2023-06-09 DMRGateway-5 Created
This is a clone of DMRGateway-4 with one (at this time) added feature
For DMRGateway setup instructions see the DMRGateway-4 posting at
https://tgifnetwork.createaforum.com/new-board/brand-new-dmrgateway-4/

Reminder: This DMRGateway version was developed to add the filtering that is missing in the pi-star version and to provide a method to handle 7 digit talk groups
This version adds filtering to lock a network such that none of the other networks will bleed through to the radio and
stop the hotspot from arbitrarily switching talk groups based on network activity and
stop the hotspot from going into tx mode from an unwanted network activity thus missing activity on the tg the radio is tuned to.(ie: Busy light - no audio)

A new parameter   RawNet   was added to /etc/dmrgateway in the [General] section
if RawNet=0 the DMRGateway-5 will act exactly like DMRGateway-4
if RawNet=1 to 6 then the designated net will be handled as Raw Mode regardless of whether or not you are running the rest of the DMRGateway in 7 Digit or 8 Digit Mode.

ie:
Assuming Net4=TGIF and Net5=MNET and GWMode=8
if Rawmode=4,  then
31665 will put you on Net 4 TGIF 31665   (Raw Mode)
15031665 will put you on Net 5 MNET 31665 (8 Digit Mode)

if GWMode=7 then
5031665 will put you on Net 5 MNET 31665 (8 Digit Mode)

INSTALLATION
New
sudo git clone https://github.com/ve3rd/DMRGateway-5

Update
cd /home/pi-star/DMRGateway/git pull

Run the following from the DMRGateway-5 Directory'
rpi-rw
sudo su
make clean
git pull
make
make install
./GWConfig.sh


Menu for the DMRGateway configuration script (GWConfig)

   1 "Create/Edit the DMRGateway Password File"
   2 "Install DMRGateway & Update /etc/dmrgateway - Basic Mode"
        3 "Select Network for Raw/Basic Mode 0-6 (default=0)
   4 "Install DMRGateway & Update /etc/dmrgateway - 8 Digit Translation Mode"
        5 "Install DMRGateway & Update /etc/dmrgateway - 7 Digit Translation Mode"
        6 "Install DMRGateway NO Config File Update"
        7 "Restore Original DMRGateway Binary File"
        8  "Quit")

  BASIC INSTRUCTIONS
   
  Item 1:
   This will create and/or edit a password file. (Required for a new Install)
   This is used to enable desired networks and allow an off line repository for
   the Network security codes. This is mandatory for a new install.
   
  Item 2, 3 and 4 Common:
   This will overwrite the /etc/dmrgateway file with a default version and
   will compile a new Binary if required and
   will install the New Binary DMRGateway File
   
  Item 2
   will proceed with a limited configuration Using Basic Mode
   In the Radio CPS use basic 31665 for 31665 on the Server
   Key on Tg 9001 to 9006 to select Network 1 to 6
   This will allow the use of 7 digit talk groups
   
 Item 3
   will select a network that will run in basic mode. A zero will default to no network in basic mode.
   If selected this network will handle 7 digit talk groups.

  Item 4
   will proceed with a limited configuration Using 8 Digit Translation Mode
   In the Radio CPS use 14031665 for TG 31665 on Network 4 etc.
   This will allow the use of 7 digit talk groups.
   
  Item 5
   will proceed with a limited configuration Using 7 Digit Translation Mode
   In the Radio CPS use 4031665 for TG 31665 on Network 4 etc.
   This is the same as the default Pi-Star gateway but will not allow
   the use of 7 digit talk groups unless you select a raw mode network as described above.
   
  Item 6:
   will Ignore the existing Configuration File and
   will Compile a new Binary if Required and 
   will Install the Binary File
   
  Item 7:
   will Restore the Original DMRGateway from /usr/local/bin/DMRGateway.orig
   ( If it exists )
   
  CAUTION: This script can not possibly handle all users special situations
  Use nano /etc/dmrgateway to check and configure what the script misses
   -------------------------------------------------------------------------------------
Note 2021-06-19
The Pi-Star update dated June 17, 2021 overwrites the DMRGateway Binary file with a Pi-Star Default.
Re-Running the ./binupdate.sh script in the DMRGatewa-5 directory will re-install DMRGateway-5 Binary

I have added a script in the DMRGateway-5 directory called GWConfig.sh That will help to install the DMRGateway and
Configure it according to information found in /etc/mmdvmhost.

Follow the instruction indicated below titled INSTALLATION of DMRGateway-5
The following is a typical rule set for Network 5 in 8 Digit Translation Mode
TGRewrite0=2,15000001,2,1,999999                // Talk groups 15000001 to 15999999  = 1 to 999999  Max 6 digits
TGRewrite1=2,1000001,2,1000001,5599999     //Allows use of 7 digit talk groups
PCRewrite0=2,15000001,2,1,999999
SrcRewrite0=2,1,2,VE3RD,9999999
