We are a stem learning center trying to connect the sparkfun explorable Lora module to a arduino R3 and have tried to use I2C to do this. We have an SSD module on the arduino storing sensor data and we want the explroable to grab that data and send it periodically. To start we need the two devices to see one another and then be able to read the ssd. but that is step two and step one is killing us. Advice to get these talking. We think the IDE has the proper boards set up already and we can make two lora thing plus talk to one another as standalone units.
I can just offer a general note that you’ll likely want to PUSH the data from the arduino to the external MCU (instead of having the external device try to read the SSD) as a data package; you could perform this as batches using the standard UART RX/TX pins (with appropriate coding) and then have that forwarded from the explorable
Since you CAN get 2 explorables talking, it might be easier to break this into 2 smaller projects…get the arduino to output to one, then combine the code that works for the 2 explorables talking
Thanks for the suggestion. Im not sure we can even get the arduino to “see” the LoRa Explorable to push the data to it. Ive checked the libraries, tested pins, etc. We havent tried UART to my knowledge. So we will give this an attempt.
