Problems

Problem

mbus-serial-scan

mbus-serial-scan: error while loading shared libraries: libmbus.so.0: cannot open shared object file: No such file or directory

Search the file: sudo find / | grep libmbus.so.0

/usr/local/lib/libmbus.so.0

export PATH=$PATH:/usr/local/lib

echo $PATH

/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/games:/usr/games:/usr/local/lib

Still same error, to be continued on github.

On another Ubuntu machine with libmbus installed from prebuilt binay it's located in /usr/lib/libmbus.so.0

Solution

Make a soft link between current position and expected position:

sudo ln -s /usr/local/lib/libmbus.so.0 /usr/lib/libmbus.so.0

Problem

mbus-serial-scan -b 2400 /dev/ttyUSB0
mbus_serial_connect: failed to open tty.mbus_connect_serial: Failed to setup serial connection to M-bus gateway on /dev/ttyUSB0.
Failed to setup connection to M-bus gateway

Solution

Run as root: sudo mbus-serial-scan -b 2400 /dev/ttyUSB0

Debug

Add the -d switch to output debug info.

sudo mbus-serial-scan -d -b 2400 /dev/ttyUSB0
