I am proposing to use communication using MQTT throughout my Home Automation project and have sufficient hardwired I/0 to require 2x Arduino Megas to be part of the system. All control is localised within a single cupboard in my house, so was looking to connect Ardunios to Pi with USB, whilst maintaining MQTT. For this I found a potential solution in Serial2mqtt. However during installation it was found that the latest OpenHabian (i’m using OpenHAB 2.5.5) that utilises GLIBC version 2.24, however serial2mqtt requires version 2.28, with the following message appearing:
./serial2mqtt.armv7l: /lib/arm-linux-gnueabihf/libc.so.6: version GLIBC_2.28 not found (required by ./serial2mqtt.armv7l)
So I’d like to check if any update in the build will include an update of GLIC to version 2.28 or beyond?
Or I would have to purchase hats for the arduinos to get them on the network…
