TīmeklisI was trying Lora Communication for a Project and i m having trouble getting the required range. Im using an Ra-02 module (433Mhz) with antenna(433MHz 3db 5cm) and i was able to get a 300m range(Not line of sight). I also tried the Helical antenna model Ra-01 but results were almost same(240m). The code i referred to is this. Im also attaching ...
