Framing error on DALI RS485 gateway

[avolle]

First, run "Scan gateways" and see if the RS485 gateway is still there. If it appears in the list then try testing again with a single ballast and see if works. If it does not appear it's possible the it is damaged and must be replaced.
Another thing to try is to send a broadcast arc command from a script to check whether you can control ballasts this way or not.

Thanks for your reply. I always find the gateway I expect, so it's in the list.

I ran this script:

Code:

require 'user.dali'

res, err = dalicmd(0, 'arc', { addrtype = 'broadcast', value = 0 })

log(res, err)

What came back was: 

Code:

dali_test 21.09.2021 12:24:34
* arg: 1
  * nil
* arg: 2
  * string: timeout

I've now tried the following:

• Deleting the `user.dali` script and rebooting. The script re-appears as expected, but still does not work.
  
• Use another RS485 port on the LM5. The gateway appears after changing the port in the DALI tab, but still can't find any lamps or control them by scripts.
  

I have another LM5 with me, so I'll now be trying to replace the other one.

Edit: After swapping the LM5s, I'm still getting a framing error on the network and no devices appear in the device list. Could the DALI gateway be broken? I bought it in July and it's only been used at home for testing one lamp for this project. I can write new gateway ID to the gateway, the LED is on when i press the button on it. It appears to be fine from the outside.
