Arduino Opta for GPS on Cloud

[Marian018]

Hello ,

I need a solution to display the position of an irrigation pivot on Arduino IoT platform. We have used Arduino Opta for other irrigation systems to control pump and valves and this is why Arduino Opta would be the preferred solution as well by client. I looked into Neo 6M GPS Sensor but I would need as well to read it by Opta. I am unsure if opta has any pins that I can use for Tx & Rx to connect with my GPS... obviously the I1-I9 are 24V DC IN or 0-10 V AI.

I have tried the GPS with no luck.

Is there any information about Serial 2 and Serial 3 pins?

Thanks in advance,
Marian

I am trying to connect the NEO6 GPS module to synchronize the RTC. I have uploaded some information at this link.

Serial ports on Opta

In the OPTA WiFi documentation, I found information that the AUX connector for the expansion module has RX and TX pins. I haven't figured out how to use them yet. If anyone knows which Serial it is, please help. From what I understand, the connections marked in red are actual connections, while those in blue are not present on the board. I am also trying to connect a 3.3V TTL device (RX/TX) to the RS485 via a converter. I will let you know if I succeed. [schematic_aux]

EDIT
I just managed to communicate NEO6 GPS with OPTA WiFi using AUX and Serial1.

void setup() {
  Serial.begin(9600);
  Serial1.begin(9600);
}

void loop() {
  if (Serial1.available() > 0) {
    char received = Serial1.read();
    Serial.print(received);
  }
}

If you open Serial Monitor you will see all the informations that NEO6 is sending. Now its just your creativity about how and which data are you gonna use.
