I use currently the SRTR module with the red board. It works very well. I was asking myself to send the data obtained from the RFID module (RSSI, ID,…) by Lora to another Lora receiver. One possibility is to connect the SRTR to the arduino MKR WAN 1300. Is it working? Or maybe there are other solutions?
SparkFun hasn’t tested the Simultaneous RFID Reader with an Arduino MKR WAN 1300. I don’t see why they wouldn’t work together but I was unable to find any direct examples for this. However you could look into [this post to help for reference on using the RFID reader and LoRa.
