TTY access to Gateway

I første del af vejlingen som jeg linker til er der et afsnit "Retrieve Root Password", her valgte jeg at monterer 3 stk dupoint connector til at forbindelse til TTL-adapteren, de kan blive efter opsætningen, så er de der hvis der kommer nyt software.

Gateway	TTL-adapteren
Serial TX	RX
Serial RX	TX
GND	GND

!! Husk at Serial til TTL adapteren skal være sat til 3,3V

Serial Terminal Settings

Serial_adapteren skal snakke med en tty terminal, her har jeg valgt at bruge Putty for Linux. Med Putty er det nemt at sætte de rigtiǵe indstillinger for samtalen, her er mine valg:

Settings: 
    Windows -> Font -> Font used for ordinary text ->
        Client: Ubuntu Mono 16
    Connection -> Serial ->
        Serial line to connect to: /dev/ttyUSB0
    Configure teh serial line ->
        Speed:          38400
        Data bits:      8
        Stop bits:      1
        Parity:         None
        Flow control:   None
    Session ->
        Saved session:  LidlGateway

Decryptering software for ubuntu 20.04LTS

For at kunne få held med decryptering, skal der instaleres lidt hjælpe værktøjer på min Linux PC, vejledning fundet her:, komandoerne vist herunder:

sudo apt-get install python3.8-dev
pip install pycrypto

Now I clone banksy-git/lidl-gateway-freedom

cd ~/
git clone git@github.com:banksy-git/lidl-gateway-freedom.git

Copy files from script directory to my work direktory:

mkdir ~/lidl-gateway-freedom/SEKT1
cd ~/lidl-gateway-freedom/SEKT1
cp ~/lidl-gateway-freedom/scripts/lidl_auskey_decode.py ./
cp ~/lidl-gateway-freedom/scripts/upgrade_ncp.py ./

Download files for for EZSP upgrade

vi skal bruge 3 filer for upgrade

Make sure the script firmware_upgrade.sh is executable:

chmod +x ./firmware_upgrade.sh

I run into problem after upgrading my Ubuntu from 18.04LTS to 20.04LTS

To get around the problem I did change all SSH command to include an -o option

-o option
    Can be used to give options in the format used in the configuration file.  This is useful for specifying options for
    which there is no separate command-line flag.  For full details of the options listed below, and their possible values,
    see ssh_config(5).

So they came to look like these:

ssh -p2333 -oHostKeyAlgorithms=+ssh-dss root@192.168.0.231
ssh -oHostKeyAlgorithms=+ssh-dss root@192.168.0.231

and the file firmware_upgrade.sh is change, there are 3 line to change:

From:

#!/bin/bash

EZSP_VERSION="$3"

Now to the fun part: Retrieve Root Password

Customise running software on the gateway

This section must be run on Linux or WSL (Or any Bash like shell)

Run from your host PC

SSH into your gateway with the username root and the password you decoded earlier, the SSH server will be running on port 2333 and run the following

Note!! If SSH returns: no matching host key type found. Their offer: ssh-dss

SSH login as root: asrk3w0L

ssh -p2333 -oHostKeyAlgorithms=+ssh-dss root@192.168.0.231

Run when logind to gateway

if [ ! -f /tuya/ssh_monitor.original.sh ]; then cp /tuya/ssh_monitor.sh /tuya/ssh_monitor.original.sh; fi
echo "#!/bin/sh" >/tuya/ssh_monitor.sh
reboot

SSH Port is now change from 2333 to 22

Run from your host PC

Upload new serialgateway.bin

cd ~/Dokumenter/Github/lidl-gateway-freedom/scripts

Åben terminal and run code

cat serialgateway.bin | ssh -oHostKeyAlgorithms=+ssh-dss root@192.168.0.231 "cat >/tuya/serialgateway"

SSH login as root: asrk3w0L

ssh -oHostKeyAlgorithms=+ssh-dss root@192.168.0.231

Run the following on the Gateway

if [ ! -f /tuya/tuya_start.original.sh ]; then cp /tuya/tuya_start.sh /tuya/tuya_start.original.sh; fi

cat >/tuya/tuya_start.sh <<EOF
#!/bin/sh

chmod 755 /tuya/serialgateway

reboot

Upgrade the EZSP Version to 6.7.8.0

This section must be run on Linux or WSL (Or any Bash like shell)

Run from your host PC

chmod +x ./firmware_upgrade.sh

NB!! You may be prompted for the root password several times, when running next script.
