Connect to PI-STAR, setup your WiFi config

Quickly start guide

Prepare an IP address scan tools  

http://www.advanced-ip-scanner.com  [for Windows]

https://www.fing.com/  [Fing for iOS/Android]

1  Power on your hotspot ,wait about 30s to startup completed

2  Configute network for your Pi-star,

LAN: 
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.

WiFi Self-AP: 
the first time connect to hotspot
Open the phone, search the WiFi AP "Pi-Star"

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

Reboot.

Login userid : pi-star , 

Password: raspberry 

* This way now just support inner Raspberry Pi Zero, Pi 3B, Pi 3B+, not support USB WiFi NanoPi NEO.

Use default WiFi SSID 
(Suit who buy full set product from BI7JTA)

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

SSID:888888-2G password: 0123456789 , when connected, visit pi-star dashboard  

iOS shares WiFi hot spots: http://pi-star.local

Other devices share WiFi: http://pi-star

Login User: pi-star ,Password :raspberry

Just for reference, SSID set to  888888-2G

The final way, use "Pi-Star WiFi Builder" ,then download and copy to your TFcard root, the method need a TFCard to USB adapter.

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.

Firmware upgrade UserGuide for MMDVM HAT(Simplex/Duplex/Repeater) made by BI7JTA

Important update ,from firmware v1.4.12

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.
tail -100f /var/log/pi-star/MMDVM-2018-11-21.log
Error message Received a NAK to the SET_FREQ command from the modem

NOTE: 
1)  WiFi SSID and PASSWORD BE REPLACE WHEN Restore Configuration!

2) If run firmware upgrade script error ,run Pi-Star OS first  **Important**

sudo pistar-update && sudo pistar-upgrade

Check new firmware

How to enter ssh mode:

http://pi-star:2222/ [Or use IP address]

usr: pi-star

pas: raspberry

1 ) Duplex HAT by BI7JTA VR2VYE

sudo pistar-vyehsflash hs_dual_hat
Radio/Modem Type "MMDVM_HS_Hat Dual Hat(VR2VYE) for Pi(GPIO)"

2)for Nano hotSPOT (BlueBOX)

sudo pistar-vyehsflash nano_hs

change Modem_Type to "MMDVM_HS_NPi Hat (VR2VYE) for Nano Pi(GPIO)"

*For old version HAT,

*If not successful,some old nano HAT need do more operation,connect the upgrade GPIO jumper, detail see here.

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

3)for RPi_Simplex hotspot

sudo pistar-mmdvmhshatflash hs_hat  

Change Modey-Type to "STM32-DVM / MMDVM_HS - Raspberry Pi Hat (GPIO)"

4)for MMDVM repeater board make by jTA

For V3_F446 

Upgrade logs:

20191002: add RSSi data display support

Change Modey-Type to "STM32-DVM / MMDVM_HS - Raspberry Pi Hat (GPIO)"

Open your ssh GUI http://pi-star/admin/expert/ssh_access.php  

User: pi-star  

Pass: raspberry  

Login and Ctrl + C then Ctrl +V ,run the follow scripts   

rpi-rw;  

curl -OL https://raw.githubusercontent.com/bi7jta/MMDVM_HS_firmware_VR2VYE/master/RepeaterV3F4/stm32flashV5;  

sudo chmod +x stm32flashV5;

curl -OL https://raw.githubusercontent.com/bi7jta/MMDVM_HS_firmware_VR2VYE/master/RepeaterV3F4/mmdvm_f4.hex;  

sudo killall MMDVMHost >/dev/null 2>&1 ;  

sudo ./stm32flashV5 -v -w mmdvm_f4.hex  -R  -i 20,-21,21:-20,21 /dev/ttyAMA0;  

#Please Power off then Power on(Not the reboot).  

For V1_F105

*Important* Just support use boot loader flash HAT firmware

The new firmware version is RPT_1.4.7 

New feature: Support POCSAG mode.

Download https://www.bi7jta.org/files/STM32DVM_F105/

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  

https://github.com/N4IRS/MMDVM-Install/blob/master/STM32-DVM/required-libs.sh  

Demo videos :

https://www.youtube.com/playlist?list=PLe3vAuVeEGj-p4WhxvPDDpKf82AYa7e6B

Flash use ST-LINK (Not suggestion)

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

For V3 F446 Version
