Receiver example not working with Arduino MKR WAN 1310 #26

Closed rrbonham96 closed 3 years ago

rrbonham96 commented 4 years ago

I'm trying to send basic Lora packets to the LoStik using the radio receiver example using an Arduino running the example radio sender code from https://github.com/sandeepmistry/arduino-LoRa/blob/master/examples/LoRaSender/LoRaSender.ino, but I'm not seeing any data show up on the receiving end. I'm not really sure what I'm doing wrong.

Arduino serial monitor: 14:34:36.035 -> LoRa Sender 14:34:36.461 -> Sending packet: 0 14:34:41.505 -> Sending packet: 1 14:34:46.534 -> Sending packet: 2 14:34:51.560 -> Sending packet: 3 14:34:56.607 -> Sending packet: 4 14:35:01.643 -> Sending packet: 5 ...

Based on that example code there seem to be a lot of things missing. Do you need to specify which pins the SPI is hooked up to on the LoRa module? Spi frequency? Set the coding rate? Spread factor?

I did some research and finally found the solution to this. The issue wasn't anything to do with SPI since the LoRa module is built into the MKR WAN 1310. I had to set the spread factor on the LoStik to 7 since that's what the Arduino defaults to. I also had to set the sync word to 12 to match the default used by the Arduino. I think that's all it took to get communication up. I am still getting radio_errors for the actual data, but that's a different issue I have yet to look into.
