I'm looking for a way to transfer data from an arduino or raspberry pi at a long range to connect it to my stree mailbox. I have looked into GMS module but don't wanna pay the sibscription fee. Right now my best options are xbee or class 1 bluetooth. Cheaper the better. Any ideas?
PS: there is no LoRa network available in my area
Try looking for long range nrf24l01+
