May possibly work with D74 but not tested. +#26FEB2024 KM4ACK + +#HELP + + #Before using this script, the D75 should be paired and trusted using the Bluetooth GUI app + #found in Linux Mint. + + #KISS 12 TNC MUST be turned off for GPS. It must be turned ON for Winlink, packet, and APRS. (Function 5 on radio) + #Bluetooth MUST be turned on on the radio. Also, GPS must be set to Bluetooth (Menu 981) and KISS must be set to + #Bluetooth (Menu 983). + + #Start by scanning for your radio so the mac address can be recorded. By clicking the "Scan" button, hcitool scan + #will be run in the background and look for the radio. The radio should be in "Pairing Mode" (menu item 934) before + #starting the scan. It takes ~20 seconds for the scan to complete and display the results. If the scan does not + #see the radio, verify that Bluetooth is on and "Pairing Mode" is enabled on the radio and try again. A few + #times I have seen it take four or five scans to find the radio. + + #Next, start either Winlink, GPS, or YAAC. + + #Winlink requires that Pat Winlink and ax25 are both installed. D75-Connect will create the connection to the radio, + #start ax25, and open the Pat mailbox in a browser window. + + #YAAC connection require that YAAC is installed. When connecting YAAC with the radio, the script creates a new port + #(/dev/rfcomm0). YAAC will open with a custom blank "D-75" profile which can be tailored to the D75 without messing + #with other YAAC configurations that may be present on your machine. D75-Connect assumes that YAAC is installed at + #$HOME/YAAC/YAAC.jar. If you used Build a Pi or 73Linux for the install, this should be the path. However, the + #YAAC path can be modified in the yaac function found below. Before using YAAC with the script, be sure that + #KISS 12 is diplayed on the radio. This can be enabled with function 5 on the radio. + + #GPS requires that the gpsd package be installed on your system. Before attempting to stream the GPS data over + #Bluetooth, be sure that both the APRS modem & KISS 12 are not enabled. (Function 5 on the radio) + + #Before closing the D75-Connect App, you should choose "Kill Connection" which will release rfcomm, stop + #kissattach, and close YAAC and remove rfcomm from gpsd if configured. You should also use the "Kill Connection" + #when changing between Winlink, GPS, and YAAC connections. + + #D75-Connect is NOT compatible with Wayland + + #TROUBLESHOOTING + #After you have chosen a connection method, the Bluetooth icon on the radio should be blue. If it remains grey, + #it did not connect successfully. If the icon isn't blue after 10 seconds or so, kill the connection and try again. + #Only packet Winlink sessions will work with the TNC in the Kenwood D75.
