Arduino Opta for GPS on Cloud

Official Hardware Opta
1

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.

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.

Hi @darrag212
Just a quick followup on weither you succeded in connecting a 3.3V TTL GPS module (RX/TX) to the Arduino RS485 via a converter?

I am building an RTU for distribution transformer and I would like use the a GPS module

Hi gwepogi,

My first idea was to use converter, but Serial port was a solution for me, so I didn’t use any unnecesary devices, just connected GPS module straight into Opta.

Hello All,

My hardware mounted in a real project in a cabinet outside where non technical people might be manipulating the system hence I don’t want to solder anything but only use screw terminals.

The OPTA MODBUS / Serial is not working for me.

GPS module is working fine with Modbus Poll on my PC however I tried a lot in OPTA and it is simply not functioning. I used 3 different OPTA PLC in our lab, no success.

I now bought MKR NB board and its GPS Shield and that is much cheaper, and I already can use build it GSM (even if it is only NB) and saves a lot of money on the industrial modem for OPTA . Not sure if MKR is industrial rated however I will give it a try. Tried to make OPTA modbus work for many months, it is not stable for my point of view.

Regards,

Marian

Thanks. The Serial port I have is currently connected to a LoRaWAN module. I was considering the I/O terminal of the Opta RS485. I do not know how feasible is that.
