DALI on LM5

[LKBA]

Hello,

I have just migrated whole project from LM4 to LM5, and my DALI feedbacks stopped working.
All the commands go through - all the lamps go on/off and dimms with no problem, but when queryingactual to read the status i get such error messages:

Event for DALI READ ALL (15/7/3) 22.12.2016 15:51:10 * string: rx error

script:
require('user.dali')
res, err = dalicmd('internal', 'queryactual', { addrtype = 'short', address = 0 })
if res then
   log(res:byte())
else
   log(err)
end

when querying any other address i get:


Event for DALI READ ALL (15/7/3) 22.12.2016 15:52:44 * string: reply timeout

When querying all the ballast it's the same:

Event for DALI READ ALL (15/7/3) 22.12.2016 15:54:08 * string: reply timeout

script:

require('user.dali')
res, err = dalicmd('internal', 'queryshortaddr', { addrtype = 'broadcast' })
if res then
   log(res:byte())
else
   log(err)
end


Then i tried scanning through devices and after scan 16 of connected ballasts has disappeared, i cannot detect them again. They were visible before the scan.
Tried rebooting LM, turning off power supply of DALI line.
What else should i try?

Holidays are coming and customer is getting angry. Please help
