localbus

[Svanda]

You need to call step for it to receive data. You should also define callback before setting it.

Code:

if not lb then
  lb = require('localbus').new(1)

  function groupcallback(event) 
    log(event)
   
    if event.dst == '0/2/1' then   
      local value = knxdatatype.decode(event.datahex, dt.uint16)   
      log(value)
    end
  end

  lb:sethandler('groupwrite', groupcallback)
  lb:sethandler('groupread', groupcallback)
  lb:sethandler('groupresponse', groupcallback)
end

lb:step()

Hello Admin,
can I ask you for documentation for localbus library?

We are confusing what happens with queue if is too long?
Can get somehow batch of e.g. ten telegrams in one step?
Can we filter somehow range of group addresess to listen?
What is return value of lb.step?

Thanks a lot!
