Does anyone have any experience with connecting 2 of the dragino la66 lora shields (868MHz)for adruino uno(one as a sender and other as a reciever), I havent found code online for these purposes, and i do not know what libraries or pins to use to be able to send or recieve data?
Those modules use an AT Command protocol via a UART-TTL interface. This type of LoRa device tends to use bespoke commands, so standard LoRa libraries and examples, of which there are many, wont work.
You would expect that Dragino would publish working examples for thier product.
Dragino does publish working examples in the user manual: LA66 LoRaWAN Shield User Manual - DRAGINO.
I tried the first one, LA66-LoRaWAN-shield-AT-command-via-Arduino-UNO. It does work but I am having trouble developing my own similar example.
Their previous LoRa Shield was very easy to use and I was able to develop a relatively complex project with it. With LA66, I am having trouble even to get started. The problem appears to reside in the communication between Uno and LA66.
A search of github does show some other examples. Am trying to learn from what is available.
