Hello,
I have many teltonika gps trackers models FMB130 and FMC125 and digital flow meters (SIKA VTY10) connected to arduino uno MCU for measuring water flow. Is there any way the digital output sign from arduino to be read from the teltonika gps using rs485 input from FMC125 or directly from the sensor using the pulse input from FMB130 ?
At the moment, I convert the digital signal of the sensor to an analog voltage with arduino and use the analog input of the tracker to read that voltage value.
