Hello Philip,
After one day poking around this matter, I can say that the reported issue isn't related with the latest software, it can also happen with other versions. The issue seems related with the first time the serial port is opened after powering up the receiver.
Technically, the issue seems related to the DTR line (which drives the GPIO0 pin to low). I will continue investigating.
Interestingly, when it happens, if we close CumulusMX, press the reset button to recover from the blank screen, and then (when the receiver is ready) start CumulusMX again, everything will work fine.
With Cumlus 1, this issue doesn't happen. Haven't tested with WeeWx yet.
