Hi there.

We have a project related to water flow meter.

And we want to MBUS connection for data transfer. is there any wired MBUS slave lib for MSP430 MCU?

Hello Mesut,

I was able to find an application note regarding a wireless M bus solution. See below.

In regards to the wired Mbus solution, you would need to add an external transceiver like the TSS721A for level translation to get the data to a standard UART level. I don't believe we have a library available for the wired M bus solution. Some details can be found in the thread below.
