Mbus

[Christopher]

Hi. 
I'm trying to poll some carlo gawazzi meters an have tried everything (i think) but are nok able to get a respone from them.

I'm using this script and have tried to change the baud rate and duplex.
I have tried to scan for 254 elements,

Code:

require('mbus')

mbus.init('/dev/RS232', 2400)


res, err = mbus.scan( 0, 10, 5)
log(res)
log(err)

I have also tried to check my connections on the Rx/Tx both on LM5 and the meters. 

But still I only got these responses:

Code:

m-bus 18.08.2023 12:45:44
* table:
m-bus 18.08.2023 12:45:44
* nil

HW: LM5 Lite + Ext (i.MX6)
SW: 20230607

I there something I'm missing out?
