All,

My DVSwitch system as suddenly stopped connecting to BM.  I've made the changes to the MMDVM_Bridge file as previously noted:

[General]
Callsign=N4UPC
#Id=316235620
Id=3162356
Timeout=180
Duplex=1

Still no joy.  All I get in the MMDVM_Bridge.log is:

E: 2021-03-14 23:31:05.954 DMR, Master is closing down
M: 2021-03-14 23:31:05.954 DMR, Closing DMR Network

I also did an upgrade and rebooted the system afterward.  Stumped!
