Support Questions / Modbus TCP driver behavior
« on: January 23, 2018, 02:47:02 PM »
Hello,
I'm trying to get Modbus TCP working with an ESP8266 and not getting much luck. So before digging into the ESP8266 Modbus implementation, I'd like to know a couple of things about how the Modbus driver works.
Does the driver open and close a connection on each transaction or is it expecting the connection to remain open?
Is it smart in the sense of grouping addresses in order to minimize the requests or does it make a single request per variable defined?
