It was necessary to add #define LORA_BUSY 33 to fdrs_node_config.h, which then produced another error caused by having both USE_LORA and USE_ESPNOW defined. I commented out #define USE_ESPNOW which then produced yet another error which was resolved by changing a line in fdrs_node.h The offending line was if (is_controller){ handleIncoming(); which I changed to if (isControl){ handleIncoming();

Finally, by adding these two lines to fdrs_node_config.h:

define HASL 280

define P_CORRECTION HASL * 0.1222

and changing this line in BMP280_fdrs.ino: loadFDRS(bmp.readPressure() / 100.0F, PRESSURE_T); to this: loadFDRS((bmp.readPressure() / 100.0F) + P_CORRECTION, PRESSURE_T); I am able to get the correct MSLP for the sensor

Thanks for the report, Peter! The first issue was on my end: The SX1278 chip doesn't need the LORA_BUSY pin to be defined, so on gateways, I have code to define it if the user does not. I had forgotten to add that functionality to nodes, and just fixed it.

Next, a node may use either ESP-NOW or LoRa, but not both. I'm not sure if I documented that somewhere or not, but I'll make a note of it in the node readme.

I think your final problem will be fixed by getting the latest copy of the repo, as I recently fixed the is_controller issue.

isControl is an Arduino function and is unrelated to FDRS.

Let me know if this irons things out!

Your code is very nicely written and therefore easy to troubleshoot. I understand the architecture much better now. I'm looking at things like NPK probes, ultrasonic tank level sensing, reed switch gate monitors and stepper motor tuning knobs. small servos also have some farm applications.

[timmbogner]

I appreciate it, but must pass the credit to various contributors for their guidance in organizing the code and repo. This thing was a mess back when it was just me 😅

If you're working with a sensor that is not covered in the FDRS examples, please feel encouraged to contribute an example sketch! I'm a bit surprised that there isn't an ultrasonic sensor sketch. I know I've used one with FDRS before, so I'll have to look for it. I'm going to be using a servo to tip a rain gauge I built from this cool project but I haven't had a chance to do the example code.

Farmers love rain gauges ;)
