SDI-12 Transparent Mode #35

Closed AshuJoshi closed 7 years ago

AshuJoshi commented 7 years ago

Does this library support the "transparent mode"? I have an Enviropro Probe that I am trying to use with this library but so far no luck in getting any response back from the probe.

Hi @AshuJoshi - as far as I understand it, "transparent mode" just means that it looks like your computer is speaking directly to the sensor when in fact it is talking to the data logger transparently.

See examples/g_terminal_window/g_terminal_window.ino for an example of how to do this.

Thanks - tried that but basically I did not get any response back. I am basically new to SDI-12. This is the probe that I am using -EP100 Here is the SW manual for the probe.

I am using an Arduino Uno. The probe needs supply voltage in the range 6V to 15V - I am powering the probe via a separate DC power supply at 12V - connected the red and black to the power supply.

The blue - or the data wire - I have tried connecting with different data pins - 3, 8, 9, 12 but no change in behavior.

Reading what I can from the Enviropro documentation, it looks like it's the probe itself that needs to be in "transparent" mode to talk to a sensor with standard SDI-12 commands. I found instructions in the EnviroPro Configuration Unit (EPCU) manual (http://www.enviroprosoilprobes.com/Files/EnviroPro_EPCU_User_ManualV2.pdf) on how to put the sensor into transparent mode (see page 14), but I can't find any manual for the sensor itself or any instructions on how to get into transparent mode without the EPCU device. I suggest you contact EnviroPro directly to ask them.

I also suggest you try posting in the Envionmental Sensors form at envirodiy.com (https://envirodiy.org/forum/environmental-sensors/) to see if you can get a response from someone familiar with this particular probe.

I am going to close this issue because it's sensor specific and not actually a problem with the library itself. If you do find that there's something about the library itself causing the problem, please reopen the issue.
