I got opentherm gateway running version 3.4 and I have pulled out max232 IC. I have connected arduino to communicate with opentherm-gateway.
Everything works fine in monitor mode. I write up a basic sketch. It prints all serial data readings to arduinos serial interface and I can also use arduino's com port on otmonitor.exe without any problems.
But I cant send send data to opentherm gateway. It does not respond me from otmonitor.exe interface or arduino serial interface via send button.
(As I know it needs to respond from one of those codes to me http://otgw.tclcode.com/firmware.html#configuration)
I also bridged tx-rx connections as mentioned here : http://www.opentherm-gateway.com/media/ ... ctions.pdf
Could anyone help me to try something else to send commands to my opentherm-gateway and make it respond?
Here is the basic sketch I wrote;
Code: Select all
void setup()
{
Serial.begin(9600);
}
void loop()
{
if (Serial.available() > 0) {
incomingByte = Serial.read();
Serial.print(incomingByte);
}
Many thanks.
