Most websites will tell you that the SX1276 has better receiver sensitivity and they quote the “-148 dBm” figure. However, in the datasheet it states you only get that sensitivity for a SF of 12 and a BW of 7.8 kHz.
I’m interested in the 868 MHz ISM band and a BW of 125 kHz. Am I interpreting the datasheets correctly that the SX1272 has better sensitivity than the SX1276 in my case? I’m referring to page 19 of the SX1272’s datasheet and page 20 of the SX1276’s datasheet.
That’s interesting I also had the idea that the SX1276 had better sensitivity but as @Timsek says if you actually look up the bandwidth and datarate in the datasheet it seems the SX1272 is better at least for LoRaWAN
Makes me feel better that the RM186 - which is the module I use the most - has the SX1272
