I am working on a project with the SX1278. This is a LoRa only project and not LoRaWAN. I have a problem with the fact that I only receive 3/10 of the messages I send.
Freq = 433500000
SF = 7
BW = 250 kHz
CR = 4/5
I have tried different combinations and the result is always the same only 3/10 messages. I don’t know if there could be a problem with the fact that I am currently testing the transmission in only one room, at a distance of 5 m.
I use STM32 with this library:
And a Raspberry pi with this library:
I would appreciate any advice.
