Pager Feature && instruction

PLL or crystal, 137-199 MHz and 400-499 MHz, POCSAG.

Please notice that the frequency you use.

*One device just with 4MHz bandwidth.
*The frequency can be customized in the frequency range, 4MHz bandwidth you can program when come out factory.

For example, your order 1x 439.9875MHz, you just can use 437.9875-441.9875 MHz.
You can not use 458.6625MHz when you customize 439.9875MHz.

*Default frequency is 439.9875MHz.

Warning

Q&A

1) You can use the default RIC id if can not write your ID, the first and the second have Beep Beep voice,

2) Some language Character coding not support in DAPNET server, will cause unintelligible text, change to English is ok.

3) Some time DAPNET server connect timeout, try later or change network(WiFi).

Flash Nextion Firmware update 2020

Nextion firmware (Model8)

Model8 requirement

Pi-Star 4.1.2 and update to the last

MMDVM Display Type: Nextion Layout:ON7LDS L3,

Nextion-editor ,to change your display style

https://nextion.itead.cc/resources/download/nextion-editor/

Format tools:

https://www.bi7jta.org/files/PiStarTools/SDFormatterv4.zip

Download

1. Local , output for Nextion T serial (4MHz memory), clone from PD0DIB

https://www.bi7jta.org/files/MMDVM_Nextion/

2. PD0DIB homepage, you can modify use editor
https://github.com/PD0DIB/Nextion_HAM-radio-screens

2. G4KLX, the original project

https://github.com/g4klx/MMDVMHost/tree/master/Nextion_G4KLX

Note: HMI file you need to install Nextion Editor, general the tft bin file.

Flash firmware use SD card (TFcard)

Youtube demo: https://www.youtube.com/watch?v=cPOL8UedAGA

How to output different Model tft file?

What is the difference between Nextion and TJC?

Detail: https://www.bi7jta.org/shop/duplex-hotspot-model-a-3d-white-5inch-33

If you not edit/Develop the display content yourself , TJC is enough for use, but use Nextion Model, you will find more resource in Facebook group https://www.facebook.com/groups/Nextion.

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

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
