PROBLEM DESCRIPTION

I've noticed it's reporting this on the new version:

23
23:12:54.790 TYA: DP len exceeded dpId=103 type 0 (74 > 16

That shouldn't be implemented like that. Type 0 data has spec length 1 to 255 bytes.

Old version didn't have that complain about length

TuyaSend6 is not working at all and since weblog 3 isn't reporting the sent payload it's impossible to debug

There is something missed in the initialisation process, none of the TuyaSend commands work until I do a SerialSend for that dpId. Again not able to debug because no information shown in the log.

After reverting to release 12.2. everything works as expected. Upgrading back to dev gives same issues.
