duplex_hotSPOT/raw/master/nextion/NX4024T032_G4KLX_ShowIP_by_BI7JTA.tft

Firmware upgrade UserGuide for MMDVM HAT made by BI7JTA


1 ) Duplex hotSPOT by BI7JTA VR2VYE

Original from
https://github.com/VR2VYE/MMDVM_HS_firmware/releases
https://github.com/juribeparada/MMDVM_HS/releases

The lastest Version is 1.4.4 when update this guide,the newest you can find in github.

There are 3 ways to upgrade,
Make sure you has choose Radio/Modem Type "STM32-DVM/ MMDVM_HS-Raspberry Pi Hat(GPIO)"



How to enter ssh mode:
http://pi-star:2222/
default
usr: pi-star
pas: raspberry


1) Use inner upgrade tools in Pi-Star OS

Use official version, build by G4KLX
sudo pistar-mmdvmhshatflash hs_dual_hat

Use VR2VYE build version
rpi-rw
#take ver 1.4.8 for example, the newest version visit github
wget https://github.com/VR2VYE/MMDVM_HS_firmware/releases/download/v1.4.8/mmdvm_duplex_fw.bin

sudo pistar-mmdvmhshatflash-custom mmdvm_duplex_fw.bin 

2) Manual execute upgrade, this way support downgrade version.

Use BI7JTA & VR2VYE build version
https://github.com/VR2VYE/MMDVM_HS_firmware/releases
Or
Use Andy CA6JAU Version
https://github.com/juribeparada/MMDVM_HS/releases

#1) login ssh mode:
http://pi-star:2222/
default
usr: pi-star
pas: raspberry

Copy all follow text ,then Ctrl+V, and press ENTER

#2) Change system to Read and Write
rpi-rw
cd ~

#3) Download flash script , take  version 1.4.4 for example
#View the last version available here 
https://github.com/VR2VYE/MMDVM_HS_firmware/releases 
or
https://github.com/juribeparada/MMDVM_HS/releases
curl -OL https://github.com/VR2VYE/MMDVM_HS_firmware/releases/download/v1.4.4/install_fw_duplex.sh

#4) make runable
sudo chmod +x install_fw_duplex.sh

#5) Stop MMDVMHost serice
sudo pistar-watchdog.service stop; sudo systemctl stop mmdvmhost.timer; sudo systemctl stop mmdvmhost.service

#6) Flash to lastest version
./install_fw_duplex.sh

#7) Startup MMDVMHost service
sudo pistar-watchdog.service start; sudo systemctl start mmdvmhost.timer; sudo systemctl start mmdvmhost.service



2 ) Nano hotSPOT (Bluebox)

sudo pistar-nanohsflash nano_hs
If not successful,some old nano HAT need do more operation,connect the upgrade GPIO jumper.

https://github.com/nano-mmdvm/MMDVM_HS_firmware/blob/master/how-to-upgrade-nano-hs-fw.md



3)for RPi_Simplex_hotspot  && hotSPOT in LCD make by jTA

sudo pistar-mmdvmhshatflash hs_hat  



4)for MMDVM repeater board make by jTA


Update: This firmware is compiled by BI7JTA, use source code from G4KLX 20180822, synchronize with duplex hotspot Ver 1.4.7 

New feature: Support POCSAG mode.


Flash use USB 
Suggest this way,enter flash mode easy then GPIO
1)Use USB mode  
1.1 Disconnect STM32-DVM from the RPi host, GPIO and USB all disconnect,  
1.2 Insert JP jumper, short BOOT and VCC near P25 LED,  
1.3 Connect STM32-DVM to the RPi host use USB wire, then will endter flash mode automatic. PWR, ACT and DMR will bright, not flashing (Very important,if not as I description, disconnect USB and connect again) .  
1.4 Flash use USB (replace your .hex path, and download stm32flash,see Require libs )  
sudo stm32flash -w /usr/src/MMDVM/bin/mmdvm.hex -v /dev/ttyUSB0  
  
Require libs  

Video Playlist :





Flash use ST-LINK
Buy a ST-Link ,then connect to the board ST-LINK interface, then open STM32 ST-LINK Utility, choose mmdvm.hex,then flash.
