[BUG] version 3.6.2

[pro100805]

After configuring the gateway and adding the connector, nothing happens for some time. The devices described in the connector do not appear on the TB server.

some time later, the following message appears

Hi, @pro100805, thanks for your interest in ThingsBoard IoT Gateway!
We will fix this bug as soon as possible.

[samson0v]

@pro100805 fix is available in the master branch. If something goes wrong, let us know.

[pro100805]

Thank you for your prompt reply.
I am using DEB package for my installation. Please give instructions how to integrate your modified MASTER BRANCH into my installation. If possible, thank you in advance

@pro100805修复已在 master 分支中提供。如果出现问题，请告知我们。

After modification according to the fix file, __get_master in modbus_connector.py file will show slave. host as None. Is this an error?

[pro100805]

Thank you, you've given me an idea and I think these are the changes that need to be made.

[pro100805]

I'll make the changes and let you know what the result is.

[samson0v]

@tangchengxiang666, it is ok

[pro100805]

It's not as easy as I thought. It's possible that you need to rebuild something after the changes. I don't think I can do it without help.

@tangchengxiang666，沒有關係

After repairing it using the file you provided, it is still not available for serial cases
