Nano Pi Firmware upgrade instructions

Linux or macOS Download the script (*.sh) that matches with your ZUMspot/MMDVM_HS board:

install_fw_duplex.sh :Adapted to the duplex board

install_fw_nanohs_for_rpi.sh :Only adapted to nano_hotSPOT for raspberry pi

cd ~

curl -OL https://raw.github.com/VR2VYE/fw_nanohs_for_rpi/master/install_fw_nanohs_for_rpi.sh

make the script executable:

chmod +x install_fw_nanohs_for_rpi.sh

If you are using Pi-Star, stop services:

sudo pistar-watchdog.service stop

sudo systemctl stop mmdvmhost.timer

sudo systemctl stop mmdvmhost.service

stop your MMDVMHost process and run (you will need the root password):

./install_fw_nanohs_for_rpi.sh

and wait to complete the upgrading process.

In this article: MMDVM Hotspot Wi-Fi Configuration, Call Sign DMRID Configuration, Hotspot GPIO Definitions, Some Considerations Used, and Some Extensions.

Setup #1 - The first step connected to the wired network, modify the call sign

Setup #2 - The second step to set up wireless Wi-Fi, wireless use

Setup #2 - The second step to set up wireless Wi-Fi, wireless use

Setup #2 - The second step to set up wireless Wi-Fi, wireless use

Strongly recommend the first method, the lowest cost! If you intend to use the network cable, this step please ignore

Method 1: Insert the network interface directly and wait for the router to assign IP. LAN access http: // pi-star to enter the Web page configuration, as shown in Figure Note: After the configuration is completed, refresh the current page, if you see the WiFi Configuration Bar ) Can display the IP address, then normal, or reconfigure, until you see, pay attention to WiFi ID and password input is case sensitive

Precautions

Precautions

Correct use of Nano hot plate position:

1. Insert, unplug the GPIO socket force evenly, gently shake out, if necessary, with a small screwdriver jacking
2. Plug the first off power, do not live operation
3. Multi-use soft-shutdown: http://pi-star/admin/power.php, SD card directly pull the electric injury
4. Try not to pull NanoPi's MicroUSB interface, plug the USB plug to power off
5. Before formatting the system brush the disk, or OLED will Huaping
6. Try to use a mode of work (DMR / YSF / DSTSR / P25), a variety of modes will have to switch 20 seconds delay, and not controllable

Setup #1 - The first step connected to the wired network, modify the call sign

The first step connected to the wired network, modify the call sign

The OLED display will not light until it is connected to the MMDVM web server, so be sure to complete this step 

Connect to the network cable, power, and other network card flashing green, visit http: // pi-star on any computer, click the [configuration] in the upper right corner, enter the user: pi-star Password: raspberry 

Highly recommended to use Chrome or Firefox browser, other browser problems Firefox address: http://www.firefox.com.cn/download/

Description: As the Nano + large screen raspberry pie 0 does not have network cable interface, you need to use the computer to write WiFi configuration to the SD card, please prepare a TF card reader, refer to the following WiFi configuration method two. If you do not understand the operation, please note WiFi ID and password when ordering, it is strongly recommended to set their own!

For the case of inaccessibility, in most cases the browser has done a domain name to the external network to go, please use Chrome or Firefox. Or use http: // MMDVM hotspot IP address / direct access. There are two ways to get an IP address:

1 Log in to the router to check the terminal of the network cable and check the IP address of the device named pi-star

2 Use the [Auxiliary Tools] on the back of the article to view the IP address of the device named pi-star and start to configure the call sign and DMR-ID.
Here, I set the default DMR and YSF two modes, to facilitate testing, please only keep one and your hand the same model

MMDVM (Multi-Mode Digital Voice Modem) Getting Started

Setup #4 - The fourth step test, start QSO

Setup #4 - The fourth step test, start QSO

Yaesu: By default 00325 TW YSF886 C4FM Taiwan Room, use standard communication for QSO!
DMR: The default connection server for Australia, the channel handsets to 46001 group, tap the PTT into the session, listen, and then the QSO.
 
Parrot Test: Aim to Test Your Echo Yaesu: pi-star Settings Screen Select 00001 - Parrot -Protrot, press the PTT test (there is actually no echo)
 
DMR: Handset add group 99900, transferred to this channel, press the PTT (echo test, but in fact there is no echo, you can go up to shout, the two are not in the same hot HAM can enter each other QSO)

Listen to a group of QSO online
