I built a sensor using arduino board + RFM95-915MHz LORA SX1276 wireless transceiver module. My antenna is about 80mm in length. I can see the JoinRequest and JoinAccept on the helium console but I don't see the sensor receiving EV_JOINED event. The sensor keeps trying to join the network. Also the JoinRequest message is not consistently sent right after resetting the board, sometimes it is quick, sometimes it is after number of tries.
Any ideas what I shall be checking for? Could it be the distance between my sensor the closest hotspot it can reach?
Attached are the screenshot for Join messages on console and logs from sensor showing it keeps trying.
