DALI connection refused

[Bitver]

Hi there,

I faced an issue with internal DALI on LM4.
All devices are shown in dali configuration and easily re-scan, re-bind addresses in GW-internal devices, but when I try to run some scripts, I always get "connection refused" error, for example:

Code:

require('user.dali')
res, err = dalicmd('internal', 'setdtr', { addrtype = 'broadcast', value = 0 })
log(res, err) -- nil, connection refused

What is it may be or am I doing wrong?
