command that returns the date and time and the day of the week

Sato

Thank you @kl3m3n,

I've tried this, but it doesn't work, what mistake am I making?

  Serial.print("MQTT CONECTED " );
  Serial.println(mqttClient.state());
  mqttClient.subscribe(&Out[0]); //subscrive topic

mqttClient.publish(&In[0], "RTC UID:rtc1 HID:rtc\r\n");

Main loop {
//for testing every 1000ms
Serial.println("Get rtc ");
//mqttClient.publish(&In[0], "@rtc1 RTCF:'HH:mm:ss' RTCR:2.0\n\r");
mqttClient.publish(&In[0], "@rtc1 RTCF:HH:mm:ss RTCR:2.0\n\r");
}

void parseGuioMsg(const String &msg) {
Serial.print("Callback Gui-O ");
Serial.println(msg); // @init usr: //// here without reaction

if (msg.startsWith("@rtc1")) {
Serial.print("Show RTC "); // here without reaction too
Serial.println(msg);
}
}

Hello kl3m3n,

Now i receive the callback @rtc1. The ceation of the command was on the wrong part of the code.

Sorry and Thank You

@Sato Yes, you were missing the '|' character.

Hello @kl3m3n,

You are right, but i continue have a problem with RTC, the ddd show not the dayofweek. Have you a idea what it is wrong?
Thank You

void generateTheGUI {
getRtc = 0;
Serial.println("Create command RTC");
mqttClient.publish(&In[0], "|RTC UID:rtc1 HID:rtc\r\n");
app_on = 1;
}

Main loop {
//only one time
if ((app_on == 1) && (getRtc == 0)) {
//mqttClient.publish(&In[0], "@rtc1\n\r"); ////same output on Serial Monitor
//mqttClient.publish(&In[0], "@rtc1 RTCF:hh:mm:ss ddd RTCR:5.0\n\r"); //same output on Serial Monitor
mqttClient.publish(&In[0], "@rtc1 RTCF:'hh:mm:ss ddd' RTCR:1.5\n\r"); //same output on Serial Monitor
delay(150);
mqttClient.publish(&In[0], "@rtc1 RTCE:0\n\r"); //Disable RTC ??????????????
getRtc = 1;
delay(150);
}
}

void parseGuioMsg(const String &msg) {
if (msg.startsWith("@rtc1")) {
Serial.print("Show RTC ");
Serial.println(msg);
}
}

On Serial Monitor, a few times, like this...
Show RTC @rtc1 2025/07/07 22:32:31:696 dev:W 0001 x.x uuid:d3f1c986-16b3-47
End Parse
Show RTC @rtc1 2025/07/07 22:32:33:696 dev:W 0001 x.x uuid:d3f1c986-16b3-47
End Parse
Show RTC @rtc1 2025/07/07 22:32:34:694 dev:W 0001 x.x uuid:d3f1c986-16b3-47
End Parse

Hello @kl3m3n,

Now it works.

@rtc1 2025/17/12 20:17:05 sábado dev:W 0001 x.x uuid:d3f1c986-16b3-47

In this case, the WeekDay is sábado = Saturday. My question is how is the WeekDay, if the Guio is used in UK or Germany and so on...

Saturtday or Samstag or?

Thank You
Best regards

@Sato said in command that returns the date and time and the day of the week:

2025/17/12

Show on callback
RTC @rtc1 2025-37-13 20:37:01 dev:W 0001 x.x uuid:d3f1c986-16

No, it not works, the date is wrong 2025/37/13, the time is correct

Thank you
Best regards

@Sato Hi!

Yes, the localisation can be a problem.
I will fix the RTC so it will return the day of the week as a number.

@Sato said in command that returns the date and time and the day of the week:

No, it not works, the date is wrong 2025/37/13, the time is correct

Can you please provide the initialization for RTCF for this?

Thanks.

Hello @kl3m3n,

mqttClient.publish(&In[0], "|RTC UID:rtc1 RTCE:0 HID:rtc\r\n"); // Disable RTC

if i use this, the time is correct but it go few times on the callback, but i only need it one time!!!!!!!!!
mqttClient.publish(&In[0], "|RTC UID:rtc1 HID:rtc\r\n");

mqttClient.publish(&In[0], "@rtc1 RTCF:"yyyy-mm-dd hh:mm:ss" RTCE:1\r\n");

void parseGuioMsg(const String &msg) {
if (msg.startsWith("@rtc1")) {
getRtc = 1;
mqttClient.publish(&In[0], "@rtc1 RTCE:0\n\r"); // Disable the RTC

Thank you
Best regards

@Sato Hi,

try setting the RTCR parameter to a low value, e.g. 0.1. This should give you updates with an interval of 10 seconds, which should be enough for you to disable the RTC. You can even go lower, up to 100 seconds.

Note that when creating the RTC, it will give you the time immediately and then with a specified interval.
