Question

It is not clear what the best approach is to obtain gps data and UTC time.

I have two devices connected, wireless, to the RUT955: a windows PC and an embedded system (Linux OS).

The idea is to use python to obtain UTC and GPS data (Latitude, Longitude) from the RUT955 using for example requests (https://requests.readthedocs.io/en/master/).

What is the best approach.

Hi,

You can simply get data from router via SSH, command: gpsctl.

Also using JSON: https://wiki.teltonika-networks.com/view/Monitoring_via_JSON-RPC

Or using Modbus: https://wiki.teltonika-networks.com/view/RUT955_Modbus or SNMP: https://wiki.teltonika-networks.com/view/RUT955_SNMP

More details about GPS you can find here: https://wiki.teltonika-networks.com/view/RUT955_GPS

Comments

Yes this works fine but in case of JSON, you must send your router credentials in order to get your session ID.

I have no experience using SNMP. Any examples, in Python, are welcome.

Why is it not possible to perform this with MQTT.

Hi,

Via MQTT these parameters are not included, support only these parameters: https://wiki.teltonika-networks.com/view/Monitoring_via_MQTT#How_MQTT_works

Unfortunately we do not have example how to use SNMP via Python, but details about SNMP you can find here: https://wiki.teltonika-networks.com/view/RUT955_SNMP

# A solution for modbus TCP use pymodbus

from pymodbus.client.sync import ModbusTcpClient

host = 'your_host'
port = your_port

client = ModbusTcpClient(host, port)
client.connect()

response = client.read_holding_registers(reg_address, nmb_registers, unit=device_id)
print(response.registers)
