This is more a bug report than a question...
I run a SignalK server on Ubuntu Linux, attached through an Actisense NGT-1 to the N2K bus of the boat which is on /dev/ttyUSB0. I further use VictronConnect to connect to my two Victron devices (a battery charger and a battery monitor) via Bluetooth. I recently discovered that as soon as I start VictronConnect I got some error messages in the syslog and there are no more inserts into the InfluxDB from SignalK (which is visible on the Grafana dashboard because no data is display in the graphs during that time):
Apr 9 18:43:41 mi5 systemd[1101]: Started VictronConnect. Apr 9 18:43:44 mi5 signalk-server[758]: DLE followed by unexpected char , ignore message Apr 9 18:43:54 mi5 signalk-server[758]: message repeated 332 times: [ DLE followed by unexpected char , ignore message] Apr 9 18:43:54 mi5 signalk-server[758]: DLE followed by unexpected char , ignore message Apr 9 18:43:57 mi5 signalk-server[758]: message repeated 84 times: [ DLE followed by unexpected char , ignore message]
I then looked a little bit more into detail and ran lsof. It shows that the VicronConnect app somehow accesses the USB device which seems to cause the problem:
VictronCo 36212 36250 QSGRender mi5 18uW REG 0,32 100 18 /run/lock/LCK..ttyUSB0 VictronCo 36212 36250 QSGRender mi5 19u CHR 188,0 0t0 539 /dev/ttyUSB0
As soon as I close the VictronConnect, everything continues to work as expected. So it looks like that the VictronConnect claims a USB device which it shouldn't.
