A few things spring to mind, is there any validation on the IDs used? They're registered as DMR IDs but I don't know if something special is required for D-Star.
Secondly, for the DStar instance of Analog_Bridge, does the following work? Should I be using a specific TG etc to get into XLX?
; The metadata below is used when ASL is the source since it does not have any concept of digital modes gatewayDmrId = 2348479 ; ID to use when transmitting from Analog_Bridge 7 digit ID repeaterID = 234847911 ; ID of source repeater 7 digit ID plus 2 digit SSID txTg = 4003 ; TG to use for all frames sent from Analog_Bridge -> xx_Bridge txTs = 2 ; Slot to use for frames sent from Analog_Bridge -> xx_Bridge colorCode = 1 ; Color Code to assign DMR frames
