Please include the following information, in order for us to help you as effectively as possible.

  • What product do you wish to discuss? RAK13010

  • What firmware are you using? Arduino BSP

  • What firmware version? Can it be obtained with AT+VER=?

  • Computer OS? (MacOS, Linux, Windows) Windows

  • What Computer OS version? Windows 11

  • How often does the problem happen? Every SDI12 sensor I’ve tried

  • How can we replicate the problem? I’m using an RAK4631 on an 19001/19007. The SDI12 sensors I’m trying to use are a TEROS12 and Sentek drill and drop.

  • Provide source code if custom firmware is used or link to example if RAKwireless example code is used. RAKwireless_SDI-12 library v1.0.1, I haven’t had any luck with any of the example files. I used the constructor RAK_SDI12 mySDI12(WB_IO5, WB_IO6, WB_IO4);

Hi again all, I’ve been trying to get the RAK13010 SDI-12 module working and can’t get any sensor response after extensive troubleshooting. I’ve tried testing with both internal power and an external power supply.

The sketch compiles and uploads successfully but I always get a response timeout. I do notice current draw on the power supply, when used, so the sensors are powering on. I also checked to make sure the 13010 is sending 12v and it is. Swapping sensors, baseboards, etc, made no difference.

Any help is appreciated.
