TRB245 fw TRB2_R_00.07.07.1 not working MQTT Modbus Gateway

Hello, after update firmware to TRB2_R_00.07.07.1 MQTT Modbus Gateway not working properly.
Here is communication sample:
request: “1 50 default 1 1 3 8449 1”
response: “50 ERROR: read register failure - Invalid argument”

But trough Modbus Serial Client, this request:


will return correct value: “Request successful, result: [3]”

I would try to downgrade firmware, but I am managing device through Zerotier. But after loosing configuration It will be unreachable…

I have the same issue - maybe the ascii protocoll has changed??
the following was workng in older fw version
request:
1 103100043 1 1 31 3 43 1
response:
103100043 OK 19500

with fw 0.7.7. I get this error
request:
1 103100043 1 1 31 3 43 1
response:
103100043 ERROR: read register failure - Invalid argument

Support has been getting worse over the years.
I have several issues and each and everyone gets the standard reply: wait for next firmware release or, if one minor release behind, pls install newest firmware, should be fixed. But it never is fixed.
Terribly annoying is that topics will be automatically closed after 15 days, while the problem isn’t fixed yet. Maybe its a way to disencourage and give up.
